2011-09-21 17:04:56 +00:00
demonstrate periodic health checking. Add "nodh" option to
fips_test_suite to skip very slow DH test.
[Steve Henson]
new function to lookup FIPS supported ciphers by NID
2011-09-14 13:25:48 +00:00
*) New function FIPS_get_cipherbynid() to lookup FIPS supported ciphers
based on NID.
[Steve Henson]
More extensive DRBG health check. New function to call health check for all DRBG combinations.
2011-09-12 18:47:39 +00:00
*) More extensive health check for DRBG checking many more failure modes.
New function FIPS_selftest_drbg_all() to handle every possible DRBG
combination: call this in fips_test_suite.
[Steve Henson]
Add support for Dual EC DRBG from SP800-90. Include updates to algorithm tests and POST code.
2011-09-09 17:16:43 +00:00
*) Add support for Dual EC DRBG from SP800-90. Update DRBG algorithm test
and POST to handle Dual EC cases.
[Steve Henson]
Add support for canonical generation of DSA parameter g. Modify fips_dssvs to support appropriate file format.
2011-08-26 14:51:49 +00:00
*) Add support for canonical generation of DSA parameter 'g'. See
FIPS 186-3 A.2.3.
Add support for Dual EC DRBG from SP800-90. Include updates to algorithm tests and POST code.
2011-09-09 17:16:43 +00:00
*) Add support for HMAC DRBG from SP800-90. Update DRBG algorithm test and
POST to handle HMAC cases.
Add HMAC DRBG from SP800-90
2011-08-08 22:07:38 +00:00
[Steve Henson]
Add functions to return FIPS module version.
2011-07-04 23:38:16 +00:00
*) Add functions FIPS_module_version() and FIPS_module_version_text()
to return numberical and string versions of the FIPS module number.
[Steve Henson]
Rename FIPS_mode_set and FIPS_mode. Theses symbols will be defined in the FIPS capable OpenSSL.
2011-05-11 14:43:38 +00:00
*) Rename FIPS_mode_set and FIPS_mode to FIPS_module_mode_set and
FIPS_module_mode. FIPS_mode and FIPS_mode_set will be implmeneted
outside the validated module in the FIPS capable OpenSSL.
[Steve Henson]
Always return multiple of block length bytes from default DRBG seed callback. Handle case where no multiple of the block size is in the interval [min_len, max_len].
2011-04-23 20:05:19 +00:00
*) Minor change to DRBG entropy callback semantics. In some cases
there is no mutiple of the block length between min_len and
max_len. Allow the callback to return more than max_len bytes
of entropy but discard any extra: it is the callback's responsibility
to ensure that the extra data discarded does not impact the
requested amount of entropy.
[Steve Henson]
Add PRNG security strength checking.
2011-04-23 19:55:55 +00:00
*) Add PRNG security strength checks to RSA, DSA and ECDSA using
information in FIPS186-3, SP800-57 and SP800-131A.
[Steve Henson]
Fix EVP CCM decrypt. Add decrypt support to algorithm test program.
2011-04-18 22:48:40 +00:00
*) CCM support via EVP. Interface is very similar to GCM case except we
must supply all data in one chunk (i.e. no update, final) and the
message length must be supplied if AAD is used. Add algorithm test
support.
Initial untested CCM support via EVP.
2011-04-18 14:25:11 +00:00
[Steve Henson]
Initial incomplete POST overhaul: add support for POST callback to allow status of POST to be monitored and/or failures induced.
2011-04-14 11:15:10 +00:00
*) Initial version of POST overhaul. Add POST callback to allow the status
of POST to be monitored and/or failures induced. Modify fips_test_suite
to use callback. Always run all selftests even if one fails.
[Steve Henson]
Add algorithm driver for XTS mode. Fix several bugs in EVP XTS implementation.
2011-04-15 02:49:30 +00:00
*) XTS support including algorithm test driver in the fips_gcmtest program.
Note: this does increase the maximum key length from 32 to 64 bytes but
there should be no binary compatibility issues as existing applications
will never use XTS mode.
Provisional AES XTS support.
2011-04-12 23:21:33 +00:00
[Steve Henson]
Extensive reorganisation of PRNG handling in FIPS module: all calls now use an internal RAND_METHOD. All dependencies to OpenSSL standard PRNG are now removed: it is the applications resposibility to setup the FIPS PRNG and initalise it. Initial OpenSSL RAND_init_fips() function that will setup the DRBG for the "FIPS capable OpenSSL".
2011-04-05 15:24:10 +00:00
*) Extensive reorganisation of FIPS PRNG behaviour. Remove all dependencies
to OpenSSL RAND code and replace with a tiny FIPS RAND API which also
performs algorithm blocking for unapproved PRNG types. Also do not
set PRNG type in FIPS_mode_set(): leave this to the application.
Add default OpenSSL DRBG handling: sets up FIPS PRNG and seeds with
Update CHANGES.

the standard OpenSSL PRNG: set additional data to a date time vector.
Extensive reorganisation of PRNG handling in FIPS module: all calls now use an internal RAND_METHOD. All dependencies to OpenSSL standard PRNG are now removed: it is the applications resposibility to setup the FIPS PRNG and initalise it. Initial OpenSSL RAND_init_fips() function that will setup the DRBG for the "FIPS capable OpenSSL".
2011-04-05 15:24:10 +00:00
[Steve Henson]
Rename deprecated FIPS_rand functions to FIPS_x931. These shouldn't be used by applications directly and the X9.31 PRNG is deprecated by new FIPS140-2 rules anyway.
2011-04-05 12:42:31 +00:00
*) Rename old X9.31 PRNG functions of the form FIPS_rand* to FIPS_x931*.
This shouldn't present any incompatibility problems because applications
shouldn't be using these directly and any that are will need to rethink
anyway as the X9.31 PRNG is now deprecated by FIPS 140-2
[Steve Henson]
Implement health checks needed by SP800-90. Fix warnings. Instantiate DRBGs at maximum strength.
2011-03-17 16:55:24 +00:00
*) Extensive self tests and health checking required by SP800-90 DRBG.
Remove strength parameter from FIPS_drbg_instantiate and always
instantiate at maximum supported strength.
[Steve Henson]
Add ECDH to validated module.
2011-03-09 23:44:06 +00:00
*) Add ECDH code to fips module and fips_ecdhvs for primitives only testing.
[Steve Henson]
New initial DH algorithm test driver.
2011-03-08 19:10:17 +00:00
*) New algorithm test program fips_dhvs to handle DH primitives only testing.
[Steve Henson]
*) New function DH_compute_key_padded() to compute a DH key and pad with
leading zeroes if needed: this complies with SP800-56A et al.
[Steve Henson]
Initial, provisional, subject to wholesale change, untested, probably not working, incomplete and unused SP800-90 DRBGs for CTR and Hash modes. Did I say this was untested?
2011-03-04 18:00:21 +00:00
*) Initial implementation of SP800-90 DRBGs for Hash and CTR. Not used by
anything, incomplete, subject to change and largely untested at present.
[Steve Henson]
Make fipscanisteronly build only required files.
2011-02-21 14:07:15 +00:00
*) Modify fipscanisteronly build option to only build the necessary object
files by filtering FIPS_EX_OBJ through a perl script in crypto/Makefile.
[Steve Henson]
Experimental FIPS symbol renaming. Fixups under fips/ to make symbol renaming work.
2011-02-16 14:49:50 +00:00
*) Add experimental option FIPSSYMS to give all symbols in
fipscanister.o and FIPS or fips prefix. This will avoid
Make -DOPENSSL_FIPSSYMS work for assembly language builds.
2011-02-17 19:03:52 +00:00
conflicts with future versions of OpenSSL. Add perl script
util/fipsas.pl to preprocess assembly language source files
and rename any affected symbols.
Experimental FIPS symbol renaming. Fixups under fips/ to make symbol renaming work.
2011-02-16 14:49:50 +00:00
[Steve Henson]
Add non-FIPS algorithm blocking and selftest checking.
2011-02-15 16:03:47 +00:00
*) Add selftest checks and algorithm block of non-fips algorithms in
FIPS mode. Remove DES2 from selftests.
[Steve Henson]
Add ECDSA functionality to fips module. Initial very incomplete version of algorithm test program.
2011-02-14 17:14:55 +00:00
*) Add ECDSA code to fips module. Add tiny fips_ecdsa_check to just
return internal method without any ENGINE dependencies. Add new

2011-02-15 16:03:47 +00:00
tiny fips sign and verify functions.
Add ECDSA functionality to fips module. Initial very incomplete version of algorithm test program.
2011-02-14 17:14:55 +00:00
[Steve Henson]
New option to disable characteristic two fields in EC code.
2011-02-12 17:23:32 +00:00
*) New build option no-ec2m to disable characteristic 2 code.
[Steve Henson]
New "fispcanisteronly" build option: only build fipscanister.o and associated utilities. This functionality will be used by the validated tarball.
2011-02-11 19:02:34 +00:00
*) New build option "fipscanisteronly". This only builds fipscanister.o
and (currently) associated fips utilities. Uses the file Makefile.fips
instead of Makefile.org as the prototype.
[Steve Henson]
Add GCM IV generator. Add some FIPS restrictions to GCM. Update fips_gcmtest.
2011-02-09 16:21:43 +00:00
*) Add some FIPS mode restrictions to GCM. Add internal IV generator.
Update fips_gcmtest to use IV generator.
[Steve Henson]
Initial *very* experimental EVP support for AES-GCM. Note: probably very broken and subject to change.
2011-02-07 18:16:33 +00:00
*) Initial, experimental EVP support for AES-GCM. AAD can be input by
setting output buffer to NULL. The *Final function must be
called although it will not retrieve any additional data. The tag
can be set or retrieved with a ctrl. The IV length is by default 12
bytes (96 bits) but can be set to an alternative value. If the IV
length exceeds the maximum IV length (currently 16 bytes) it cannot be
set before the key.
[Steve Henson]
New flags EVP_CIPH_FLAG_CUSTOM_CIPHER in cipher structures if an underlying cipher handles all cipher symantics itself.
2011-02-07 14:36:08 +00:00
*) New flag in ciphers: EVP_CIPH_FLAG_CUSTOM_CIPHER. This means the
underlying do_cipher function handles all cipher semantics itself
including padding and finalisation. This is useful if (for example)
an ENGINE cipher handles block padding itself. The behaviour of
do_cipher is subtly changed if this flag is set: the return value
is the number of characters written to the output buffer (zero is
no longer an error code) or a negative error code. Also if the
Use 0 not -1 (since type is size_t) for finalisation argument to do_cipher: the NULL value for the input buffer is sufficient to notice this case.
2011-02-07 18:04:27 +00:00
input buffer is NULL and length 0 finalisation should be performed.
New flags EVP_CIPH_FLAG_CUSTOM_CIPHER in cipher structures if an underlying cipher handles all cipher symantics itself.
2011-02-07 14:36:08 +00:00
[Steve Henson]
avoid verification loops in trusted store when path building
2010-12-25 20:45:59 +00:00
*) If a candidate issuer certificate is already part of the constructed
path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case.
[Steve Henson]
For better forward-security support, add functions SSL_[CTX_]set_not_resumable_session_callback. Submitted by: Emilia Kasper (Google) [A part of this change affecting ssl/s3_lib.c was accidentally commited separately, together with a compilation fix for that file; see s3_lib.c CVS revision 1.133 (http://cvs.openssl.org/chngview?cn=19855).]
2010-08-26 15:15:47 +00:00
*) Improve forward-security support: add functions
void SSL_CTX_set_not_resumable_session_callback(SSL_CTX *ctx, int (*cb)(SSL *ssl, int is_forward_secure))
void SSL_set_not_resumable_session_callback(SSL *ssl, int (*cb)(SSL *ssl, int is_forward_secure))
for use by SSL/TLS servers; the callback function will be called whenever a
new session is created, and gets to decide whether the session may be
cached to make it resumable (return 0) or not (return 1). (As by the
SSL/TLS protocol specifications, the session_id sent by the server will be
empty to indicate that the session is not resumable; also, the server will
not generate RFC 4507 (RFC 5077) session tickets.)
A simple reasonable callback implementation is to return is_forward_secure.
This parameter will be set to 1 or 0 depending on the ciphersuite selected
by the SSL/TLS server library, indicating whether it can provide forward
security.
[Emilia K<>sper <emilia.kasper@esat.kuleuven.be> (Google)]
Add Next Protocol Negotiation.
2010-07-28 10:06:55 +00:00
*) Add Next Protocol Negotiation,
http://tools.ietf.org/html/draft-agl-tls-nextprotoneg-00. Can be
disabled with a no-npn flag to config or Configure. Code donated
by Google.
[Adam Langley <agl@google.com> and Ben Laurie]
new function to diff tm structures
2010-04-15 13:25:26 +00:00
*) New function OPENSSL_gmtime_diff to find the difference in days
and seconds between two tm structures. This will be used to provide
additional functionality for ASN1_TIME.
[Steve Henson]
In ssl3_clear, preserve s3->init_extra along with s3->rbuf. Submitted by: Bob Buckholz <bbuckholz@google.com>
2011-10-13 13:05:58 +00:00
*) Add -trusted_first option which attempts to find certificates in the
trusted store even if an untrusted chain is also supplied.
[Steve Henson]
*) Initial experimental support for explicitly trusted non-root CAs.
OpenSSL still tries to build a complete chain to a root but if an
intermediate CA has a trust setting included that is used. The first
setting is used: whether to trust or reject.
[Steve Henson]
*) New -verify_name option in command line utilities to set verification
parameters by name.
[Steve Henson]
*) Initial CMAC implementation. WARNING: EXPERIMENTAL, API MAY CHANGE.
Add CMAC pkey methods.

browses /reneg connection is renegotiated. If /renegcert it is
renegotiated requesting a certificate.
[Steve Henson]
*) Add an "external" session cache for debugging purposes to s_server. This
should help trace issues which normally are only apparent in deployed
multi-process servers.
[Steve Henson]
*) Extensive audit of libcrypto with DEBUG_UNUSED. Fix many cases where
return value is ignored. NB. The functions RAND_add(), RAND_seed(),
BIO_set_cipher() and some obscure PEM functions were changed so they
can now return an error. The RAND changes required a change to the
RAND_METHOD structure.
[Steve Henson]
*) New macro __owur for "OpenSSL Warn Unused Result". This makes use of
a gcc attribute to warn if the result of a function is ignored. This
is enable if DEBUG_UNUSED is set. Add to several functions in evp.h
whose return value is often ignored.
[Steve Henson]
Changes between 1.0.0f and 1.0.1 [xx XXX xxxx]
Improve optional 64-bit NIST-P224 implementation, and add NIST-P256 and NIST-P521. (Now -DEC_NISTP_64_GCC_128 enables all three of these; -DEC_NISTP224_64_GCC_128 no longer works.) Submitted by: Google Inc.
2011-10-18 19:43:16 +00:00
*) Add optional 64-bit optimized implementations of elliptic curves NIST-P224,
NIST-P256, NIST-P521, with constant-time single point multiplication on
typical inputs. Compiler support for the nonstandard type __uint128_t is

[Steve Henson]
RSA PSS verification support including certificates and certificate requests. Add new ASN1 signature initialisation function to handle this case.
2010-03-08 18:10:35 +00:00
*) Add new algorithm specific ASN1 verification initialisation function
to EVP_PKEY_ASN1_METHOD: this is not in EVP_PKEY_METHOD since the ASN1
handling will be the same no matter what EVP_PKEY_METHOD is used.
Add a PSS handler to support verification of PSS signatures: checked
against a number of sample certificates.

- Fix a bug that suppressed issuing of a new ticket if the client
presented a ticket with an expired session.
- Try to set the ticket lifetime hint to something reasonable.
- Make tickets shorter by excluding irrelevant information.
- On the client side, don't ignore renewed tickets.

Synchronize with 1.0.1 CHANGES file.
2011-09-05 09:30:50 +00:00
*) Add GCM support to TLS library. Some custom code is needed to split
the IV between the fixed (from PRF) and explicit (from TLS record)
portions. This adds all GCM ciphersuites supported by RFC5288 and
RFC5289. Generalise some AES* cipherstrings to inlclude GCM and
add a special AESGCM string for GCM only.
[Steve Henson]
*) Expand range of ctrls for AES GCM. Permit setting invocation
field on decrypt and retrieval of invocation field only on encrypt.
[Steve Henson]
*) Add HMAC ECC ciphersuites from RFC5289. Include SHA384 PRF support.
As required by RFC5289 these ciphersuites cannot be used if for
versions of TLS earlier than 1.2.
[Steve Henson]
*) For FIPS capable OpenSSL interpret a NULL default public key method
as unset and return the appopriate default but do *not* set the default.
This means we can return the appopriate method in applications that
swicth between FIPS and non-FIPS modes.
[Steve Henson]
Fix the version history: changes going into 1.1.0 that are also going into 1.0.1 should not be listed as "changes between 1.0.1 and 1.0.0". This makes the OpenSSL_1_0_1-stable and HEAD versions of this file consistent with each other (the HEAD version has the additional 1.1.0 section, but doesn't otherwise differ).
2011-06-15 14:49:17 +00:00
*) Redirect HMAC and CMAC operations to FIPS module in FIPS mode. If an
ENGINE is used then we cannot handle that in the FIPS module so we
keep original code iff non-FIPS operations are allowed.
[Steve Henson]
*) Add -attime option to openssl verify.
[Peter Eckersley <pde@eff.org> and Ben Laurie]
*) Redirect DSA and DH operations to FIPS module in FIPS mode.
[Steve Henson]
*) Redirect ECDSA and ECDH operations to FIPS module in FIPS mode. Also use
FIPS EC methods unconditionally for now.
[Steve Henson]
*) New build option no-ec2m to disable characteristic 2 code.
[Steve Henson]
*) Backport libcrypto audit of return value checking from 1.1.0-dev; not
all cases can be covered as some introduce binary incompatibilities.
[Steve Henson]
*) Redirect RSA operations to FIPS module including keygen,
encrypt, decrypt, sign and verify. Block use of non FIPS RSA methods.
[Steve Henson]
*) Add similar low level API blocking to ciphers.
[Steve Henson]
*) Low level digest APIs are not approved in FIPS mode: any attempt
to use these will cause a fatal error. Applications that *really* want
to use them can use the private_* version instead.
[Steve Henson]
*) Redirect cipher operations to FIPS module for FIPS builds.
[Steve Henson]
*) Redirect digest operations to FIPS module for FIPS builds.
[Steve Henson]
*) Update build system to add "fips" flag which will link in fipscanister.o
for static and shared library builds embedding a signature if needed.
[Steve Henson]
*) Output TLS supported curves in preference order instead of numerical
order. This is currently hardcoded for the highest order curves first.
This should be configurable so applications can judge speed vs strength.
[Steve Henson]
*) Add TLS v1.2 server support for client authentication.
[Steve Henson]
*) Add support for FIPS mode in ssl library: disable SSLv3, non-FIPS ciphers
and enable MD5.
[Steve Henson]
*) Functions FIPS_mode_set() and FIPS_mode() which call the underlying
FIPS modules versions.
[Steve Henson]
*) Add TLS v1.2 client side support for client authentication. Keep cache
of handshake records longer as we don't know the hash algorithm to use
until after the certificate request message is received.
[Steve Henson]
*) Initial TLS v1.2 client support. Add a default signature algorithms
extension including all the algorithms we support. Parse new signature
format in client key exchange. Relax some ECC signing restrictions for
TLS v1.2 as indicated in RFC5246.
[Steve Henson]
*) Add server support for TLS v1.2 signature algorithms extension. Switch
to new signature format when needed using client digest preference.
All server ciphersuites should now work correctly in TLS v1.2. No client
support yet and no support for client certificates.
[Steve Henson]
*) Initial TLS v1.2 support. Add new SHA256 digest to ssl code, switch
to SHA256 for PRF when using TLS v1.2 and later. Add new SHA256 based
ciphersuites. At present only RSA key exchange ciphersuites work with
TLS v1.2. Add new option for TLS v1.2 replacing the old and obsolete
SSL_OP_PKCS1_CHECK flags with SSL_OP_NO_TLSv1_2. New TLSv1.2 methods
and version checking.
[Steve Henson]
*) New option OPENSSL_NO_SSL_INTERN. If an application can be compiled
with this defined it will not be affected by any changes to ssl internal
structures. Add several utility functions to allow openssl application
to work with OPENSSL_NO_SSL_INTERN defined.
[Steve Henson]
*) Add SRP support.

This also avoids the need to obtain the CRYPTO_LOCK_RSA_BLINDING

BN_BLINDING_update for each BN_BLINDING structure (previously,
the last update always remained unused).

to determine whether the BIO is the one explicitly called or as a result
of the ctrl being passed down the chain. Fix BIO_pop() and SSL BIOs so
it handles reference counts correctly and doesn't zero out the I/O bio
when it is not being explicitly popped. WARNING: applications which
included workarounds for the old buggy behaviour will need to be modified

[Steve Henson]
Update from 1.0.0-stable
2009-04-08 16:16:35 +00:00
*) If no SSLv2 ciphers are used don't use an SSLv2 compatible client hello:
this allows the use of compression and extensions. Change default cipher
string to remove SSLv2 ciphersuites. This effectively avoids ancient SSLv2
by default unless an application cipher string requests it.
[Steve Henson]
Merge from 1.0.0-stable branch.
2009-04-03 11:45:19 +00:00
*) Alter match criteria in PKCS12_parse(). It used to try to use local
key ids to find matching certificates and keys but some PKCS#12 files
don't follow the (somewhat unwritten) rules and this strategy fails.
Now just gather all certificates together and the first private key
then look for the first certificate that matches the key.
[Steve Henson]
Allow use of algorithm and cipher names for dgsts and enc utilities instead of having to manually include each one.
2009-03-30 11:31:50 +00:00
*) Support use of registered digest and cipher names for dgst and cipher
commands instead of having to add each one as a special case. So now
you can do:
openssl sha256 foo
as well as:
openssl dgst -sha256 foo
and this works for ENGINE based algorithms too.

Update certificate hash line format to handle canonical format and avoid MD5 dependency.

2008-08-29 11:37:21 +00:00
*) Support for CRLs partitioned by reason code. Reorganise CRL processing
code and add additional score elements. Validate alternate CRL paths
as part of the CRL checking and indicate a new error "CRL path validation
error" in this case. Applications wanting additional details can use
the verify callback and check the new "parent" field. If this is not
NULL CRL path validation is taking place. Existing applications wont
see this because it requires extended CRL support which is off by
default.

Remove the dual-callback scheme for numeric and pointer thread IDs, deprecate the original (numeric-only) scheme, and replace with the CRYPTO_THREADID object. This hides the platform-specifics and should reduce the possibility for programming errors (where failing to explicitly check both thread ID forms could create subtle, platform-specific bugs). Thanks to Bodo, for invaluable review and feedback.
2008-08-06 15:54:15 +00:00
*) To cater for systems that provide a pointer-based thread ID rather
than numeric, deprecate the current numeric thread ID mechanism and
replace it with a structure and associated callback type. This
mechanism allows a numeric "hash" to be extracted from a thread ID in
either case, and on platforms where pointers are larger than 'long',
mixing is done to help ensure the numeric 'hash' is usable even if it
can't be guaranteed unique. The default mechanism is to use "&errno"
as a pointer-based thread ID to distinguish between threads.
Applications that want to provide their own thread IDs should now use
CRYPTO_THREADID_set_callback() to register a callback that will call
either CRYPTO_THREADID_set_numeric() or CRYPTO_THREADID_set_pointer().
Mention ERR_remove_state() deprecation, and ERR_remove_thread_state(NULL).
2008-08-13 19:30:01 +00:00
Note that ERR_remove_state() is now deprecated, because it is tied
to the assumption that thread IDs are numeric. ERR_remove_state(0)
to free the current thread's error state should be replaced by
ERR_remove_thread_state(NULL).
Remove the dual-callback scheme for numeric and pointer thread IDs, deprecate the original (numeric-only) scheme, and replace with the CRYPTO_THREADID object. This hides the platform-specifics and should reduce the possibility for programming errors (where failing to explicitly check both thread ID forms could create subtle, platform-specific bugs). Thanks to Bodo, for invaluable review and feedback.
2008-08-06 15:54:15 +00:00
(This new approach replaces the functions CRYPTO_set_idptr_callback(),
CRYPTO_get_idptr_callback(), and CRYPTO_thread_idptr() that existed in
OpenSSL 0.9.9-dev between June 2006 and August 2008. Also, if an
application was previously providing a numeric thread callback that
was inappropriate for distinguishing threads, then uniqueness might
have been obtained with &errno that happened immediately in the
intermediate development versions of OpenSSL; this is no longer the
case, the numeric thread callback will now override the automatic use
of &errno.)

1. Changes for s_client.c to make it return non-zero exit code in case of handshake failure 2. Changes to x509_certificate_type function (crypto/x509/x509type.c) to make it recognize GOST certificates as EVP_PKT_SIGN|EVP_PKT_EXCH (required for s3_srvr to accept GOST client certificates). 3. Changes to EVP - adding of function EVP_PKEY_CTX_get0_peerkey - Make function EVP_PKEY_derive_set_peerkey work for context with ENCRYPT operation, because we use peerkey field in the context to pass non-ephemeral secret key to GOST encrypt operation. - added EVP_PKEY_CTRL_SET_IV control command. It is really GOST-specific, but it is used in SSL code, so it has to go in some header file, available during libssl compilation 4. Fix to HMAC to avoid call of OPENSSL_cleanse on undefined data 5. Include des.h if KSSL_DEBUG is defined into some libssl files, to make debugging output which depends on constants defined there, work and other KSSL_DEBUG output fixes 6. Declaration of real GOST ciphersuites, two authentication methods SSL_aGOST94 and SSL_aGOST2001 and one key exchange method SSL_kGOST 7. Implementation of these methods. 8. Support for sending unsolicited serverhello extension if GOST ciphersuite is selected. It is require for interoperability with CryptoPro CSP 3.0 and 3.6 and controlled by SSL_OP_CRYPTOPRO_TLSEXT_BUG constant. This constant is added to SSL_OP_ALL, because it does nothing, if non-GOST ciphersuite is selected, and all implementation of GOST include compatibility with CryptoPro. 9. Support for CertificateVerify message without length field. It is another CryptoPro bug, but support is made unconditional, because it does no harm for draft-conforming implementation. 10. In tls1_mac extra copy of stream mac context is no more done. When I've written currently commited code I haven't read EVP_DigestSignFinal manual carefully enough and haven't noticed that it does an internal digest ctx copying. This implementation was tested against 1. CryptoPro CSP 3.6 client and server 2. Cryptopro CSP 3.0 server

Implement the Opaque PRF Input TLS extension (draft-rescorla-tls-opaque-prf-input-00.txt), and do some cleanups and bugfixes on the way. In particular, this fixes the buffer bounds checks in ssl_add_clienthello_tlsext() and in ssl_add_serverhello_tlsext(). Note that the opaque PRF Input TLS extension is not compiled by default; see CHANGES.
2007-09-21 06:54:24 +00:00
*) Implement Opaque PRF Input TLS extension as specified in
draft-rescorla-tls-opaque-prf-input-00.txt. Since this is not an
official specification yet and no extension type assignment by
IANA exists, this extension (for now) will have to be explicitly
enabled when building OpenSSL by providing the extension number
to use. For example, specify an option
-DTLSEXT_TYPE_opaque_prf_input=0x9527
to the "config" or "Configure" script to enable the extension,
assuming extension number 0x9527 (which is a completely arbitrary
and unofficial assignment based on the MD5 hash of the Internet
Draft). Note that by doing so, you potentially lose
interoperability with other TLS implementations since these might
be using the same extension number for other purposes.
SSL_set_tlsext_opaque_prf_input(ssl, src, len) is used to set the
opaque PRF input value to use in the handshake. This will create
an interal copy of the length-'len' string at 'src', and will
return non-zero for success.
To get more control and flexibility, provide a callback function
by using
SSL_CTX_set_tlsext_opaque_prf_input_callback(ctx, cb)
SSL_CTX_set_tlsext_opaque_prf_input_callback_arg(ctx, arg)
where
int (*cb)(SSL *, void *peerinput, size_t len, void *arg);
void *arg;
Callback function 'cb' will be called in handshakes, and is
expected to use SSL_set_tlsext_opaque_prf_input() as appropriate.
Argument 'arg' is for application purposes (the value as given to
SSL_CTX_set_tlsext_opaque_prf_input_callback_arg() will directly
be provided to the callback function). The callback function
has to return non-zero to report success: usually 1 to use opaque
PRF input just if possible, or 2 to enforce use of the opaque PRF
input. In the latter case, the library will abort the handshake
if opaque PRF input is not successfully negotiated.
Arguments 'peerinput' and 'len' given to the callback function
will always be NULL and 0 in the case of a client. A server will
see the client's opaque PRF input through these variables if
available (NULL and 0 otherwise). Note that if the server
provides an opaque PRF input, the length must be the same as the
length of the client's opaque PRF input.
Note that the callback function will only be called when creating
a new session (session resumption can resume whatever was
previously negotiated), and will not be called in SSL 2.0
handshakes; thus, SSL_CTX_set_options(ctx, SSL_OP_NO_SSLv2) or
SSL_set_options(ssl, SSL_OP_NO_SSLv2) is especially recommended
for applications that need to enforce opaque PRF input.

Improve ciphersuite order stability when disabling ciphersuites. Change ssl_create_cipher_list() to prefer ephemeral ECDH over ephemeral DH.
2007-02-20 16:36:58 +00:00
*) Change ssl_cipher_apply_rule(), the internal function that does
the work each time a ciphersuite string requests enabling
("foo+bar"), moving ("+foo+bar"), disabling ("-foo+bar", or
removing ("!foo+bar") a class of ciphersuites: Now it maintains
the order of disabled ciphersuites such that those ciphersuites
that most recently went from enabled to disabled not only stay
in order with respect to each other, but also have higher priority
than other disabled ciphersuites the next time ciphersuites are
enabled again.
This means that you can now say, e.g., "PSK:-PSK:HIGH" to enable
the same ciphersuites as with "HIGH" alone, but in a specific
order where the PSK ciphersuites come first (since they are the
most recently disabled ciphersuites when "HIGH" is parsed).
Also, change ssl_create_cipher_list() (using this new
funcionality) such that between otherwise identical
cihpersuites, ephemeral ECDH is preferred over ephemeral DH in
the default order.
[Bodo Moeller]
Include "!eNULL" in SSL_DEFAULT_CIPHER_LIST to make sure that a ciphersuite string such as "DEFAULT:RSA" cannot enable authentication-only ciphersuites. Also, change ssl_create_cipher_list() so that it no longer starts with an arbitrary ciphersuite ordering, but instead uses the logic that we previously had in SSL_DEFEAULT_CIPHER_LIST. SSL_DEFAULT_CIPHER_LIST simplifies into just "ALL:!aNULL:!eNULL".
2007-02-19 18:41:41 +00:00
*) Change ssl_create_cipher_list() so that it automatically
arranges the ciphersuites in reasonable order before starting
to process the rule string. Thus, the definition for "DEFAULT"
(SSL_DEFAULT_CIPHER_LIST) now is just "ALL:!aNULL:!eNULL", but
remains equivalent to "AES:ALL:!aNULL:!eNULL:+aECDH:+kRSA:+RC4:@STRENGTH".
This makes it much easier to arrive at a reasonable default order
in applications for which anonymous ciphers are OK (meaning
that you can't actually use DEFAULT).
[Bodo Moeller; suggested by Victor Duchovni]
Reorganize the data used for SSL ciphersuite pattern matching. This change resolves a number of problems and obviates multiple kludges. A new feature is that you can now say "AES256" or "AES128" (not just "AES", which enables both). In some cases the ciphersuite list generated from a given string is affected by this change. I hope this is just in those cases where the previous behaviour did not make sense.
2007-02-17 06:45:38 +00:00
*) Split the SSL/TLS algorithm mask (as used for ciphersuite string
processing) into multiple integers instead of setting
"SSL_MKEY_MASK" bits, "SSL_AUTH_MASK" bits, "SSL_ENC_MASK",
"SSL_MAC_MASK", and "SSL_SSL_MASK" bits all in a single integer.
(These masks as well as the individual bit definitions are hidden
away into the non-exported interface ssl/ssl_locl.h, so this
change to the definition of the SSL_CIPHER structure shouldn't
affect applications.) This give us more bits for each of these
categories, so there is no longer a need to coagulate AES128 and
AES256 into a single algorithm bit, and to coagulate Camellia128
and Camellia256 into a single algorithm bit, which has led to all
kinds of kludges.
Thus, among other things, the kludge introduced in 0.9.7m and
0.9.8e for masking out AES256 independently of AES128 or masking
out Camellia256 independently of AES256 is not needed here in 0.9.9.
With the change, we also introduce new ciphersuite aliases that
so far were missing: "AES128", "AES256", "CAMELLIA128", and
"CAMELLIA256".

Experimental streaming PKCS#7 support. I thought it was about time I dusted this off. This stuff had been sitting on my hard drive for *ages* (2003 in fact). Hasn't been tested well and may not work properly. Nothing uses it at present which is just as well. Think of this as a traditional Christmas present which looks far more impressive in the adverts and on the box, some of the bits are missing and falls to bits if you play with it too much.

Tidy up CRL handling by checking for critical extensions when it is loaded. Add new function X509_CRL_get0_by_serial() to lookup a revoked entry to avoid the need to access the structure directly. Add new X509_CRL_METHOD to allow common CRL operations (verify, lookup) to be redirected.
2006-09-21 12:42:15 +00:00

new CRLs added to a directory can be used. New command line option
-verify_return_error to s_client and s_server. This causes real errors
to be returned by the verify callback instead of carrying on no matter
what. This reflects the way a "real world" verify callback would behave.

partitioned by DP are handled but no indirect CRL or reason partitioning
(yet). Complete overhaul of CRL handling: now the most suitable CRL is
selected via a scoring technique which handles IDP and AKID in CRLs.
[Steve Henson]
*) New X509_STORE_CTX callbacks lookup_crls() and lookup_certs() which
will ultimately be used for all verify operations: this will remove the
X509_STORE dependency on certificate verification and allow alternative

[Steve Henson]
Cache some CRL related extensions.
2006-07-24 12:39:22 +00:00

this would be called X509_CRL_cmp() but that name is already used by
a function that just compares CRL issuer names. Cache several CRL
extensions in X509_CRL structure and cache CRLDP in X509.

Store canonical encodings of Name structures. Update X509_NAME_cmp() to use them.
2006-07-18 12:36:19 +00:00

Change array representation of binary polynomials to make GF2m part of the BN library more generally useful. Submitted by: Douglas Stebila
2006-06-18 22:00:57 +00:00
*) Change the array representation of binary polynomials: the list
of degrees of non-zero coefficients is now terminated with -1.
Previously it was terminated with 0, which was also part of the
value; thus, the array representation was not applicable to
polynomials where t^0 has coefficient zero. This change makes
the array representation useful in a more general context.

Ciphersuite string bugfixes, and ECC-related (re-)definitions.
2006-06-14 17:40:31 +00:00
*) Various modifications and fixes to SSL/TLS cipher string
handling. For ECC, the code now distinguishes between fixed ECDH
with RSA certificates on the one hand and with ECDSA certificates
on the other hand, since these are separate ciphersuites. The
unused code for Fortezza ciphersuites has been removed.
For consistency with EDH, ephemeral ECDH is now called "EECDH"
(not "ECDHE"). For consistency with the code for DH
certificates, use of ECDH certificates is now considered ECDH
authentication, not RSA or ECDSA authentication (the latter is
merely the CA's signing algorithm and not actively used in the
protocol).
The temporary ciphersuite alias "ECCdraft" is no longer
available, and ECC ciphersuites are no longer excluded from "ALL"
and "DEFAULT". The following aliases now exist for RFC 4492
ciphersuites, most of these by analogy with the DH case:
kECDHr - ECDH cert, signed with RSA
kECDHe - ECDH cert, signed with ECDSA
kECDH - ECDH cert (signed with either RSA or ECDSA)
kEECDH - ephemeral ECDH
ECDH - ECDH cert or ephemeral ECDH
aECDH - ECDH cert
aECDSA - ECDSA cert
ECDSA - ECDSA cert
AECDH - anonymous ECDH
EECDH - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH")

2006-05-08 12:44:25 +00:00
*) Update PKCS#7 enveloped data routines to use new API. This is now
supported by any public key method supporting the encrypt operation. A
ctrl is added to allow the public key algorithm to examine or modify
the PKCS#7 RecipientInfo structure if it needs to: for RSA this is
a no op.
[Steve Henson]
Version changes where needed.
2005-05-18 04:04:12 +00:00
Add support for default public key digest type ctrl.
2006-05-07 17:09:39 +00:00
*) Add a ctrl to asn1 method to allow a public key algorithm to express
a default digest type to use. In most cases this will be SHA1 but some
algorithms (such as GOST) need to specify an alternative digest. The
return value indicates how strong the prefernce is 1 means optional and
2 is mandatory (that is it is the only supported type). Modify
ASN1_item_sign() to accept a NULL digest argument to indicate it should
use the default md. Update openssl utilities to use the default digest
type for signing if it is not explicitly indicated.
[Steve Henson]
Remove link between digests and signature algorithms. Use cross reference table in ASN1_item_sign(), ASN1_item_verify() to eliminate the need for algorithm specific code.
2006-04-19 17:05:59 +00:00
*) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New
EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant
signing method from the key type. This effectively removes the link
between digests and public key types.
[Steve Henson]
Add OID cross reference table. Fix some typos in GOST OIDs. Update dependencies.
2006-04-18 23:36:07 +00:00
*) Add an OID cross reference table and utility functions. Its purpose is to
translate between signature OIDs such as SHA1WithrsaEncryption and SHA1,
rsaEncryption. This will allow some of the algorithm specific hackery
needed to use the correct OID to be removed.
[Steve Henson]

TLS clients will continue a connection gracefully when they receive

waiting for a server hello which it will never receive. Now we treat a

2008-09-14 13:51:44 +00:00
*) Partial backport from 0.9.9-dev:
Introduce bn_mul_mont (dedicated Montgomery multiplication
procedure) as a candidate for BIGNUM assembler implementation.
While 0.9.9-dev uses assembler for various architectures, only
x86_64 is available by default here in the 0.9.8 branch, and
32-bit x86 is available through a compile-time setting.
To try the 32-bit x86 assembler implementation, use Configure
option "enable-montasm" (which exists only for this backport).
As "enable-montasm" for 32-bit x86 disclaims code stability
anyway, in this constellation we activate additional code
backported from 0.9.9-dev for further performance improvements,
namely BN_from_montgomery_word. (To enable this otherwise,
e.g. x86_64, try "-DMONT_FROM_WORD___NON_DEFAULT_0_9_8_BUILD".)

This was broken until now in 0.9.8 releases, such that the only way
a registered ENGINE could be used (assuming it initialises
successfully on the host) was to explicitly set it as the default
for the relevant algorithms. This is in contradiction with 0.9.7
behaviour and the documentation. With this fix, when an ENGINE is
registered into a given algorithm's table of implementations, the
'uptodate' flag is reset so that auto-discovery will be used next
time a new context for that algorithm attempts to select an
implementation.

*) Add RFC4507 support to OpenSSL. This includes the corrections in
RFC4507bis. The encrypted ticket format is an encrypted encoded
SSL_SESSION structure, that way new session features are automatically
supported.
If a client application caches session in an SSL_SESSION structure
support is transparent because tickets are now stored in the encoded
SSL_SESSION.
The SSL_CTX structure automatically generates keys for ticket
protection in servers so again support should be possible
with no application modification.
If a client or server wishes to disable RFC4507 support then the option
SSL_OP_NO_TICKET can be set.
Add a TLS extension debugging callback to allow the contents of any client
or server extensions to be examined.

[Steve Henson]
*) Add initial support for TLS extensions, specifically for the server_name

stored in that context to allow for session resumption, even after the
SSL has been switched to a new SSL_CTX in reaction to a client's
server_name extension.

testing the HostName extension for a specific single host name ('-cert'

negotiation). If the unrecogninzed_name alert has to be sent, this by

BN_FLG_CONSTTIME is the new name for the previous
BN_FLG_EXP_CONSTTIME flag, since it now affects more than just
modular exponentiation. (Since OpenSSL 0.9.7h, setting this flag
in the exponent causes BN_mod_exp_mont() to use the alternative
implementation in BN_mod_exp_mont_consttime().) The old name
remains as a deprecated alias.
Similary, RSA_FLAG_NO_EXP_CONSTTIME is replaced by a more general
RSA_FLAG_NO_CONSTTIME flag since the RSA implementation now uses
constant-time implementations for more than just exponentiation.
Here too the old name is kept as a deprecated alias.
BN_BLINDING_new() will now use BN_dup() for the modulus so that
the BN_BLINDING structure gets an independent copy of the
modulus. This means that the previous "BIGNUM *m" argument to
BN_BLINDING_new() and to BN_BLINDING_create_param() now
essentially becomes "const BIGNUM *m", although we can't actually
change this in the header file before 0.9.9. It allows
RSA_setup_blinding() to use BN_with_flags() on the modulus to
enable BN_FLG_CONSTTIME.

stricter session ID context matching
2007-03-21 14:33:16 +00:00
*) In the SSL/TLS server implementation, be strict about session ID
context matching (which matters if an application uses a single
external cache for different purposes). Previously,
out-of-context reuse was forbidden only if SSL_VERIFY_PEER was
set. This did ensure strict client verification, but meant that,
with applications using a single external cache for quite
different requirements, clients could circumvent ciphersuite
restrictions for a given session ID context by starting a session
in a different context.

Changes between 0.9.8d and 0.9.8e [23 Feb 2007]
Reorganize the data used for SSL ciphersuite pattern matching. This change resolves a number of problems and obviates multiple kludges. A new feature is that you can now say "AES256" or "AES128" (not just "AES", which enables both). In some cases the ciphersuite list generated from a given string is affected by this change. I hope this is just in those cases where the previous behaviour did not make sense.
2007-02-17 06:45:38 +00:00
*) Since AES128 and AES256 (and similarly Camellia128 and
Camellia256) share a single mask bit in the logic of
ssl/ssl_ciph.c, the code for masking out disabled ciphers needs a
kludge to work properly if AES128 is available and AES256 isn't
(or if Camellia128 is available and Camellia256 isn't).

(within i2d_ECPrivateKey, i2d_ECPKParameters, i2d_ECParameters):
When a point or a seed is encoded in a BIT STRING, we need to
prevent the removal of trailing zero bits to get the proper DER
encoding. (By default, crypto/asn1/a_bitstr.c assumes the case
of a NamedBitList, for which trailing 0 bits need to be removed.)

ensure that ciphersuite strings such as "RC4-MD5" match the SSL 2.0 ciphersuite as well
2006-09-11 09:49:03 +00:00
*) Since 0.9.8b, ciphersuite strings naming explicit ciphersuites
match only those. Before that, "AES256-SHA" would be interpreted
Update
2006-09-12 14:42:19 +00:00
as a pattern and match "AES128-SHA" too (since AES128-SHA got
the same strength classification in 0.9.7h) as we currently only
ensure that ciphersuite strings such as "RC4-MD5" match the SSL 2.0 ciphersuite as well
2006-09-11 09:49:03 +00:00
have a single AES bit in the ciphersuite description bitmap.
That change, however, also applied to ciphersuite strings such as
"RC4-MD5" that intentionally matched multiple ciphersuites --
namely, SSL 2.0 ciphersuites in addition to the more common ones
from SSL 3.0/TLS 1.0.
So we change the selection algorithm again: Naming an explicit
ciphersuite selects this one ciphersuite, and any other similar
ciphersuite (same bitmap) from *other* protocol versions.
Thus, "RC4-MD5" again will properly select both the SSL 2.0
ciphersuite and the SSL 3.0/TLS 1.0 ciphersuite.
Since SSL 2.0 does not have any ciphersuites for which the
128/256 bit distinction would be relevant, this works for now.
The proper fix will be to use different bits for AES128 and
AES256, which would have avoided the problems from the beginning;
however, bits are scarce, so we can only do this in a new release
(not just a patchlevel) when we can change the SSL_CIPHER
definition to split the single 'unsigned long mask' bitmap into
multiple values to extend the available space.

Reduce header interdependencies, initially in engine.h (the rest of the changes are the fallout). As this could break source code that doesn't directly include headers for interfaces it uses, changes to recursive includes are covered by the OPENSSL_NO_DEPRECATED symbol. It's better to define this when building and using openssl, and then adapt code where necessary - this is how to stay current. However the mechanism exists for the lethargic.

*) Reduced header interdepencies by declaring more opaque objects in

this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always,
developers should define this symbol when building and using openssl to
ensure they track the recommended behaviour, interfaces, [etc], but
backwards-compatible behaviour prevails when this isn't defined.

Enhance EVP code to generate random symmetric keys of the appropriate form, for example correct DES parity. Update S/MIME code and EVP_SealInit to use new functions. PR: 700
2004-03-28 17:38:00 +00:00
*) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality.
This will generate a random key of the appropriate length based on the
cipher context. The EVP_CIPHER can provide its own random key generation
routine to support keys of a specific form. This is used in the des and
3des routines to generate a key of the correct parity. Update S/MIME
code to use new functions and hence generate correct parity DES keys.
Add EVP_CHECK_DES_KEY #define to return an error if the key is not
valid (weak or incorrect parity).

Replace the BN_CTX implementation with my current work. I'm leaving the little TODO list in there as well as the debugging code (only enabled if BN_CTX_DEBUG is defined). I'd appreciate as much review and testing as can be spared for this. I'll commit some changes to other parts of the bignum code shortly to make better use of this implementation (no more fixed size limitations). Note also that under identical optimisations, I'm seeing a noticable speed increase over openssl-0.9.7 - so any feedback to confirm/deny this on other systems would also be most welcome.
2004-03-25 04:16:14 +00:00
*) Reimplemented the BN_CTX implementation. There is now no more static
limitation on the number of variables it can handle nor the depth of the
"stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack
information can now expand as required, and rather than having a single
static array of bignums, BN_CTX now uses a linked-list of such arrays
allowing it to expand on demand whilst maintaining the usefulness of
BN_CTX's "bundling".
[Geoff Thorpe]
By adding a BN_CTX parameter to the 'rsa_mod_exp' callback, private key operations no longer require two distinct BN_CTX structures. This may put more "strain" on the current BN_CTX implementation (which has a fixed limit to the number of variables it will hold), but so far this limit is not triggered by any of the tests pass and I will be changing BN_CTX in the near future to avoid this problem anyway. This also changes the default RSA implementation code to use the BN_CTX in favour of initialising some of its variables locally in each function.
2004-03-25 02:52:04 +00:00
*) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD
to allow all RSA operations to function using a single BN_CTX.

Convert openssl code not to assume the deprecated form of BN_zero(). Remove certain redundant BN_zero() initialisations, because BN_CTX_get(), BN_init(), [etc] already initialise to zero. Correct error checking in bn_sqr.c, and be less wishy-wash about how/why the result's 'top' value is set (note also, 'max' is always > 0 at this point).
2004-03-13 23:57:20 +00:00
*) BN_zero() only needs to set 'top' and 'neg' to zero for correct results,
and this should never fail. So the return value from the use of
BN_set_word() (which can fail due to needless expansion) is now deprecated;
if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro.
[Geoff Thorpe]
Document a change I'd already made, and at the same time, correct the change to work properly; BN_zero() should set 'neg' to zero as well as 'top' to match the behaviour of BN_new().

Put the first stage of my bignum debugging adventures into CVS. This code is itself experimental, and in addition may cause execution to break on existing openssl "bugs" that previously were harmless or at least invisible.
2003-11-04 22:54:49 +00:00
*) An audit of the BIGNUM code is underway, for which debugging code is
enabled when BN_DEBUG is defined. This makes stricter enforcements on what
is considered valid when processing BIGNUMs, and causes execution to
assert() when a problem is discovered. If BN_DEBUG_RAND is defined,
further steps are taken to deliberately pollute unused data in BIGNUM
structures to try and expose faulty code further on. For now, openssl will
(in its default mode of operation) continue to tolerate the inconsistent
forms that it has tolerated in the past, but authors and packagers should
consider trying openssl and their own applications when compiled with
these debugging symbols defined. It will help highlight potential bugs in
their own code, and will improve the test coverage for OpenSSL itself. At
some point, these tighter rules will become openssl's default to improve
maintainability, though the assert()s and other overheads will remain only
in debugging configurations. See bn.h for more details.
Document a change I'd already made, and at the same time, correct the change to work properly; BN_zero() should set 'neg' to zero as well as 'top' to match the behaviour of BN_new().

BN_CTX is opaque and the static initialiser BN_CTX_init() is not used except internally to the allocator BN_CTX_new(), as such this deprecates the use of BN_CTX_init() in the API. Moreover, the structure definition of BN_CTX is taken out of bn_lcl.h and moved into bn_ctx.c itself. NDEBUG should probably only be "forced" in the top-level configuration, but until it is I will avoid removing it from bn_ctx.c which might surprise people with massive slow-downs in their keygens. So I've left it in bn_ctx.c but tidied up the preprocessor logic a touch and made it more tolerant of debugging efforts.
2003-10-29 18:04:37 +00:00
*) BN_CTX_init() has been deprecated, as BN_CTX is an opaque structure
that can only be obtained through BN_CTX_new() (which implicitly
initialises it). The presence of this function only made it possible
to overwrite an existing structure (and cause memory leaks).
[Geoff Thorpe]
Relax some over-zealous constification that gave some lhash-based code no choice but to have to cast away "const" qualifiers from their prototypes. This does not remove constification restrictions from hash/compare callbacks, but allows destructor commands to be run over a tables' elements without bad casts.
2003-10-29 04:57:05 +00:00
*) Because of the callback-based approach for implementing LHASH as a
template type, lh_insert() adds opaque objects to hash-tables and
lh_doall() or lh_doall_arg() are typically used with a destructor callback
to clean up those corresponding objects before destroying the hash table
(and losing the object pointers). So some over-zealous constifications in
LHASH have been relaxed so that lh_insert() does not take (nor store) the
objects as "const" and the lh_doall[_arg] callback wrappers are not
prototyped to have "const" restrictions on the object pointers they are
given (and so aren't required to cast them away any more).
[Geoff Thorpe]
For whatever reason (compiler or header bugs), at least one commonly-used linux system (namely mine) chokes on our definitions and uses of the "HZ" symbol in crypto/tmdiff.[ch] and apps/speed.c as a "bad function cast" (when in fact there is no function casting involved at all). In both cases, it is easily worked around by not defining a cast into the macro and jiggling the expressions slightly. In addition - this highlights some cruft in openssl that needs sorting out. The tmdiff.h header is exported as part of the openssl API despite the fact that it is ugly as the driven sludge and not used anywhere in the library, applications, or utilities. More weird still, almost identical code exists in apps/speed.c though it looks to be slightly tweaked - so either tmdiff should be updated and used by speed.c, or it should be dumped because it's obviously not useful enough. Rather than removing it for now, I've changed the API for tmdiff to at least make sense. This involves taking the object type (MS_TM) from the implementation and using it in the header rather than using "char *" in the API and casting mercilessly in the code (ugh). If someone doesn't like "MS_TM" and the "ms_time_***" naming, by all means change it. This should be a harmless improvement, because the existing API is clearly not very useful (eg. we reimplement it rather than using it in our own utils). However, someone still needs to take a hack at consolidating speed.c and tmdiff.[ch] somehow.
2003-10-29 04:40:13 +00:00
*) The tmdiff.h API was so ugly and minimal that our own timing utility
(speed) prefers to use its own implementation. The two implementations
haven't been consolidated as yet (volunteers?) but the tmdiff API has had
its object type properly exposed (MS_TM) instead of casting to/from "char
*". This may still change yet if someone realises MS_TM and "ms_time_***"
aren't necessarily the greatest nomenclatures - but this is what was used
internally to the implementation so I've used that for now.

The default implementation of DSA_METHOD has an interdependence on the dsa_mod_exp() and bn_mod_exp() handlers from dsa_do_verify() and dsa_sign_setup(). When another DSA_METHOD implementation does not define these lower-level handlers, it becomes impossible to do a fallback to software on errors using a simple DSA_OpenSSL()->fn(key). This change allows the default DSA_METHOD to function in such circumstances by only using dsa_mod_exp() and bn_mod_exp() handlers if they exist, otherwise using BIGNUM implementations directly (which is what those handlers did before this change). There should be no noticable difference for the software case, or indeed any custom case that didn't already segfault, except perhaps that there is now one less level of indirection in all cases.

Rather than explicitly passing callback functions and caller-defined context data for the callbacks, a new structure BN_GENCB is defined that encapsulates this; a pointer to the structure is passed to all such functions instead. This wrapper structure allows the encapsulation of "old" and "new" style callbacks - "new" callbacks return a boolean result on the understanding that returning FALSE should terminate keygen/primality processing. The BN_GENCB abstraction will allow future callback modifications without needing to break binary compatibility nor change the API function prototypes. The new API functions have been given names ending in "_ex" and the old functions are implemented as wrappers to the new ones. The OPENSSL_NO_DEPRECATED symbol has been introduced so that, if defined, declaration of the older functions will be skipped. NB: Some openssl-internal code will stick with the older callbacks for now, so appropriate "#undef" logic will be put in place - this is in case the user is *building* openssl (rather than *including* its headers) with this symbol defined. There is another change in the new _ex functions; the key-generation functions do not return key structures but operate on structures passed by the caller, the return value is a boolean. This will allow for a smoother transition to having key-generation as "virtual function" in the various ***_METHOD tables.
2002-12-08 05:24:31 +00:00
*) Change the "progress" mechanism used in key-generation and
primality testing to functions that take a new BN_GENCB pointer in
place of callback/argument pairs. The new API functions have "_ex"
postfixes and the older functions are reimplemented as wrappers for
the new ones. The OPENSSL_NO_DEPRECATED symbol can be used to hide
declarations of the old functions to help (graceful) attempts to
migrate to the new functions. Also, the new key-generation API
functions operate on a caller-supplied key-structure and return
success/failure rather than returning a key or NULL - this is to
help make "keygen" another member function of RSA_METHOD etc.
document BN_GENCB API by adding an example
2003-01-13 13:44:20 +00:00
Example for using the new callback interface:
int (*my_callback)(int a, int b, BN_GENCB *cb) = ...;
void *my_arg = ...;
BN_GENCB my_cb;
BN_GENCB_set(&my_cb, my_callback, my_arg);
return BN_is_prime_ex(some_bignum, BN_prime_checks, NULL, &cb);
/* For the meaning of a, b in calls to my_callback(), see the
* documentation of the function that calls the callback.
* cb will point to my_cb; my_arg can be retrieved as cb->arg.
* my_callback should return 1 if it wants BN_is_prime_ex()
* to continue, or 0 to stop.

Various enhancements to PKCS#12 code, new medium level API, improved PKCS12_create and additional functionality in pkcs12 utility.
2002-10-03 23:53:52 +00:00
*) Add new 'medium level' PKCS#12 API. Certificates and keys
can be added using this API to created arbitrary PKCS#12
files while avoiding the low level API.
New options to PKCS12_create(), key or cert can be NULL and
will then be omitted from the output file. The encryption
algorithm NIDs can be set to -1 for no encryption, the mac
iteration count can be set to 0 to omit the mac.
Enhance pkcs12 utility by making the -nokeys and -nocerts
options work when creating a PKCS#12 file. New option -nomac
to omit the mac, NONE can be set for an encryption algorithm.
New code is modified to use the enhanced PKCS12_create()
instead of the low level API.

*) Add named elliptic curves over binary fields from X9.62, SECG,

[Sheueling Chang Shantz and Douglas Stebila
(Sun Microsystems Laboratories)]
*) Extend the EC library for elliptic curves over binary fields
(new files ec2_smpl.c, ec2_smpt.c, ec2_mult.c in crypto/ec/).
New EC_METHOD:
EC_GF2m_simple_method
New API functions:
EC_GROUP_new_curve_GF2m
EC_GROUP_set_curve_GF2m
EC_GROUP_get_curve_GF2m
EC_POINT_set_affine_coordinates_GF2m
EC_POINT_get_affine_coordinates_GF2m
EC_POINT_set_compressed_coordinates_GF2m
Point compression for binary fields is disabled by default for
patent reasons (compile with OPENSSL_EC_BIN_PT_COMP defined to
enable it).
As binary polynomials are represented as BIGNUMs, various members
of the EC_GROUP and EC_POINT data structures can be shared
between the implementations for prime fields and binary fields;
the above ..._GF2m functions (except for EX_GROUP_new_curve_GF2m)
are essentially identical to their ..._GFp counterparts.

2002-08-02 13:03:55 +00:00
*) Add binary polynomial arithmetic software in crypto/bn/bn_gf2m.c.
Polynomials are represented as BIGNUMs (where the sign bit is not
used) in the following functions [macros]:
BN_GF2m_add
BN_GF2m_sub [= BN_GF2m_add]
BN_GF2m_mod [wrapper for BN_GF2m_mod_arr]
BN_GF2m_mod_mul [wrapper for BN_GF2m_mod_mul_arr]
BN_GF2m_mod_sqr [wrapper for BN_GF2m_mod_sqr_arr]
BN_GF2m_mod_inv
BN_GF2m_mod_exp [wrapper for BN_GF2m_mod_exp_arr]
BN_GF2m_mod_sqrt [wrapper for BN_GF2m_mod_sqrt_arr]
BN_GF2m_mod_solve_quad [wrapper for BN_GF2m_mod_solve_quad_arr]
BN_GF2m_cmp [= BN_ucmp]
(Note that only the 'mod' functions are actually for fields GF(2^m).
BN_GF2m_add() is misnomer, but this is for the sake of consistency.)
For some functions, an the irreducible polynomial defining a
field can be given as an 'unsigned int[]' with strictly
decreasing elements giving the indices of those bits that are set;
i.e., p[] represents the polynomial
f(t) = t^p[0] + t^p[1] + ... + t^p[k]
where
p[0] > p[1] > ... > p[k] = 0.
This applies to the following functions:
BN_GF2m_mod_arr
BN_GF2m_mod_mul_arr
BN_GF2m_mod_sqr_arr
BN_GF2m_mod_inv_arr [wrapper for BN_GF2m_mod_inv]
BN_GF2m_mod_div_arr [wrapper for BN_GF2m_mod_div]
BN_GF2m_mod_exp_arr
BN_GF2m_mod_sqrt_arr
BN_GF2m_mod_solve_quad_arr
BN_GF2m_poly2arr
BN_GF2m_arr2poly
Conversion can be performed by the following functions:
BN_GF2m_poly2arr
BN_GF2m_arr2poly
bntest.c has additional tests for binary polynomial arithmetic.

Include "!eNULL" in SSL_DEFAULT_CIPHER_LIST to make sure that a ciphersuite string such as "DEFAULT:RSA" cannot enable authentication-only ciphersuites. Also, change ssl_create_cipher_list() so that it no longer starts with an arbitrary ciphersuite ordering, but instead uses the logic that we previously had in SSL_DEFEAULT_CIPHER_LIST. SSL_DEFAULT_CIPHER_LIST simplifies into just "ALL:!aNULL:!eNULL".
2007-02-19 18:41:41 +00:00
*) Include "!eNULL" in SSL_DEFAULT_CIPHER_LIST to make sure that
a ciphersuite string such as "DEFAULT:RSA" cannot enable

[Bodo Moeller]
Reorganize the data used for SSL ciphersuite pattern matching. This change resolves a number of problems and obviates multiple kludges. A new feature is that you can now say "AES256" or "AES128" (not just "AES", which enables both). In some cases the ciphersuite list generated from a given string is affected by this change. I hope this is just in those cases where the previous behaviour did not make sense.
2007-02-17 06:45:38 +00:00
*) Since AES128 and AES256 share a single mask bit in the logic of
ssl/ssl_ciph.c, the code for masking out disabled ciphers needs a
kludge to work properly if AES128 is available and AES256 isn't.

*) Use (SSL_RANDOM_VALUE - 4) bytes of pseudo random data when generating

(SSL_RANDOM_VALUE - sizeof(time_t)) would be used which would result in

This change has negligible security impact because:
1. Server and client random values still have 24 bytes of pseudo random
data.
2. Server and client random values are sent in the clear in the initial
handshake.
3. The master secret is derived using the premaster secret (48 bytes in
size for static RSA ciphersuites) as well as client server and random
values.

copies and compares OCSP nonces as opaque blobs without any attempt at
parsing them this should not create any compatibility issues.

own set of error texts inserted. The routines are there, just not

Option to disable SSL auto chain build
2003-02-12 17:06:02 +00:00
*) Allow an application to disable the automatic SSL chain building.
Before this a rather primitive chain build was always performed in
ssl3_output_cert_chain(): an application had no way to send the
correct chain if the automatic operation produced an incorrect result.
Now the chain builder is disabled if either:
1. Extra certificates are added via SSL_CTX_add_extra_chain_cert().
2. The mode flag SSL_MODE_NO_AUTO_CHAIN is set.
The reasoning behind this is that an application would not want the
auto chain building to take place if extra chain certificates are
present and it might also want a means of sending no additional
certificates (for example the chain has two certificates and the
root is omitted).

*) Remove most calls to EVP_CIPHER_CTX_cleanup() in evp_enc.c, this
allows existing EVP_CIPHER_CTX structures to be reused after
calling EVP_*Final(). This behaviour is used by encryption
BIOs and some applications. This has the side effect that
applications must explicitly clean up cipher contexts with
EVP_CIPHER_CTX_cleanup() or they will leak memory.

Since we provide two compatibility mappings, the user needs to
define the macro OPENSSL_DES_LIBDES_COMPATIBILITY if libdes
compatibility is desired. The default (i.e., when that macro
isn't defined) is OpenSSL 0.9.6c compatibility.
There are also macros that enable and disable the support of old
des functions altogether. Those are OPENSSL_ENABLE_OLD_DES_SUPPORT
and OPENSSL_DISABLE_OLD_DES_SUPPORT. If none or both of those
are defined, the default will apply: to support the old des routines.
In either case, one must include openssl/des.h to get the correct
definitions. Do not try to just include openssl/des_old.h, that
won't work.
Due to an increasing number of clashes between modern OpenSSL and libdes (which is still used out there) or other des implementations, the OpenSSL DES functions are renamed to begin with DES_ instead of des_. Compatibility routines are provided and declared by including openssl/des_old.h. Those declarations are the same as were in des.h when the OpenSSL project started, which is exactly how libdes looked at that time, and hopefully still looks today.

2001-10-01 15:56:25 +00:00
reduction of linker bloat, separation of pure "ENGINE" manipulation
(initialisation, etc) from functionality dealing with implementations
of specific crypto iterfaces. This change also introduces integrated
support for symmetric ciphers and digest implementations - so ENGINEs
can now accelerate these by providing EVP_CIPHER and EVP_MD
implementations of their own. This is detailed in crypto/engine/README
as it couldn't be adequately described here. However, there are a few
API changes worth noting - some RSA, DSA, DH, and RAND functions that
were changed in the original introduction of ENGINE code have now
reverted back - the hooking from this code to ENGINE is now a good
deal more passive and at run-time, operations deal directly with
RSA_METHODs, DSA_METHODs (etc) as they did before, rather than
dereferencing through an ENGINE pointer any more. Also, the ENGINE
functions dealing with BN_MOD_EXP[_CRT] handlers have been removed -
they were not being used by the framework as there is no concept of a
BIGNUM_METHOD and they could not be generalised to the new
'ENGINE_TABLE' mechanism that underlies the new code. Similarly,
ENGINE_cpy() has been removed as it cannot be consistently defined in
the new code.

functions. This change also alters the storage and management of global
ex_data state - it's now all inside ex_data.c and all "class" code (eg.
RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class
index counters. The API functions that use this state have been changed
to take a "class_index" rather than pointers to the class's local STACK
and counter, and there is now an API function to dynamically create new
classes. This centralisation allows us to (a) plug a lot of the
thread-safety problems that existed, and (b) makes it possible to clean
up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b)
such data would previously have always leaked in application code and
workarounds were in place to make the memory debugging turn a blind eye
to it. Application code that doesn't use this new function will still
leak as before, but their memory debugging output will announce it now
rather than letting it slide.

global state (2 LHASH tables and 2 locks) is only used by the "default"

the implementation prior to it being automatically set the first time
any other ERR function takes place. Ie. an application can call "get",
pass the return value to a module it has just loaded, and that module
can call its own "set" function using that value. This means the
module's "ERR" operations will use (and modify) the error state in the
application and not in its own statically linked copy of OpenSSL code.

operational state can be localised to each ENGINE structure, despite the
fact they all share the same "methods". New ENGINE structures returned in

declare their own commands (numbers), names (strings), descriptions,
and input types for run-time discovery by calling applications. A
subset of these commands are implicitly classed as "executable"
depending on their input type, and only these can be invoked through
the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this
can be based on user input, config files, etc). The distinction is
that "executable" commands cannot return anything other than a boolean
result and can only support numeric or string input, whereas some
discoverable commands may only be for direct use through
ENGINE_ctrl(), eg. supporting the exchange of binary data, function
pointers, or other custom uses. The "executable" commands are to
support parameterisations of ENGINE behaviour that can be
unambiguously defined by ENGINEs and used consistently across any
OpenSSL-based application. Commands have been added to all the
existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow
control over shared-library paths without source code alterations.

instead of the ASN1_ITEM structures themselves. This adds several
new macros which allow the underlying ASN1 function/structure to
be accessed transparently. As a result code should not use ASN1_ITEM
references directly (such as &X509_it) but instead use the relevant
macros (such as ASN1_ITEM_rptr(X509)). This option is to allow
use of the new ASN1 code on platforms where exporting structures
is problematical (for example in shared libraries) but exporting
functions returning pointers to structures is not.

the arbitrary values chosen for use as session IDs, particularly as it
can be useful for session caching in multiple-server environments. A
command-line switch for testing this (and any client code that wishes
to use such a feature) has been added to "s_server".

if it is explicitly trusted for OCSP signing. This is used to set
a root CA as a global signing root: that is any certificate that
chains to that CA is an acceptable OCSP signing certificate.

random devices, as specified by DEVRANDOM, until a sufficient amount
of data has been collected. We spend at most 10 ms on each file
(select timeout) and read in non-blocking mode. DEVRANDOM now
defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom"
(previously it was just the string "/dev/urandom"), so on typical
platforms the 10 ms delay will never occur.
Also separate out the Unix variant to its own file, rand_unix.c.
For VMS, there's a currently-empty rand_vms.c.
Change RAND_poll for Unix to try a number of devices and only read them for a short period of time (actually, poll them with select(), then read() whatever is there), which is about 10ms (hard-coded value) each.

provide utility functions which an application needing
to issue a request to an OCSP responder and analyse the
response will typically need: as opposed to those which an
OCSP responder itself would need which will be added later.
OCSP_request_sign() signs an OCSP request with an API similar
to PKCS7_sign(). OCSP_response_status() returns status of OCSP
response. OCSP_response_get1_basic() extracts basic response
from response. OCSP_resp_find_status(): finds and extracts status
information from an OCSP_CERTID structure (which will be created
when the request structure is built). These are built from lower
level functions which work on OCSP_SINGLERESP structures but
wont normally be used unless the application wishes to examine
extensions in the OCSP response for example.
Replace nonce routines with a pair of functions.
OCSP_request_add1_nonce() adds a nonce value and optionally
generates a random value. OCSP_check_nonce() checks the
validity of the nonce in an OCSP response.

ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN
uses the special reorder version of SET OF to sort the attributes
and reorder them to match the encoded order. This resolves a long
standing problem: a verify on a PKCS7 structure just after signing
it used to fail because the attribute order did not match the
encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes:
it uses the received order. This is necessary to tolerate some broken
software that does not order SET OF. This is handled by encoding
as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class)
to produce the required SET OF.

Fixes to OCSP print code. Don't try to print request certificates if signature is not present. Remove unnecessary test for certificates being NULL. Fix typos in printed output. Tidy up output. Fix for typo in OCSP_SERVICELOC ASN1 template. Also give a bit more info in CHANGES about the ASN1 revision.

completely replaces the old ASN1 functionality with a table driven
encoder and decoder which interprets an ASN1_ITEM structure describing
the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is
largely maintained. Almost all of the old asn1_mac.h macro based ASN1
has also been converted to the new form.
Merge from the ASN1 branch of new ASN1 code to main trunk. Lets see if the makes it to openssl-cvs :-)

Remove two bn_wexpand() from BN_mul(), which is a step toward getting BN_mul() correctly constified, avoids two realloc()'s that aren't really necessary and saves memory to boot.

Changes between 0.9.6i and 0.9.6j [10 Apr 2003]
*) Countermeasure against the Klima-Pokorny-Rosa extension of
Bleichbacher's attack on PKCS #1 v1.5 padding: treat
a protocol version number mismatch like a decryption error
in ssl3_get_client_key_exchange (ssl/s3_srvr.c).
[Bodo Moeller]
*) Turn on RSA blinding by default in the default implementation
to avoid a timing attack. Applications that don't want it can call
RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING.
They would be ill-advised to do so in most cases.
[Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller]
*) Change RSA blinding code so that it works when the PRNG is not
seeded (in this case, the secret RSA exponent is abused as
an unpredictable seed -- if it is not unpredictable, there
is no point in blinding anyway). Make RSA blinding thread-safe
by remembering the creator's thread ID in rsa->blinding and
having all other threads use local one-time blinding factors
(this requires more computation than sharing rsa->blinding, but
avoids excessive locking; and if an RSA object is not shared
between threads, blinding will still be very fast).

2002-11-27 12:24:05 +00:00
*) New function OPENSSL_cleanse(), which is used to cleanse a section of
memory from it's contents. This is done with a counter that will
place alternating values in each byte. This can be used to solve
two issues: 1) the removal of calls to memset() by highly optimizing
compilers, and 2) cleansing with other values than 0, since those can
be read through on certain media, for example a swap space on disk.

merely automatically cleared during the initial handshake.

2002-04-10 19:52:40 +00:00
*) Fix object definitions for Private and Enterprise: they were not
recognized in their shortname (=lowercase) representation. Extend
obj_dat.pl to issue an error when using undefined keywords instead
of silently ignoring the problem (Svenning Sorensen
<sss@sss.dnsalias.net>).
[Lutz Jaenicke]
*) Fix DH_generate_parameters() so that it works for 'non-standard'
generators, i.e. generators other than 2 and 5. (Previously, the
code did not properly initialise the 'add' and 'rem' values to
BN_generate_prime().)
In the new general case, we do not insist that 'generator' is
actually a primitive root: This requirement is rather pointless;
a generator of the order-q subgroup is just as good, if not
better.
[Bodo Moeller]
*) Map new X509 verification errors to alerts. Discovered and submitted by
Tom Wu <tom@arcot.com>.
[Lutz Jaenicke]
*) Fix ssl3_pending() (ssl/s3_lib.c) to prevent SSL_pending() from
returning non-zero before the data has been completely received
when using non-blocking I/O.
[Bodo Moeller; problem pointed out by John Hughes]
*) Some of the ciphers missed the strength entry (SSL_LOW etc).
[Ben Laurie, Lutz Jaenicke]
*) Fix bug in SSL_clear(): bad sessions were not removed (found by
Yoram Zahavi <YoramZ@gilian.com>).
[Lutz Jaenicke]
*) Add information about CygWin 1.3 and on, and preserve proper
configuration for the versions before that.
[Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
*) Make removal from session cache (SSL_CTX_remove_session()) more robust:
check whether we deal with a copy of a session and do not delete from
the cache in this case. Problem reported by "Izhar Shoshani Levi"
<izhar@checkpoint.com>.
[Lutz Jaenicke]
*) Do not store session data into the internal session cache, if it
is never intended to be looked up (SSL_SESS_CACHE_NO_INTERNAL_LOOKUP
flag is set). Proposed by Aslam <aslam@funk.com>.
[Lutz Jaenicke]
*) Have ASN1_BIT_STRING_set_bit() really clear a bit when the requested
value is 0.
[Richard Levitte]
*) [In 0.9.6d-engine release:]
Fix a crashbug and a logic bug in hwcrhk_load_pubkey().

Synchronize with 0.9.7-stable branch
2002-04-10 19:52:40 +00:00
*) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of
ssl3_accept (ssl/s3_srvr.c) incorrectly used a local flag
variable as an indication that a ClientHello message has been
received. As the flag value will be lost between multiple
invocations of ssl3_accept when using non-blocking I/O, the
function may not be aware that a handshake has actually taken
place, thus preventing a new session from being added to the
session cache.
To avoid this problem, we now set s->new_session to 2 instead of
using a local variable.
[Lutz Jaenicke, Bodo Moeller]
*) Bugfix: Return -1 from ssl3_get_server_done (ssl3/s3_clnt.c)
if the SSL_R_LENGTH_MISMATCH error is detected.
[Geoff Thorpe, Bodo Moeller]
*) New 'shared_ldflag' column in Configure platform table.
[Richard Levitte]
*) Fix EVP_CIPHER_mode macro.
["Dan S. Camper" <dan@bti.net>]
*) Fix ssl3_read_bytes (ssl/s3_pkt.c): To ignore messages of unknown
type, we must throw them away by setting rr->length to 0.
[D P Chang <dpc@qualys.com>]
Changes between 0.9.6b and 0.9.6c [21 dec 2001]
*) Fix BN_rand_range bug pointed out by Dominikus Scherkl
<Dominikus.Scherkl@biodata.com>. (The previous implementation
worked incorrectly for those cases where range = 10..._2 and
3*range is two bits longer than range.)
[Bodo Moeller]
*) Only add signing time to PKCS7 structures if it is not already
present.
[Steve Henson]
*) Fix crypto/objects/objects.h: "ld-ce" should be "id-ce",
OBJ_ld_ce should be OBJ_id_ce.
Also some ip-pda OIDs in crypto/objects/objects.txt were
incorrect (cf. RFC 3039).
[Matt Cooper, Frederic Giudicelli, Bodo Moeller]
*) Release CRYPTO_LOCK_DYNLOCK when CRYPTO_destroy_dynlockid()
returns early because it has nothing to do.
[Andy Schneider <andy.schneider@bjss.co.uk>]
*) [In 0.9.6c-engine release:]
Fix mutex callback return values in crypto/engine/hw_ncipher.c.
[Andy Schneider <andy.schneider@bjss.co.uk>]
*) [In 0.9.6c-engine release:]
Add support for Cryptographic Appliance's keyserver technology.
(Use engine 'keyclient')
[Cryptographic Appliances and Geoff Thorpe]
*) Add a configuration entry for OS/390 Unix. The C compiler 'c89'
is called via tools/c89.sh because arguments have to be
rearranged (all '-L' options must appear before the first object
modules).
[Richard Shapiro <rshapiro@abinitio.com>]
*) [In 0.9.6c-engine release:]
Add support for Broadcom crypto accelerator cards, backported
from 0.9.7.
[Broadcom, Nalin Dahyabhai <nalin@redhat.com>, Mark Cox]
*) [In 0.9.6c-engine release:]
Add support for SureWare crypto accelerator cards from
Baltimore Technologies. (Use engine 'sureware')
[Baltimore Technologies and Mark Cox]
*) [In 0.9.6c-engine release:]
Add support for crypto accelerator cards from Accelerated
Encryption Processing, www.aep.ie. (Use engine 'aep')
[AEP Inc. and Mark Cox]
*) Add a configuration entry for gcc on UnixWare.
[Gary Benson <gbenson@redhat.com>]
*) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake
messages are stored in a single piece (fixed-length part and
variable-length part combined) and fix various bugs found on the way.
[Bodo Moeller]
*) Disable caching in BIO_gethostbyname(), directly use gethostbyname()
instead. BIO_gethostbyname() does not know what timeouts are
appropriate, so entries would stay in cache even when they have
become invalid.
[Bodo Moeller; problem pointed out by Rich Salz <rsalz@zolera.com>
*) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when
faced with a pathologically small ClientHello fragment that does
not contain client_version: Instead of aborting with an error,
simply choose the highest available protocol version (i.e.,
TLS 1.0 unless it is disabled). In practice, ClientHello
messages are never sent like this, but this change gives us
strictly correct behaviour at least for TLS.
[Bodo Moeller]
*) Fix SSL handshake functions and SSL_clear() such that SSL_clear()
never resets s->method to s->ctx->method when called from within
one of the SSL handshake functions.
[Bodo Moeller; problem pointed out by Niko Baric]
*) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert
(sent using the client's version number) if client_version is
smaller than the protocol version in use. Also change
ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if
the client demanded SSL 3.0 but only TLS 1.0 is enabled; then
the client will at least see that alert.
[Bodo Moeller]
*) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation
correctly.
[Bodo Moeller]
*) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a
client receives HelloRequest while in a handshake.
[Bodo Moeller; bug noticed by Andy Schneider <andy.schneider@bjss.co.uk>]
*) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C
should end in 'break', not 'goto end' which circuments various
cleanups done in state SSL_ST_OK. But session related stuff
must be disabled for SSL_ST_OK in the case that we just sent a
HelloRequest.
Also avoid some overhead by not calling ssl_init_wbio_buffer()
before just sending a HelloRequest.
[Bodo Moeller, Eric Rescorla <ekr@rtfm.com>]
*) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't
reveal whether illegal block cipher padding was found or a MAC
verification error occured. (Neither SSLerr() codes nor alerts
are directly visible to potential attackers, but the information
may leak via logfiles.)
Similar changes are not required for the SSL 2.0 implementation
because the number of padding bytes is sent in clear for SSL 2.0,
and the extra bytes are just ignored. However ssl/s2_pkt.c
failed to verify that the purported number of padding bytes is in
the legal range.
[Bodo Moeller]
*) Add OpenUNIX-8 support including shared libraries
(Boyd Lynn Gerber <gerberb@zenez.com>).
[Lutz Jaenicke]
*) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid
'wristwatch attack' using huge encoding parameters (cf.
James H. Manger's CRYPTO 2001 paper). Note that the
RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use
encoding parameters and hence was not vulnerable.
[Bodo Moeller]
*) BN_sqr() bug fix.
[Ulf M<>ller, reported by Jim Ellis <jim.ellis@cavium.com>]
*) Rabin-Miller test analyses assume uniformly distributed witnesses,
so use BN_pseudo_rand_range() instead of using BN_pseudo_rand()
followed by modular reduction.
[Bodo Moeller; pointed out by Adam Young <AYoung1@NCSUS.JNJ.COM>]
*) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range()
equivalent based on BN_pseudo_rand() instead of BN_rand().
[Bodo Moeller]
*) s3_srvr.c: allow sending of large client certificate lists (> 16 kB).
This function was broken, as the check for a new client hello message
to handle SGC did not allow these large messages.
(Tracked down by "Douglas E. Engert" <deengert@anl.gov>.)
[Lutz Jaenicke]
*) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long]().
[Lutz Jaenicke]
*) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl()
for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>).
[Lutz Jaenicke]
*) Rework the configuration and shared library support for Tru64 Unix.
The configuration part makes use of modern compiler features and
still retains old compiler behavior for those that run older versions
of the OS. The shared library support part includes a variant that
uses the RPATH feature, and is available through the special
configuration target "alpha-cc-rpath", which will never be selected
automatically.
[Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte]
*) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message()
with the same message size as in ssl3_get_certificate_request().
Otherwise, if no ServerKeyExchange message occurs, CertificateRequest
messages might inadvertently be reject as too long.
[Petr Lampa <lampa@fee.vutbr.cz>]
*) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX).
[Andy Polyakov]
*) Modified SSL library such that the verify_callback that has been set
specificly for an SSL object with SSL_set_verify() is actually being
used. Before the change, a verify_callback set with this function was
ignored and the verify_callback() set in the SSL_CTX at the time of
the call was used. New function X509_STORE_CTX_set_verify_cb() introduced
to allow the necessary settings.
[Lutz Jaenicke]
*) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c
explicitly to NULL, as at least on Solaris 8 this seems not always to be
done automatically (in contradiction to the requirements of the C
standard). This made problems when used from OpenSSH.
[Lutz Jaenicke]
*) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
dh->length and always used
BN_rand_range(priv_key, dh->p).
BN_rand_range() is not necessary for Diffie-Hellman, and this
specific range makes Diffie-Hellman unnecessarily inefficient if
dh->length (recommended exponent length) is much smaller than the
length of dh->p. We could use BN_rand_range() if the order of
the subgroup was stored in the DH structure, but we only have
dh->length.
So switch back to
BN_rand(priv_key, l, ...)
where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1
otherwise.
[Bodo Moeller]
*) In
RSA_eay_public_encrypt
RSA_eay_private_decrypt
RSA_eay_private_encrypt (signing)
RSA_eay_public_decrypt (signature verification)
(default implementations for RSA_public_encrypt,
RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt),
always reject numbers >= n.
[Bodo Moeller]
*) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2
to synchronize access to 'locking_thread'. This is necessary on
systems where access to 'locking_thread' (an 'unsigned long'
variable) is not atomic.
[Bodo Moeller]
*) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID
*before* setting the 'crypto_lock_rand' flag. The previous code had
a race condition if 0 is a valid thread ID.
[Travis Vitek <vitek@roguewave.com>]
*) Add support for shared libraries under Irix.
[Albert Chin-A-Young <china@thewrittenword.com>]
*) Add configuration option to build on Linux on both big-endian and
little-endian MIPS.
[Ralf Baechle <ralf@uni-koblenz.de>]
*) Add the possibility to create shared libraries on HP-UX.
[Richard Levitte]
Changes between 0.9.6a and 0.9.6b [9 Jul 2001]
*) Change ssleay_rand_bytes (crypto/rand/md_rand.c)
to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
PRNG state recovery was possible based on the output of
one PRNG request appropriately sized to gain knowledge on
'md' followed by enough consecutive 1-byte PRNG requests
to traverse all of 'state'.
1. When updating 'md_local' (the current thread's copy of 'md')
during PRNG output generation, hash all of the previous
'md_local' value, not just the half used for PRNG output.
2. Make the number of bytes from 'state' included into the hash
independent from the number of PRNG bytes requested.
The first measure alone would be sufficient to avoid
Markku-Juhani's attack. (Actually it had never occurred
to me that the half of 'md_local' used for chaining was the
half from which PRNG output bytes were taken -- I had always
assumed that the secret half would be used.) The second
measure makes sure that additional data from 'state' is never
mixed into 'md_local' in small portions; this heuristically
further strengthens the PRNG.
[Bodo Moeller]
*) Fix crypto/bn/asm/mips3.s.
[Andy Polyakov]
*) When only the key is given to "enc", the IV is undefined. Print out
an error message in this case.
[Lutz Jaenicke]
*) Handle special case when X509_NAME is empty in X509 printing routines.
[Steve Henson]
*) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are
positive and less than q.
[Bodo Moeller]
*) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is
used: it isn't thread safe and the add_lock_callback should handle
that itself.
[Paul Rose <Paul.Rose@bridge.com>]
*) Verify that incoming data obeys the block size in
ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c).
[Bodo Moeller]
*) Fix OAEP check.
[Ulf M<>ller, Bodo M<>ller]
*) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5
RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5
when fixing the server behaviour for backwards-compatible 'client
hello' messages. (Note that the attack is impractical against
SSL 3.0 and TLS 1.0 anyway because length and version checking
means that the probability of guessing a valid ciphertext is
around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98
paper.)
Before 0.9.5, the countermeasure (hide the error by generating a
random 'decryption result') did not work properly because
ERR_clear_error() was missing, meaning that SSL_get_error() would
detect the supposedly ignored error.
Both problems are now fixed.
[Bodo Moeller]
*) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096
(previously it was 1024).
[Bodo Moeller]
*) Fix for compatibility mode trust settings: ignore trust settings
unless some valid trust or reject settings are present.
[Steve Henson]
*) Fix for blowfish EVP: its a variable length cipher.
[Steve Henson]
*) Fix various bugs related to DSA S/MIME verification. Handle missing
parameters in DSA public key structures and return an error in the
DSA routines if parameters are absent.
[Steve Henson]
*) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
in the current directory if neither $RANDFILE nor $HOME was set.
RAND_file_name() in 0.9.6a returned NULL in this case. This has
caused some confusion to Windows users who haven't defined $HOME.
Thus RAND_file_name() is changed again: e_os.h can define a
DEFAULT_HOME, which will be used if $HOME is not set.
For Windows, we use "C:"; on other platforms, we still require
environment variables.
*) Move 'if (!initialized) RAND_poll()' into regions protected by
CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
having multiple threads call RAND_poll() concurrently.
[Bodo Moeller]
*) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a
combination of a flag and a thread ID variable.
Otherwise while one thread is in ssleay_rand_bytes (which sets the
flag), *other* threads can enter ssleay_add_bytes without obeying
the CRYPTO_LOCK_RAND lock (and may even illegally release the lock
that they do not hold after the first thread unsets add_do_not_lock).
[Bodo Moeller]
*) Change bctest again: '-x' expressions are not available in all
versions of 'test'.
[Bodo Moeller]
Changes between 0.9.6 and 0.9.6a [5 Apr 2001]
*) Fix a couple of memory leaks in PKCS7_dataDecode()
[Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
*) Change Configure and Makefiles to provide EXE_EXT, which will contain
the default extension for executables, if any. Also, make the perl
scripts that use symlink() to test if it really exists and use "cp"
if it doesn't. All this made OpenSSL compilable and installable in
CygWin.
[Richard Levitte]
*) Fix for asn1_GetSequence() for indefinite length constructed data.
If SEQUENCE is length is indefinite just set c->slen to the total
amount of data available.
[Steve Henson, reported by shige@FreeBSD.org]
[This change does not apply to 0.9.7.]
*) Change bctest to avoid here-documents inside command substitution
(workaround for FreeBSD /bin/sh bug).
For compatibility with Ultrix, avoid shell functions (introduced
in the bctest version that searches along $PATH).
[Bodo Moeller]
*) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
with des_encrypt() defined on some operating systems, like Solaris
and UnixWare.
[Richard Levitte]
*) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:
On the Importance of Eliminating Errors in Cryptographic
Computations, J. Cryptology 14 (2001) 2, 101-119,
http://theory.stanford.edu/~dabo/papers/faults.ps.gz).
[Ulf Moeller]
*) MIPS assembler BIGNUM division bug fix.
[Andy Polyakov]
*) Disabled incorrect Alpha assembler code.
[Richard Levitte]
*) Fix PKCS#7 decode routines so they correctly update the length
after reading an EOC for the EXPLICIT tag.
[Steve Henson]
[This change does not apply to 0.9.7.]
*) Fix bug in PKCS#12 key generation routines. This was triggered
if a 3DES key was generated with a 0 initial byte. Include
PKCS12_BROKEN_KEYGEN compilation option to retain the old
(but broken) behaviour.
[Steve Henson]
*) Enhance bctest to search for a working bc along $PATH and print
it when found.
[Tim Rice <tim@multitalents.net> via Richard Levitte]
*) Fix memory leaks in err.c: free err_data string if necessary;
don't write to the wrong index in ERR_set_error_data.
[Bodo Moeller]
*) Implement ssl23_peek (analogous to ssl23_read), which previously
did not exist.
[Bodo Moeller]
*) Replace rdtsc with _emit statements for VC++ version 5.
[Jeremy Cooper <jeremy@baymoo.org>]
*) Make it possible to reuse SSLv2 sessions.
[Richard Levitte]
*) In copy_email() check for >= 0 as a return value for
X509_NAME_get_index_by_NID() since 0 is a valid index.
[Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
*) Avoid coredump with unsupported or invalid public keys by checking if
X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
PKCS7_verify() fails with non detached data.
[Steve Henson]
*) Don't use getenv in library functions when run as setuid/setgid.
New function OPENSSL_issetugid().
[Ulf Moeller]
*) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
due to incorrect handling of multi-threading:
1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
3. Count how many times MemCheck_off() has been called so that
nested use can be treated correctly. This also avoids
inband-signalling in the previous code (which relied on the
assumption that thread ID 0 is impossible).
[Bodo Moeller]
*) Add "-rand" option also to s_client and s_server.
[Lutz Jaenicke]
*) Fix CPU detection on Irix 6.x.
[Kurt Hockenbury <khockenb@stevens-tech.edu> and
"Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
*) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
was empty.
[Steve Henson]
[This change does not apply to 0.9.7.]
*) Use the cached encoding of an X509_NAME structure rather than
copying it. This is apparently the reason for the libsafe "errors"
but the code is actually correct.
[Steve Henson]
*) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
Bleichenbacher's DSA attack.
Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
to be set and top=0 forces the highest bit to be set; top=-1 is new
and leaves the highest bit random.
[Ulf Moeller, Bodo Moeller]
*) In the NCONF_...-based implementations for CONF_... queries
(crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
a temporary CONF structure with the data component set to NULL
(which gives segmentation faults in lh_retrieve).
Instead, use NULL for the CONF pointer in CONF_get_string and
CONF_get_number (which may use environment variables) and directly
return NULL from CONF_get_section.
[Bodo Moeller]
*) Fix potential buffer overrun for EBCDIC.
[Ulf Moeller]
*) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
keyUsage if basicConstraints absent for a CA.
[Steve Henson]
*) Make SMIME_write_PKCS7() write mail header values with a format that
is more generally accepted (no spaces before the semicolon), since
some programs can't parse those values properly otherwise. Also make
sure BIO's that break lines after each write do not create invalid
headers.
[Richard Levitte]
*) Make the CRL encoding routines work with empty SEQUENCE OF. The
macros previously used would not encode an empty SEQUENCE OF
and break the signature.
[Steve Henson]
[This change does not apply to 0.9.7.]
*) Zero the premaster secret after deriving the master secret in
DH ciphersuites.
[Steve Henson]
*) Add some EVP_add_digest_alias registrations (as found in
OpenSSL_add_all_digests()) to SSL_library_init()
aka OpenSSL_add_ssl_algorithms(). This provides improved
compatibility with peers using X.509 certificates
with unconventional AlgorithmIdentifier OIDs.
[Bodo Moeller]
*) Fix for Irix with NO_ASM.
["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
*) ./config script fixes.
[Ulf Moeller, Richard Levitte]
*) Fix 'openssl passwd -1'.
[Bodo Moeller]
*) Change PKCS12_key_gen_asc() so it can cope with non null
terminated strings whose length is passed in the passlen
parameter, for example from PEM callbacks. This was done
by adding an extra length parameter to asc2uni().
[Steve Henson, reported by <oddissey@samsung.co.kr>]
*) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
call failed, free the DSA structure.
[Bodo Moeller]
*) Fix to uni2asc() to cope with zero length Unicode strings.
These are present in some PKCS#12 files.
[Steve Henson]
*) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
when writing a 32767 byte record.
[Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
*) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
(RSA objects have a reference count access to which is protected
by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
so they are meant to be shared between threads.)
[Bodo Moeller, Geoff Thorpe; original patch submitted by
"Reddie, Steven" <Steven.Reddie@ca.com>]
*) Fix a deadlock in CRYPTO_mem_leaks().
[Bodo Moeller]
*) Use better test patterns in bntest.
[Ulf M<>ller]
*) rand_win.c fix for Borland C.
[Ulf M<>ller]
*) BN_rshift bugfix for n == 0.
[Bodo Moeller]
*) Add a 'bctest' script that checks for some known 'bc' bugs
so that 'make test' does not abort just because 'bc' is broken.
[Bodo Moeller]
*) Store verify_result within SSL_SESSION also for client side to
avoid potential security hole. (Re-used sessions on the client side
always resulted in verify_result==X509_V_OK, not using the original
result of the server certificate verification.)
[Lutz Jaenicke]
*) Fix ssl3_pending: If the record in s->s3->rrec is not of type
SSL3_RT_APPLICATION_DATA, return 0.
Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
[Bodo Moeller]
*) Fix SSL_peek:
Both ssl2_peek and ssl3_peek, which were totally broken in earlier
releases, have been re-implemented by renaming the previous
implementations of ssl2_read and ssl3_read to ssl2_read_internal
and ssl3_read_internal, respectively, and adding 'peek' parameters
to them. The new ssl[23]_{read,peek} functions are calls to
ssl[23]_read_internal with the 'peek' flag set appropriately.
A 'peek' parameter has also been added to ssl3_read_bytes, which
does the actual work for ssl3_read_internal.
[Bodo Moeller]
*) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
the method-specific "init()" handler. Also clean up ex_data after
calling the method-specific "finish()" handler. Previously, this was
happening the other way round.
[Geoff Thorpe]
*) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
The previous value, 12, was not always sufficient for BN_mod_exp().
[Bodo Moeller]
*) Make sure that shared libraries get the internal name engine with
the full version number and not just 0. This should mark the
shared libraries as not backward compatible. Of course, this should
be changed again when we can guarantee backward binary compatibility.
[Richard Levitte]
*) Fix typo in get_cert_by_subject() in by_dir.c
[Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
*) Rework the system to generate shared libraries:
- Make note of the expected extension for the shared libraries and
if there is a need for symbolic links from for example libcrypto.so.0
to libcrypto.so.0.9.7. There is extended info in Configure for
that.
- Make as few rebuilds of the shared libraries as possible.
- Still avoid linking the OpenSSL programs with the shared libraries.
- When installing, install the shared libraries separately from the
static ones.
[Richard Levitte]
Note read_ahead-flag related fixes.
2000-09-26 11:39:37 +00:00
*) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
and not in SSL_clear because the latter is also used by the
accept/connect functions; previously, the settings made by
SSL_set_read_ahead would be lost during the handshake.
[Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
Document the change.
2000-09-25 11:12:27 +00:00
*) Correct util/mkdef.pl to be selective about disabled algorithms.
Previously, it would create entries for disableed algorithms no
matter what.
[Richard Levitte]
Update the status and version number to 0.9.7-dev.
2000-09-24 17:31:37 +00:00
Harmonize CHANGES and STATUS files between the 0.9.6a branch and the trunk to keep diffs small.
2001-03-22 10:59:41 +00:00
*) Added several new manual pages for SSL_* function.
[Lutz Jaenicke]
Time to build the release. Bump the version info accordingly.
2000-09-24 15:21:30 +00:00
Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
Fix typo in rsautl. Add support for settable verify time in X509_verify_cert(). Document rsautl utility.
2000-09-05 22:30:38 +00:00
Avoid protocol rollback.
2000-09-22 21:39:33 +00:00
*) In ssl23_get_client_hello, generate an error message when faced
with an initial SSL 3.0/TLS record that is too small to contain the
first two bytes of the ClientHello message, i.e. client_version.
(Note that this is a pathologic case that probably has never happened
in real life.) The previous approach was to use the version number
typo
2000-09-22 21:45:49 +00:00
from the record header as a substitute; but our protocol choice
Avoid protocol rollback.
2000-09-22 21:39:33 +00:00
should not depend on that one because it is not authenticated
by the Finished messages.
[Bodo Moeller]
Add some missing info.
2000-09-23 05:17:40 +00:00
*) More robust randomness gathering functions for Windows.
[Jeffrey Altman <jaltman@columbia.edu>]
Only use the new informational verify codes if we specifically ask for them. Fix typo in docs.
2000-09-22 21:32:08 +00:00
*) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
not set then we don't setup the error code for issuer check errors
to avoid possibly overwriting other errors which the callback does
handle. If an application does set the flag then we assume it knows
what it is doing and can handle the new informational codes
appropriately.
[Steve Henson]
Fix ASN1_TYPE bug.
2000-09-21 18:57:00 +00:00
*) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
a general "ANY" type, as such it should be able to decode anything
including tagged types. However it didn't check the class so it would
wrongly interpret tagged types in the same way as their universal
counterpart and unknown types were just rejected. Changed so that the
tagged and unknown types are handled in the same way as a SEQUENCE:
that is the encoding is stored intact. There is also a new type
"V_ASN1_OTHER" which is used when the class is not universal, in this
case we have no idea what the actual type is so we just lump them all
together.
[Steve Henson]
On VMS, stdout may very well lead to a file that is written to in a record-oriented fashion. That means that every write() will write a separate record, which will be read separately by the programs trying to read from it. This can be very confusing. The solution is to put a BIO filter in the way that will buffer text until a linefeed is reached, and then write everything a line at a time, so every record written will be an actual line, not chunks of lines and not (usually doesn't happen, but I've seen it once) several lines in one record. Voila, BIO_f_linebuffer() is born. Since we're so close to release time, I'm making this VMS-only for now, just to make sure no code is needlessly broken by this. After the release, this BIO method will be enabled on all other platforms as well.

Totally remove the supposedly 'faster' variant in BN_mod_mul_montgomery, which calls bn_sqr_recursive without much preparation. bn_sqr_recursive requires the length of its argument to be a power of 2, which is not always the case here. There's no reason for not using BN_sqr -- if a simpler approach to squaring made sense, then why not change BN_sqr? (Using BN_sqr should also speed up DH where g is chosen such that it becomes small [e.g., 2] when converted to Montgomery representation.) Case closed :-)
2000-09-19 23:25:00 +00:00
*) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
Document BN_mod_mul_montgomery bug; make disabled code slightly more correct (this does not solve the problem though).

Work around for Netscape PKCS#7 signedData bug.
2000-09-18 12:30:57 +00:00
*) Disable the check for content being present when verifying detached
signatures in pk7_smime.c. Some versions of Netscape (wrongly)
include zero length content when signing messages.
[Steve Henson]
Rename new BIO_set_shutdown_wr macro to just BIO_shutdown_wr (it's similar to the shutdown(..., SHUT_WR) system call for sockets).
2000-09-17 01:23:53 +00:00
*) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
BIO_ctrl (for BIO pairs).
Add some missing info.

A DSO method for VMS was missing, and I had the code lying around...
2000-09-15 21:22:50 +00:00
*) Add DSO method for VMS.

Add Damien Miller's RPM specification file with a few modifications.
2000-09-14 15:28:44 +00:00
*) Add RPM specification openssl.spec and modify it to build three
packages. The default package contains applications, application
documentation and run-time libraries. The devel package contains
include files, static libraries and function documentation. The
doc package contains the contents of the doc directory. The original
openssl.spec was provided by Damien Miller <djm@mindrot.org>.
[Richard Levitte]
Add a number of documentation files, mostly for SSL routines, but also for a few BIO routines. Submitted by Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>
2000-09-14 13:11:56 +00:00
*) Add a large number of documentation files for many SSL routines.

Not the DSA change.
2000-09-13 01:48:05 +00:00
*) Don't set the two most significant bits to one when generating a
random number < q in the DSA library.
The other log message should have read "Note the DSA change".

New SSL API mode 'SSL_MODE_AUTO_RETRY', which disables the default behaviour that SSL_read may result in SSL_ERROR_WANT_READ.
2000-09-12 20:28:30 +00:00
*) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
the underlying transport is blocking) if a handshake took place.
(The default behaviour is needed by applications such as s_client
and s_server that use select() to determine when to use SSL_read;
but for applications that know in advance when to expect data, it
just makes things more complicated.)
[Bodo Moeller]
Document an old change.
2000-09-11 17:58:09 +00:00
*) Add RAND_egd_bytes(), which gives control over the number of bytes read
from EGD.
[Ben Laurie]
Marin Kraemer <Martin.Kraemer@MchP.Siemens.De> sent us patches to make the OpenSSL commands x50 and req work better on a EBCDIC system.
2000-09-10 14:45:19 +00:00
*) Add a few more EBCDIC conditionals that make `req' and `x509'
work better on such systems.
[Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
Two new PKCS#12 demo programs. Update PKCS12_parse(). Make the keyid in certificate aux info more usable.
2000-09-07 23:14:26 +00:00
*) Add two demo programs for PKCS12_parse() and PKCS12_create().
Update PKCS12_parse() so it copies the friendlyName and the
keyid to the certificates aux info.
[Steve Henson]
Ugh, BIO_find_type() cannot be passed a NULL. Fix doc example, and fix BIO_find_type(). Fix PKCS7_verify(). It was using 'i' for both the loop variable and the verify return value.
2000-09-07 17:42:25 +00:00
*) Fix bug in PKCS7_verify() which caused an infinite loop
if there was more than one signature.
[Sven Uszpelkat <su@celocom.de>]
Major hack of mkdef.pl. There should be no more need to redo the process when some symbols are missing. Instead, all needed info is saved in the .num files, including what conditions are needed for a specific symbol to exist. This was needed for the work I'm doing with shared libraries under VMS.
2000-09-07 08:43:08 +00:00
*) Major change in util/mkdef.pl to include extra information
about each symbol, as well as presentig variables as well
as functions. This change means that there's n more need
to rebuild the .num files when some algorithms are excluded.
[Richard Levitte]
Fix typo in rsautl. Add support for settable verify time in X509_verify_cert(). Document rsautl utility.
2000-09-05 22:30:38 +00:00
*) Allow the verify time to be set by an application,
rather than always using the current time.
[Steve Henson]
*BIG* verify code reorganisation. The old code was painfully primitive and couldn't handle distinct certificates using the same subject name. The new code performs several tests on a candidate issuer certificate based on certificate extensions. It also adds several callbacks to X509_VERIFY_CTX so its behaviour can be customised. Unfortunately some hackery was needed to persuade X509_STORE to tolerate this. This should go away when X509_STORE is replaced, sometime... This must have broken something though :-(
2000-09-05 17:53:58 +00:00
Fix typo in rsautl. Add support for settable verify time in X509_verify_cert(). Document rsautl utility.
2000-09-05 22:30:38 +00:00
*) Phase 2 verify code reorganisation. The certificate
verify code now looks up an issuer certificate by a
number of criteria: subject name, authority key id
and key usage. It also verifies self signed certificates
by the same criteria. The main comparison function is
X509_check_issued() which performs these checks.

The LHASH 'certs' is X509_STORE has now been replaced
by a STACK_OF(X509_OBJECT). This is mainly because an
LHASH can't store or retrieve multiple objects with
the same hash value.
Tagging has now been done, update to the next version (it's not quite as important to keep a low profile here :-))

2000-09-05 22:30:38 +00:00
As a result various functions (which were all internal
use only) have changed to handle the new X509_STORE
structure. This will break anything that messed round
with X509_STORE internally.

2000-09-05 22:30:38 +00:00
The X509_STORE API doesn't directly support the retrieval
of multiple certificates matching a given criteria, however
this can be worked round by performing a lookup first
(which will fill the cache with candidate certificates)
and then examining the cache for matches. This is probably
the best we can do without throwing out X509_LOOKUP
entirely (maybe later...).

All certificate lookup operations now go via a get_issuer()
callback. Although this currently uses an X509_STORE it
can be replaced by custom lookups. This is a simple way
to bypass the X509_STORE hackery necessary to make this
work and makes it possible to use more efficient techniques
in future. A very simple version which uses a simple
STACK for its trusted certificate store is also provided
using X509_STORE_CTX_trusted_stack().

Keep a not of original encoding in certificate requests. Add new option to PKCS7_sign to exclude S/MIME capabilities.
2000-09-05 13:27:57 +00:00
*) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
excludes S/MIME capabilities.
[Steve Henson]
*) When a certificate request is read in keep a copy of the

Various fixes... initialize ex_pathlen to -1 so it isn't checked if pathlen is not present. set ucert to NULL in apps/pkcs12.c otherwise it gets freed twice. remove extraneous '\r' in MIME encoder. Allow a NULL to be passed to X509_gmtime_adj() Make PKCS#7 code use definite length encoding rather then the indefinite stuff it used previously.
2000-08-21 22:02:23 +00:00
*) Modification to PKCS#7 encoding routines to output definite
length encoding. Since currently the whole structures are in
memory there's not real point in using indefinite length
constructed encoding. However if OpenSSL is compiled with

Document the added diversity to the possible log levels.
2000-08-17 23:27:03 +00:00
*) Added more prefixes to parse for in the the strings written
through a logging bio, to cover all the levels that are available
through syslog. The prefixes are now:
PANIC, EMERG, EMR => LOG_EMERG
ALERT, ALR => LOG_ALERT
CRIT, CRI => LOG_CRIT
ERROR, ERR => LOG_ERR
WARNING, WARN, WAR => LOG_WARNING
NOTICE, NOTE, NOT => LOG_NOTICE
INFO, INF => LOG_INFO
DEBUG, DBG => LOG_DEBUG
and as before, if none of those prefixes are present at the
beginning of the string, LOG_ERR is chosen.
On Win32, the LOG_* levels are mapped according to this:
LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
LOG_WARNING => EVENTLOG_WARNING_TYPE
LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE

Fix for bad sorting of object names. Add warning print out if duplicate names found: should end up as a fatal error but a warning for now until they problems are fixed...
2000-08-06 18:43:32 +00:00
*) The obj_dat.pl script was messing up the sorting of object
names. The reason was that it compared the quoted version
of strings as a result "OCSP" > "OCSP Signing" because
" > SPACE. Changed script to store unquoted versions of
names and add quotes on output. It was also omitting some
names from the lookup table if they were given a default
value (that is if SN is missing it is given the same
value as LN and vice versa), these are now added on the
grounds that if an object has a name we should be able to
look it up. Finally added warning output when duplicate
short or long names are found.

Fix SSL 2.0 rollback checking: The previous implementation of the test was never triggered due to an off-by-one error. In s23_clnt.c, don't use special rollback-attack detection padding (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the client; similarly, in s23_srvr.c, don't do the rollback check if SSL 2.0 is the only protocol enabled in the server.

New ASN1_STRING_print_ex() and X509_NAME_print_ex() functions. These are intended to be replacements for the ancient ASN1_STRING_print() and X509_NAME_print() functions. The new functions support RFC2253 and various pretty printing options. It is also possible to display international characters if the terminal properly handles UTF8 encoding (Linux seems to tolerate this if the "unicode_start" script is run). Still needs to be documented, integrated into other utilities and extensively tested.
2000-07-28 01:58:15 +00:00
*) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
these print out strings and name structures based on various
flags including RFC2253 support and proper handling of
multibyte characters. Added options to the 'x509' utility
to allow the various flags to be set.

Make NEG_PUBKEY_BUG on by default. ASN1_TIME fixes. New function c2i_ASN1_OBJECT().
2000-07-26 01:18:37 +00:00
*) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
Also change the functions X509_cmp_current_time() and
X509_gmtime_adj() work with an ASN1_TIME structure,
this will enable certificates using GeneralizedTime in validity
dates to be checked.
[Steve Henson]
*) Make the NEG_PUBKEY_BUG code (which tolerates invalid
negative public key encodings) on by default,
NO_NEG_PUBKEY_BUG can be set to disable it.

*) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
content octets. An i2c_ASN1_OBJECT is unnecessary because
the encoding can be trivially obtained from the structure.

Redo and enhance the support for building shared libraries. Currently there's support for building under Linux and True64 (using examples from the programming manuals), including versioning that is currently the same as OpenSSL versions but should really be a different series. With this change, it's up to the users to decide if they want shared libraries as well as the static ones. This decision now has to be done at configuration time (well, not really, those who know what they do can still do it the same way as before). The OpenSSL programs (openssl and the test programs) are currently always linked statically, but this may change in the future in a configurable manner. The necessary makefile variables to enable this are in place. Also note that I have done absolutely nothing about the Windows target to get something similar. On the other hand, DLLs are already the default there, but without versioning, and I've no idea what the possibilities for such a thing are there...
2000-07-21 15:08:53 +00:00
*) A first attempt at creating official support for shared
libraries through configuration. I've kept it so the
default is static libraries only, and the OpenSSL programs
are always statically linked for now, but there are
preparations for dynamic linking in place.
Apply the Tru64 patch from Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> His comments are: 1) Changes all references for `True64' to be `Tru64', which is the correct spelling for the OS name. 2) Makes `alpha-cc' be the same as `alpha164-cc', and adds an `alphaold-cc' entry that is the same as the previous `alpha-cc'. The reason is that most people these days are using the newer compiler, so it should be the default. 3) Adds a bit of commentary to Configure, regarding the name changes of the OS over the years, so it's not so confusing to people that haven't been with the OS for a while. 4) Adds an `alpha-cc-rpath' target (which is *not* selected automatically by Configure under any circumstance) that builds an RPATH into the shared libraries. This is explained in the comment in Configure. It's very very useful for people that want it, and people that don't want it just shouldn't choose that target. 5) Adds the `-pthread' flag as the best way to get POSIX thread support from the newer compiler. 6) Updates the Makefile targets, so that when the `alpha164-cc', `alpha-cc', or `alpha-cc-rpath' target is what Configure is set to use, it uses a Makefile target that includes the `-msym' option when building the shared library. This is a performance enhancement. 7) Updates `config' so that if it detects you're running version 4 or 5 of the OS, it automatically selects `alpha-cc', but uses `alphaold-cc' for versions 1-3 of the OS. 8) Updates the comment in opensslv.h, fixing both the OS name typo and adding a reference to IRIX 6.x, since the shared library semantics are virtually identical there.
2001-08-10 15:26:21 +00:00
This has been tested on Linux and Tru64.

[Steve Henson]
Fix some typose in the i2d/d2i functions that call the i2c/c2i (they were not using the content length for the headers). Fix ASN1 long form tag encoding. This never worked but it was never tested since it is only used for tags > 30. New options to smime program to allow the PKCS#7 format to be specified and the content supplied externally.
2000-07-10 18:33:05 +00:00
*) New options to smime application. -inform and -outform
allow alternative formats for the S/MIME message including
PEM and DER. The -content option allows the content to be
specified separately. This should allow things like Netscape
form signing output easier to verify.
[Steve Henson]
*) Fix the ASN1 encoding of tags using the 'long form'.
[Steve Henson]
New ASN1 functions that just deal with content octets, not tag+length.
2000-07-07 13:24:36 +00:00
*) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
STRING types. These convert content octets to and from the
underlying type. The actual tag and length octets are
already assumed to have been read in and checked. These
are needed because all other string types have virtually
identical handling apart from the tag. By having versions
of the ASN1 functions that just operate on content octets
IMPLICIT tagging can be handled properly. It also allows
the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
and ASN1_INTEGER are identical apart from the tag.
[Steve Henson]
Document the change.
2000-07-05 02:52:47 +00:00
*) Change the handling of OID objects as follows:
- New object identifiers are inserted in objects.txt, following
the syntax given in objects.README.
- objects.pl is used to process obj_mac.num and create a new
obj_mac.h.
- obj_dat.pl is used to create a new obj_dat.h, using the data in
obj_mac.h.
This is currently kind of a hack, and the perl code in objects.pl
isn't very elegant, but it works as I intended. The simplest way
to check that it worked correctly is to look in obj_dat.h and
check the array nid_objs and make sure the objects haven't moved
around (this is important!). Additions are OK, as well as
consistent name changes.

Change mkstack.pl so it now sorts each group into lexical order. Previously it depended on the order of files in the directory.

It wont however avoid this one :-(

Fixes for Win32 build. This is mostly a work around for the old VC++ problem that it treats func() as func(void). Various prototypes had been added to 'compare' function pointers that triggered this. This could be fixed by removing the prototype, adding function pointer casts to every call or changing the passed function to use the expected arguments. I mostly did the latter. The mkdef.pl script was modified to remove the typesafe functions which no longer exist. Oh and some functions called OPENSSL_freeLibrary() were changed back to FreeLibrary(), wonder how that happened :-)
2000-06-21 02:25:30 +00:00
*) Patches to make OpenSSL compile under Win32 again. Mostly

Safe stack reorganisation in terms of function casts. After some messing around this seems to work but needs a few more tests. Working out the syntax for sk_set_cmp_func() (cast it to a function that itself returns a function pointer) was painful :-( Needs some testing to see what other compilers think of this syntax. Also needs similar stuff for ASN1_SET_OF etc etc.
2000-06-16 23:29:26 +00:00
*) Reorganisation of the stack code. The macros are now all
collected in safestack.h . Each macro is defined in terms of
a "stack macro" of the form SKM_<name>(type, a, b). The
DEBUG_SAFESTACK is now handled in terms of function casts,
this has the advantage of retaining type safety without the
use of additional functions. If DEBUG_SAFESTACK is not defined
then the non typesafe macros are used instead. Also modified the
mkstack.pl script to handle the new form. Needs testing to see
if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK

2000-06-15 23:48:05 +00:00
*) When some versions of IIS use the 'NET' form of private key the
key derivation algorithm is different. Normally MD5(password) is
used as a 128 bit RC4 key. In the modified case
MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
as the old Netscape_RSA functions except they have an additional
'sgckey' parameter which uses the modified algorithm. Also added
an -sgckey command line option to the rsa utility. Thanks to

Slightly faster DSA verification (BN_mod_exp2_mont), marginally faster BN_mod_exp for 1024 bit exponents.

This makes DSA verification about 2 % faster.
[Bodo Moeller]
*) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
(meaning that now 2^5 values will be precomputed, which is only 4 KB
plus overhead for 1024 bit moduli).
This makes exponentiations about 0.5 % faster for 1024 bit

This change will cause builds (by default) to not use different STACK structures and functions for each stack type. The previous behaviour can be enabled by configuring with the "-DDEBUG_SAFESTACK" option. This will also cause "make update" (mkdef.pl in particular) to update the libeay.num and ssleay.num symbol tables with the number of extra functions DEBUG_SAFESTACK creates. The way this change works is to accompany each DECLARE_STACK_OF() macro with a set of "#define"d versions of the sk_##type##_*** functions that ensures all the existing "type-safe" stack calls are precompiled into the underlying stack calls. The presence or abscence of the DEBUG_SAFESTACK symbol controls whether this block of "#define"s or the DECLARE_STACK_OF() macro is taking effect. The block of "#define"s is in turn generated and maintained by a perl script (util/mkstack.pl) that encompasses the block with delimiting C comments. This works in a similar way to the auto-generated error codes and, like the other such maintenance utilities, is invoked by the "make update" target. A long (but mundane) commit will follow this with the results of "make update" - this will include all the "#define" blocks for each DECLARE_STACK_OF() statement, along with stripped down libeay.num and ssleay.num files.
2000-06-01 05:13:52 +00:00
*) The type-safe stack code has been rejigged. It is now only compiled
in when OpenSSL is configured with the DEBUG_SAFESTACK option and
by default all type-specific stack functions are "#define"d back to
standard stack functions. This results in more streamlined output
but retains the type-safety checking possibilities of the original
approach.
[Geoff Thorpe]
The previous commit to crypto/stack/*.[ch] pulled the type-safety strings yet tighter, and also put some heat on the rest of the library by insisting (correctly) that compare callbacks used in stacks are prototyped with "const" parameters. This has led to a depth-first explosion of compiler warnings in the code where 1 constification has led to 3 or 4 more. Fortunately these have all been resolved to completion and the code seems cleaner as a result - in particular many of the _cmp() functions should have been prototyped with "const"s, and now are. There was one little problem however; X509_cmp() should by rights compare "const X509 *" pointers, and it is now declared as such. However, it's internal workings can involve recalculating hash values and extensions if they have not already been setup. Someone with a more intricate understanding of the flow control of X509 might be able to tighten this up, but for now - this seemed the obvious place to stop the "depth-first" constification of the code by using an evil cast (they have migrated all the way here from safestack.h). Fortunately, this is the only place in the code where this was required to complete these type-safety changes, and it's reasonably clear and commented, and seemed the least unacceptable of the options. Trying to take the constification further ends up exploding out considerably, and indeed leads directly into generalised ASN functions which are not likely to cooperate well with this.
2000-06-01 02:36:58 +00:00
*) The STACK code has been cleaned up, and certain type declarations
that didn't make a lot of sense have been brought in line. This has
also involved a cleanup of sorts in safestack.h to more correctly
map type-safe stack functions onto their plain stack counterparts.
This work has also resulted in a variety of "const"ifications of
lots of the code, especially "_cmp" operations which should normally
be prototyped with "const" parameters anyway.

Improve PRNG robustness.
2000-05-30 21:44:36 +00:00
*) When generating bytes for the first time in md_rand.c, 'stir the pool'
by seeding with STATE_SIZE dummy bytes (with zero entropy count).
(The PRNG state consists of two parts, the large pool 'state' and 'md',
where all of 'md' is used each time the PRNG is used, but 'state'
is used only indexed by a cyclic counter. As entropy may not be
well distributed from the beginning, 'md' is important as a
chaining variable. However, the output function chains only half
of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
all of 'md', and seeding with STATE_SIZE dummy bytes will result
in all of 'state' being rewritten, with the new values depending
on virtually all of 'md'. This overcomes the 80 bit limitation.)

2000-05-28 12:44:46 +00:00
By shifting this to the top level EVP_CipherInit() it can be removed from
all individual ciphers. If the cipher wants to handle IVs or keys
differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
flags.
Second phase of EVP cipher overhaul. Change functions like EVP_EncryptUpdate() so they now return a value. These normally have software only implementations which cannot fail so this was acceptable. However ciphers can be implemented in hardware and these could return errors.
2000-05-27 12:38:43 +00:00
Change lots of functions like EVP_EncryptUpdate() to now return a
value: although software versions of the algorithms cannot fail
any installed hardware versions can.
Beginnings of EVP cipher overhaul. This should eventually enhance and tidy up the EVP interface. This patch adds initial support for variable length ciphers and changes S/MIME code to use this. Some other library functions need modifying to support use of modified cipher parameters. Also need to change all the cipher functions that should return error codes, but currenly don't. And of course it needs extensive testing...

Implement SSL_OP_TLS_ROLLBACK_BUG for servers. Call dh_tmp_cb with correct 'is_export' flag. Avoid tabs in CHANGES.
2000-05-25 09:50:40 +00:00
*) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
this option is set, tolerate broken clients that send the negotiated
protocol version number instead of the requested protocol version
number.
[Bodo Moeller]
*) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
i.e. non-zero for export ciphersuites, zero otherwise.
Previous versions had this flag inverted, inconsistent with
rsa_tmp_cb (..._TMP_RSA_CB).

Fix c_rehash script, add -fingerprint option to crl.
2000-05-18 00:33:00 +00:00
*) Enhance c_rehash script. Old version would mishandle certificates
with the same subject name hash and wouldn't handle CRLs at all.
Added -fingerprint option to crl utility, to support new c_rehash
features.

Get rid of more non-ANSI declarations.
2000-05-15 22:54:43 +00:00

Make PKCS#12 code handle missing passwords. Add a couple of FAQs.
2000-05-04 00:08:35 +00:00
*) Make PKCS#12 code work with no password. The PKCS#12 spec
is a little unclear about how a blank password is handled.
Since the password in encoded as a BMPString with terminating
double NULL a zero length password would end up as just the
double NULL. However no password at all is different and is
handled differently in the PKCS#12 key generation code. NS
treats a blank password as zero length. MSIE treats it as no
password on export: but it will try both on import. We now do
the same: PKCS12_parse() tries zero length and no password if
the password is set to "" or NULL (NULL is now a valid password:
it wasn't before) as does the pkcs12 application.

Note apps/x509.c bugfixes.

Avoid leaking memory in thread_hash (and enable memory leak detection for it).
2000-04-29 23:58:05 +00:00
*) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
it in ERR_remove_state if appropriate, and change ERR_get_state
accordingly to avoid race conditions (this is necessary because
thread_hash is no longer constant once set).

[Ulf M<>ller]
Previously, the default RSA_METHOD was NULL until the first RSA structure was initialised, at which point an appropriate default was chosen. This meant a call to RSA_get_default_method might have returned FALSE. This change fixes that; now any called to RSA_new(), RSA_new_method(NULL), or RSA_get_default_method() will ensure that a default is chosen if it wasn't already.
2000-04-20 06:44:18 +00:00
*) RSA_get_default_method() will now cause a default
RSA_METHOD to be chosen if one doesn't exist already.
Previously this was only set during a call to RSA_new()
or RSA_new_method(NULL) meaning it was possible for
RSA_get_default_method() to return NULL.
[Geoff Thorpe]
This change facilitates name translation for shared libraries. The technique used is far from perfect and alternatives are welcome. Basically if the translation flag is set, the string is not too long, and there appears to be no path information in the string, then it is converted to whatever the standard should be for the DSO_METHOD in question, eg; blah --> libblah.so on *nix, and blah --> blah.dll on win32. This change also introduces the DSO_ctrl() function that is used by the name translation stuff.
2000-04-19 21:45:17 +00:00
*) Added native name translation to the existing DSO code
that will convert (if the flag to do so is set) filenames
that are sufficiently small and have no path information
into a canonical native form. Eg. "blah" converted to
"libblah.so" or "blah.dll" etc.

including the 0 terminator. For ERR_error_string_n, 'buf'
may not be NULL.

new functions (NCONF_*, for "New CONF") to handle it. The now
old CONF_* functions are still there, but are reimplemented to
work in terms of the new functions. Also, a set of functions
to handle the internal storage of the configuration data is
provided to make it easier to write new configuration file
reader "classes" (I can definitely see something reading a
configuration file in XML format, for example), called _CONF_*,
or "the configuration storage API"...
The new configuration file reading functions are:

NCONF_default and NCONF_WIN32 are method (or "class") choosers,
NCONF_new creates a new CONF object. This works in the same way
as other interfaces in OpenSSL, like the BIO interface.
NCONF_dump_* dump the internal storage of the configuration file,
which is useful for debugging. All other functions take the same
arguments as the old CONF_* functions wth the exception of the
first that must be a `CONF *' instead of a `LHASH *'.
To make it easer to use the new classes with the old CONF_* functions,
the function CONF_set_default_method is provided.

2000-03-30 08:12:35 +00:00
*) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status

Fix typo in -clrext option, but add a compatibility hack because 0.9.5a should not break anything that works in 0.9.5.
2000-03-27 18:10:08 +00:00

Copy DH key (if available) in addition to the bare parameters in SSL_new. If SSL_OP_SINGLE_DH_USE is set, don't waste time in SSL_[CTX_]set_tmp_dh on computing a DH key that will be ignored anyway. ssltest -dhe1024dsa (w/ 160-bit sub-prime) had an unfair performance advantage over -dhe1024 (safe prime): SSL_OP_SINGLE_DH_USE was effectively always enabled because SSL_new ignored the DH key set in the SSL_CTX. Now -dhe1024 takes the server only about twice as long as -dhe1024dsa instead of three times as long (for 1024 bit RSA with 1024 bit DH).
2000-03-13 17:07:04 +00:00
*) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
is set; it will be thrown away anyway because each handshake creates
its own key.
ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
to parameters -- in previous versions (since OpenSSL 0.9.3) the
'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
[Bodo Moeller]
Mention -ign_eof.
2000-03-10 13:49:02 +00:00
*) New s_client option -ign_eof: EOF at stdin is ignored, and
'Q' and 'R' lose their special meanings (quit/renegotiate).
This is part of what -quiet does; unlike -quiet, -ign_eof
does not suppress any output.

X509_TRUST_COMPAT is the old trust behaviour: only and
automatically trust self signed roots in certificate store. A
new trust setting X509_TRUST_DEFAULT is used to specify that
a purpose has no associated trust setting and it should instead
use the value in the default purpose.

Fix the PKCS#8 DSA code so it works again. All the broken formats worked but the valid didn't :-(
2000-03-07 01:03:33 +00:00

Preserve reason strings in automatically build tables.
2000-03-05 00:19:36 +00:00
*) In util/mkerr.pl (which implements 'make errors'), preserve
reason strings from the previous version of the .c file, as
the default to have only downcase letters (and digits) in
automatically generated reasons codes is not always appropriate.
[Bodo Moeller]
Generate correct error reasons strings for SYSerr.
2000-03-04 01:36:53 +00:00
*) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
using strerror. Previously, ERR_reason_error_string() returned
library names as reason strings for SYSerr; but SYSerr is a special
case where small numbers are errno values, not library numbers.
[Bodo Moeller]
New '-dsaparam' option for 'openssl dhparam', and related fixes.
2000-03-03 22:18:19 +00:00
*) Add '-dsaparam' option to 'openssl dhparam' application. This
converts DSA parameters into DH parameters. (When creating parameters,
DSA_generate_parameters is used.)
[Bodo Moeller]
*) Include 'length' (recommended exponent length) in C code generated
by 'openssl dhparam -C'.
[Bodo Moeller]
Move the 'file scope' argument in set_label to the third argument: the second was being used already.
2000-03-03 00:06:40 +00:00
*) The second argument to set_label in perlasm was already being used
so couldn't be used as a "file scope" flag. Moved to third argument
which was free.
[Steve Henson]
Use RAND_pseudo_bytes, not RAND_bytes, for IVs/salts.
2000-03-02 22:44:55 +00:00
*) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
instead of RAND_bytes for encryption IVs and salts.
[Bodo Moeller]
Use RAND_METHOD for implementing RAND_status.
2000-03-02 14:34:58 +00:00
*) Include RAND_status() into RAND_METHOD instead of implementing
it only for md_rand.c Otherwise replacing the PRNG by calling
RAND_set_rand_method would be impossible.
[Bodo Moeller]
Note bug fix for the DSA infinite loop
2000-03-01 19:07:58 +00:00

2000-01-27 19:31:26 +00:00
Ouch! PKCS7_encrypt() was heading MIME text headers twice because it added them manually and as part of SMIME_crlf_copy(). Removed the manual add.

Make ASN1 types real typedefs. Rebuild error files.
2000-02-26 19:25:31 +00:00
*) Change the ASN1 types so they are typedefs by default. Before
almost all types were #define'd to ASN1_STRING which was causing
STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
for example.
[Steve Henson]
More get0 et al. changes. Also provide fgrep targets in CHANGES where the new functions are mentioned.
2000-02-26 08:36:46 +00:00
*) Change names of new functions to the new get1/get0 naming
convention: After 'get1', the caller owns a reference count
and has to call ..._free; 'get0' returns a pointer to some
data structure without incrementing reference counters.
(Some of the existing 'get' functions increment a reference
counter, some don't.)
Similarly, 'set1' and 'add1' functions increase reference
counters or duplicate objects.
Rename functions for new convention.

Allow code which calls RSA temp key callback to cope with a failure. Fix typos in some error codes.
2000-02-25 00:23:48 +00:00

RAND_egd() and RAND_status(). In the command line application,
the EGD socket can be specified like a seed file using RANDFILE

Allow ADH to be used but not present in the default cipher list. Allow CERTIFICATE to be used in PEM headers for PKCS#7 structures: some CAs do this.
2000-02-23 01:11:01 +00:00
*) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
Some CAs (e.g. Verisign) distribute certificates in this form.
[Steve Henson]
*) Remove the SSL_ALLOW_ADH compile option and set the default cipher
list to exclude them. This means that no special compilation option
is needed to use anonymous DH: it just needs to be included in the
cipher list.

Change EVP_MD_CTX_type so it is more logical and add EVP_MD_CTX_md for the old functionality. Various warning fixes. Initial EVP symmetric cipher docs.
2000-02-22 02:59:26 +00:00
*) Change the EVP_MD_CTX_type macro so its meaning consistent with
EVP_MD_type. The old functionality is available in a new macro called
EVP_MD_md(). Change code that uses it and update docs.
[Steve Henson]
Move MAC computations for Finished from ssl3_read_bytes into ssl3_get_message, which is more logical (and avoids a bug, in addition to the one that I introduced yesterday :-) and makes Microsoft "fast SGC" less special. MS SGC should still work now without an extra state of its own (it goes directly to SSL3_ST_SR_CLNT_HELLO_C, which is the usual state for reading the body of a Client Hello message), however this should be tested to make sure, and I don't have a MS SGC client.
2000-02-21 10:16:30 +00:00
*) ..._ctrl functions now have corresponding ..._callback_ctrl functions
where the 'void *' argument is replaced by a function pointer argument.
Previously 'void *' was abused to point to functions, which works on
many platforms, but is not correct. As these functions are usually
called by macros defined in OpenSSL header files, most source code
should work without changes.

[Richard Levitte, Ulf and Bodo M<>ller]
Move MAC computations for Finished from ssl3_read_bytes into ssl3_get_message, which is more logical (and avoids a bug, in addition to the one that I introduced yesterday :-) and makes Microsoft "fast SGC" less special. MS SGC should still work now without an extra state of its own (it goes directly to SSL3_ST_SR_CLNT_HELLO_C, which is the usual state for reading the body of a Client Hello message), however this should be tested to make sure, and I don't have a MS SGC client.

record layer.
[Bodo Moeller]
Change the 'other' structure in certificate aux info.
2000-02-20 18:27:23 +00:00
*) Change the 'other' type in certificate aux info to a STACK_OF
X509_ALGOR. Although not an AlgorithmIdentifier as such it has
the required ASN1 format: arbitrary types determined by an OID.
[Steve Henson]
New functions and option to use NEW in certificate requests.
2000-02-18 00:54:21 +00:00
*) Add some PEM_write_X509_REQ_NEW() functions and a command line
argument to 'req'. This is not because the function is newer or
better than others it just uses the work 'NEW' in the certificate
request header lines. Some software needs this.
[Steve Henson]
Pass phrase reorganisation.
2000-02-16 23:16:01 +00:00
*) Reorganise password command line arguments: now passwords can be
obtained from various sources. Delete the PEM_cb function and make
it the default behaviour: i.e. if the callback is NULL and the
usrdata argument is not NULL interpret it as a null terminated pass
phrase. If usrdata and the callback are NULL then the pass phrase
is prompted for as usual.
[Steve Henson]
Add support for Compaq Atalla crypto accelerator.
2000-02-16 22:15:39 +00:00
*) Add support for the Compaq Atalla crypto accelerator. If it is installed,
the support is automatically enabled. The resulting binaries will
autodetect the card and use it if present.
[Ben Laurie and Compaq Inc.]
Fix for Netscape "hang" bug.
2000-02-15 14:19:44 +00:00
*) Work around for Netscape hang bug. This sends certificate request
and server done in one record. Since this is perfectly legal in the
SSL/TLS protocol it isn't a "bug" option and is on by default. See
the bugs/SSLv3 entry for more info.

[Steve Henson]
Improve bntest slightly, and fix another bug in the BN library.
2000-02-06 15:56:59 +00:00
*) Bug fix for BN_div_recp() for numerators with an even number of
bits.
[Ulf M<>ller]
*) More tests in bntest.c, and changed test_bn output.
[Ulf M<>ller]
Support for MacOS X (Rhapsody) is added. Also get rid of volatile qualifier in asm definitions as it prevents compiler from moving the instruction(s) during optimization pass.
2000-02-06 11:15:20 +00:00
*) ./config recognizes MacOS X now.
[Andy Polyakov]
BN_div bugfix. The q-- loop should not be entered in the n0==d0 case.
2000-02-06 00:25:39 +00:00
*) Bug fix for BN_div() when the first words of num and divsor are
equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
[Ulf M<>ller]
Add support for some broken PKCS#8 formats.
2000-02-05 21:07:56 +00:00
*) Add support for various broken PKCS#8 formats, and command line
options to produce them.
[Steve Henson]
New functions BN_CTX_start(), BN_CTX_get(), BN_CTX_end() to access temporary BIGNUMs. BN_CTX still uses a fixed number of BIGNUMs, but the BN_CTX implementation could now easily be changed.
2000-02-05 14:17:32 +00:00
*) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
get temporary BIGNUMs from a BN_CTX.
[Ulf M<>ller]
*) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
for p == 0.
[Ulf M<>ller]
Rename SSLeay_add_all_algorithms() et al to OpenSSL_add_all_algorithms(). Move these into separate files so they work properly.
2000-02-04 14:01:38 +00:00
*) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
include a #define from the old name to the new. The original intent
was that statically linked binaries could for example just call
SSLeay_add_all_ciphers() to just add ciphers to the table and not
link with digests. This never worked becayse SSLeay_add_all_digests()
and SSLeay_add_all_ciphers() were in the same source file so calling
one would link with the other. They are now in separate source files.
[Steve Henson]
Add new -notext option to 'ca', -pubkey option to spkac. Remove some "WTF??" casts from applications. Fixes to keep VC++ happy and avoid warnings. Docs tidy.
2000-02-03 02:56:48 +00:00
*) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
[Steve Henson]
rndsort{Miller, Rabin} primality test.
2000-02-02 21:20:44 +00:00
*) Use a less unusual form of the Miller-Rabin primality test (it used
a binary algorithm for exponentiation integrated into the Miller-Rabin
loop, our standard modexp algorithms are faster).
[Bodo Moeller]

[Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
Note changes.
2000-01-30 23:34:33 +00:00
*) Source code cleanups: use const where appropriate, eliminate casts,
use void * instead of char * in lhash.
[Ulf M<>ller]
Make DSA_generate_parameters, and fix a couple of bug (including another problem in the s3_srvr.c state machine).
2000-01-30 02:23:03 +00:00
*) Bugfix: ssl3_send_server_key_exchange was not restartable
(the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
this the server could overwrite ephemeral keys that the client
has already seen).
[Bodo Moeller]
*) Turn DSA_is_prime into a macro that calls BN_is_prime,
using 50 iterations of the Rabin-Miller test.
DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
iterations of the Rabin-Miller test as required by the appendix
to FIPS PUB 186[-1]) instead of DSA_is_prime.
As BN_is_prime_fasttest includes trial division, DSA parameter
generation becomes much faster.
This implies a change for the callback functions in DSA_is_prime
Documentation for BN_is_prime_fasttest.
2000-01-30 11:05:39 +00:00
and DSA_generate_parameters: The callback function is called once
for each positive witness in the Rabin-Miller test, not just
occasionally in the inner loop; and the parameters to the
callback function now provide an iteration count for the outer
loop rather than for the current invocation of the inner loop.
DSA_generate_parameters additionally can call the callback
function with an 'iteration count' of -1, meaning that a
candidate has passed the trial division test (when q is generated
from an application-provided seed, trial division is skipped).
Make DSA_generate_parameters, and fix a couple of bug (including another problem in the s3_srvr.c state machine).

Tiny changes to previous patch (the log message was meant to be "Make DSA_generate_parameters faster").

an additional BN_CTX * argument (whereas BN_is_prime always
has to allocate at least one BN_CTX).

Fix CRL encoding bug.
2000-01-29 00:00:26 +00:00
*) Fix for bug in CRL encoding. The validity dates weren't being handled
as ASN1_TIME.
[Steve Henson]
New -pkcs12 option to CA.pl. Document CA.pl script. Initialise and free up the extra DH fields (nothing uses them yet though).
2000-01-28 01:35:31 +00:00
*) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
[Steve Henson]
Document DSA and SHA. New function BN_pseudo_rand(). Use BN_prime_checks_size(BN_num_bits(w)) rounds of Miller-Rabin when generating DSA primes (why not use BN_is_prime()?)
2000-01-27 19:31:26 +00:00
*) New function BN_pseudo_rand().
[Ulf M<>ller]
Bump after tarball rolling. Friends, feel free to start again hacking for 0.9.5... ;)

Run ispell. Clean up bn_mont.c.
2000-01-27 01:50:42 +00:00
*) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
bignum version of BN_from_montgomery() with the working code from
SSLeay 0.9.0 (the word based version is faster anyway), and clean up
the comments.
[Ulf M<>ller]
Avoid a race condition.
2000-01-24 17:57:56 +00:00
*) Avoid a race condition in s2_clnt.c (function get_server_hello) that
made it impossible to use the same SSL_SESSION data structure in
SSL2 clients in multiple threads.
[Bodo Moeller]
Improve clarity.
2000-01-24 16:02:29 +00:00
*) The return value of RAND_load_file() no longer counts bytes obtained
by stat(). RAND_load_file(..., -1) is new and uses the complete file
to seed the PRNG (previously an explicit byte count was required).
[Ulf M<>ller, Bodo M<>ller]
Document RAND_load_file change.
2000-01-24 14:42:26 +00:00
Tidy up CRYPTO_EX_DATA structures.
2000-01-23 23:41:49 +00:00
*) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
used (char *) instead of (void *) and had casts all over the place.
[Steve Henson]
Document the DH library, and make some minor changes along the way.
2000-01-22 20:05:23 +00:00
*) Make BN_generate_prime() return NULL on error if ret!=NULL.
[Ulf M<>ller]
Make DSA_generate_parameters, and fix a couple of bug (including another problem in the s3_srvr.c state machine).
2000-01-30 02:23:03 +00:00
*) Retain source code compatibility for BN_prime_checks macro:
BN_is_prime(..., BN_prime_checks, ...) now uses
BN_prime_checks_for_size to determine the appropriate number of
Rabin-Miller iterations.
Document the DH library, and make some minor changes along the way.
2000-01-22 20:05:23 +00:00
[Ulf M<>ller]
*) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
DH_CHECK_P_NOT_SAFE_PRIME.
(Check if this is true? OpenPGP calls them "strong".)
[Ulf M<>ller]
Add new program dhparam and update docs.
2000-01-22 13:58:29 +00:00
*) Merge the functionality of "dh" and "gendh" programs into a new program
"dhparam". The old programs are retained for now but will handle DH keys
(instead of parameters) in future.
[Steve Henson]
Make s_server, s_client check cipher list return codes. Update docs.
2000-01-23 02:28:08 +00:00
*) Make the ciphers, s_server and s_client programs check the return values
when a new cipher list is set.
[Steve Henson]
*) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
ciphers. Before when the 56bit ciphers were enabled the sorting was
wrong.
The syntax for the cipher sorting has been extended to support sorting by
cipher-strength (using the strength_bits hard coded in the tables).
The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
Fix a bug in the cipher-command parser: when supplying a cipher command
string with an "undefined" symbol (neither command nor alphanumeric
[A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
an error is flagged.
Due to the strength-sorting extension, the code of the
ssl_create_cipher_list() function was completely rearranged. I hope that
the readability was also increased :-)
[Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
Add new program dhparam and update docs.
2000-01-22 13:58:29 +00:00
Make -CAcreateserial start from 1 instead of 0 for serial numbers.
2000-01-21 02:42:14 +00:00
*) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
for the first serial number and places 2 in the serial number file. This
avoids problems when the root CA is created with serial number zero and
the first user certificate has the same issuer name and serial number
as the root CA.
[Steve Henson]
Finish off the X509_ATTRIBUTE string stuff.
2000-01-20 01:37:17 +00:00
*) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
the new code. Add documentation for this stuff.
[Steve Henson]
Rename X509_att*() stuff to X509at_*(), add X509_REQ wrappers.
2000-01-19 01:02:13 +00:00
*) Changes to X509_ATTRIBUTE utilities. These have been renamed from
X509_*() to X509at_*() on the grounds that they don't handle X509
structures and behave in an analagous way to the X509v3 functions:
they shouldn't be called directly but wrapper functions should be used
instead.
So we also now have some wrapper functions that call the X509at functions
when passed certificate requests. (TO DO: similar things can be done with
PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
things. Some of these need some d2i or i2d and print functionality
Finish off the X509_ATTRIBUTE string stuff.
2000-01-20 01:37:17 +00:00
because they handle more complex structures.)

More X509_ATTRIBUTE changes.
2000-01-07 00:55:54 +00:00
*) Add PKCS#10 attributes to field table: challengePassword,
unstructuredName and unstructuredAddress. These are taken from
draft PKCS#9 v2.0 but are compatible with v1.2 provided no
international characters are used.
More changes to X509_ATTRIBUTE code: allow the setting of types
based on strings. Remove the 'loc' parameter when adding
attributes because these will be a SET OF encoding which is sorted
in ASN1 order.
[Steve Henson]
Initial automation changes to 'req' and X509_ATTRIBUTE functions.
2000-01-06 01:26:48 +00:00
*) Initial changes to the 'req' utility to allow request generation
automation. This will allow an application to just generate a template
file containing all the field values and have req construct the
request.
Initial support for X509_ATTRIBUTE handling. Stacks of these are
used all over the place including certificate requests and PKCS#7
structures. They are currently handled manually where necessary with
some primitive wrappers for PKCS#7. The new functions behave in a

more complex types. The string types like challengePassword can

be handled by the string table functions.
Initial automation changes to 'req' and X509_ATTRIBUTE functions.
2000-01-06 01:26:48 +00:00
Also modified the multi byte string table handling. Now there is
a 'global mask' which masks out certain types. The table itself
can use the flag STABLE_NO_MASK to ignore the mask setting: this
is useful when for example there is only one permissible type
(as in countryName) and using the mask might result in no valid
types at all.
[Steve Henson]
New functions SSL_get_finished, SSL_get_peer_finished. Add short state string for MS SGC.
2000-01-06 01:19:17 +00:00
*) Clean up 'Finished' handling, and add functions SSL_get_finished and
SSL_get_peer_finished to allow applications to obtain the latest
Finished messages sent to the peer or expected from the peer,
respectively. (SSL_get_peer_finished is usually the Finished message
actually received from the peer, otherwise the protocol will be aborted.)
As the Finished message are message digests of the complete handshake
(with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
be used for external authentication procedures when the authentication
provided by SSL/TLS is not desired or is not enough.
Use separate arrays for certificate verify and for finished hashes.

Add support for MS "fast SGC".
2000-01-02 18:52:58 +00:00
*) Add support for MS "fast SGC". This is arguably a violation of the
SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
weak crypto and after checking the certificate is SGC a second one
with strong crypto. MS SGC stops the first handshake after receiving
the server certificate message and sends a second client hello. Since
a server will typically do all the time consuming operations before
expecting any further messages from the client (server key exchange
is the most expensive) there is little difference between the two.
To get OpenSSL to support MS SGC we have to permit a second client
hello message after we have sent server done. In addition we have to
Move MAC computations for Finished from ssl3_read_bytes into ssl3_get_message, which is more logical (and avoids a bug, in addition to the one that I introduced yesterday :-) and makes Microsoft "fast SGC" less special. MS SGC should still work now without an extra state of its own (it goes directly to SSL3_ST_SR_CLNT_HELLO_C, which is the usual state for reading the body of a Client Hello message), however this should be tested to make sure, and I don't have a MS SGC client.

Fix some of the command line password stuff. New function that can automatically determine the type of a DER encoded "traditional" format private key and change some of the d2i functions to use it instead of requiring the application to work out the key type.
2000-01-01 16:42:49 +00:00
*) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
if a DER encoded private key is RSA or DSA traditional format. Changed
d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
format DER encoded private key. Newer code should use PKCS#8 format which
has the key type encoded in the ASN1 structure. Added DER private key
support to pkcs8 application.

Don't request client certificate in anonymous ciphersuites except when following the specs is bound to fail.
1999-12-29 17:43:03 +00:00
*) SSL 3/TLS 1 servers now don't request certificates when an anonymous
ciphersuites has been selected (as required by the SSL 3/TLS 1
specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
is set, we interpret this as a request to violate the specification
(the worst that can happen is a handshake failure, and 'correct'
behaviour would result in a handshake failure anyway).

Fix SSL_CTX_add_session: When two SSL_SESSIONs have the same ID, they can sometimes be different memory structures.
1999-12-29 14:29:32 +00:00
*) In SSL_CTX_add_session, take into account that there might be multiple
SSL_SESSION structures with the same session ID (e.g. when two threads
concurrently obtain them from an external cache).
The internal cache can handle only one SSL_SESSION with a given ID,
so if there's a conflict, we now throw out the old one to achieve
consistency.

Add OIDs for idea and blowfish. Unfortunately these are in the middle of the OID table so the diff is rather large :-(
1999-12-29 02:59:18 +00:00
*) Add OIDs for idea and blowfish in CBC mode. This will allow both
to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
some routines that use cipher OIDs: some ciphers do not have OIDs
defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
example.

Simplify the trust structure: basically zap the bit strings and represent everything by OIDs.

typically have values the same as the extended key usage extension
and any application specific purposes.
The trust checking code now has a default behaviour: it will just
check for an object with the same NID as the passed id. Functions can
be provided to override either the default behaviour or the behaviour
for a given id. SSL client, server and email already have functions

Rebuild of the OpenSSL memory allocation and deallocation routines.

OpenSSL already comes with functionality to find memory leaks, but
this gives people a chance to debug other memory problems.
- Made sure some changed behavior is documented in CHANGES. - Moved the handling of compile-time defaults from crypto.h to mem_dbg.c, since it doesn't make sense for the library users to try to affect this without recompiling libcrypto. - Made sure V_CRYPTO_MDEBUG_TIME and V_CRYPTO_MDEBUG_THREAD had clear and constant definitions. - Aesthetic correction.

functionality to handle multipart/signed properly) and a utility
called 'smime' to call all this stuff. This is based on code I
originally wrote for Celo who have kindly allowed it to be
included in OpenSSL.

Add functions des_set_key_checked, des_set_key_unchecked. Never use des_set_key (it depends on the global variable des_check_key), but usually des_set_key_unchecked. Only destest.c bothered to look at the return values of des_set_key, but it did not set des_check_key -- if it had done so, most checks would have failed because of wrong parity and because of weak keys.
1999-12-03 20:24:21 +00:00
*) Add variants des_set_key_checked and des_set_key_unchecked of
des_set_key (aka des_key_sched). Global variable des_check_key
decides which of these is called by des_set_key; this way
des_check_key behaves as it always did, but applications and
the library itself, which was buggy for des_check_key == 1,
have a cleaner way to pick the version they need.

Change the trust and purpose code so it doesn't need init either and has a static and dynamic mix.

dynamic mix. In both cases the ids can be used as an index into the
table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
functions so they accept a list of the field values and the
application doesn't need to directly manipulate the X509_TRUST
structure.
[Steve Henson]
*) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
need initialising.
[Steve Henson]
Modify the X509 V3 extension lookup code.
1999-12-01 01:49:46 +00:00
*) Modify the way the V3 extension code looks up extensions. This now
works in a similar way to the object code: we have some "standard"
extensions in a static table which is searched with OBJ_bsearch()
and the application can add dynamic ones if needed. The file
crypto/x509v3/ext_dat.h now has the info: this file needs to be
updated whenever a new extension is added to the core code and kept
in ext_nid order. There is a simple program 'tabtest.c' which checks
this. New extensions are not added too often so this file can readily
be maintained manually.
There are two big advantages in doing things this way. The extensions
can be looked up immediately and no longer need to be "added" using
X509V3_add_standard_extensions(): this function now does nothing.
[Side note: I get *lots* of email saying the extension code doesn't
work because people forget to call this function]
Also no dynamic allocation is done unless new extensions are added:
so if we don't add custom extensions there is no need to call
X509V3_EXT_cleanup().
[Steve Henson]
Make salting the default. Fail gracefully if the input is not salted.
1999-11-30 20:15:19 +00:00
*) Modify enc utility's salting as follows: make salting the default. Add a
magic header, so unsalted files fail gracefully instead of just decrypting
to garbage. This is because not salting is a big security hole, so people
should be discouraged from doing it.
[Ben Laurie]
Initial trust code: allow setting of trust checking functions in a table. Doesn't do too much yet. Make the -<digestname> options in 'x509' affect all relevant options. Change the name of the 'notrust' options to 'reject' as this causes less confusion and is a better description of the effect. A few constification changes.
1999-11-27 01:14:04 +00:00
*) Fixes and enhancements to the 'x509' utility. It allowed a message
digest to be passed on the command line but it only used this
parameter when signing a certificate. Modified so all relevant
operations are affected by the digest parameter including the
-fingerprint and -x509toreq options. Also -x509toreq choked if a
DSA key was used because it didn't fix the digest.
[Steve Henson]
Add trust setting support to the verify code. It now checks the trust settings of the root CA. After a few fixes it seems to work OK. Still need to add support to SSL and S/MIME code though.
1999-11-27 19:43:10 +00:00
*) Initial certificate chain verify code. Currently tests the untrusted
certificates for consistency with the verify purpose (which is set
when the X509_STORE_CTX structure is set up) and checks the pathlength.
There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
Remainder of SSL purpose and trust code: trust and purpose setting in SSL_CTX and SSL, functions to set them and defaults if no values set.
1999-11-29 22:35:00 +00:00
this is because it will reject chains with invalid extensions whereas
every previous version of OpenSSL and SSLeay made no checks at all.
Add trust setting support to the verify code. It now checks the trust settings of the root CA. After a few fixes it seems to work OK. Still need to add support to SSL and S/MIME code though.
1999-11-27 19:43:10 +00:00
Trust code: checks the root CA for the relevant trust settings. Trust
settings have an initial value consistent with the verify purpose: e.g.
if the verify purpose is for SSL client use it expects the CA to be
trusted for SSL client use. However the default value can be changed to
permit custom trust settings: one example of this would be to only trust
certificates from a specific "secure" set of CAs.
Initial chain verify code: not tested probably not working at present. However nothing enables it yet so this doesn't matter :-)
1999-11-24 01:31:49 +00:00
Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
which should be used for version portability: especially since the
verify structure is likely to change more often now.
New options to the -verify program which can be used for chain verification. Extend the X509_PURPOSE structure to include shortnames for purposed and default trust ids. Still need some extendable trust checking code and integration with the SSL and S/MIME code.

Two new options to the verify program: -untrusted allows a set of
untrusted certificates to be passed in and -purpose which sets the
intended purpose of the certificate. If a purpose is set then the
new chain verify code is used to check extension consistency.

never in a public release so they have been deleted. Changed dsa/rsa
utilities to handle the new format: note no releases ever handled public
keys so we should be OK.
The primary motivation for this change is to avoid the same fiasco
that dogs private keys: there are several incompatible private key
formats some of which are standard and some OpenSSL specific and
require various evil hacks to allow partial transparent handling and
even then it doesn't work with DER formats. Given the option anything
other than PKCS#8 should be dumped: but the other formats have to

With public keys and the benefit of hindsight one standard format
is used which works with EVP_PKEY, RSA or DSA structures: though
it clearly returns an error if you try to read the wrong kind of key.

*) Fixes to crypto/x509/by_file.c the code to read in certificates and
CRLs would fail if the file contained no certificates or no CRLs:
added a new function to read in both types and return the number
read: this means that if none are read it will be an error. The
DER versions of the certificate and CRL reader would always fail
because it isn't possible to mix certificates and CRLs in DER format
without choking one or the other routine. Changed this to just read
a certificate: this is the best we can do. Also modified the code
in apps/verify.c to take notice of return codes: it was previously
attempting to read in certificates from NULL pointers and ignoring
any errors: this is one reason why the cert and CRL reader seemed
to work. It doesn't check return codes from the default certificate
routines: these may well fail if the certificates aren't installed.

*) First update to verify code. Change the verify utility
so it warns if it is passed a self signed certificate:
for consistency with the normal behaviour. X509_verify
has been modified to it will now verify a self signed
certificate if *exactly* the same certificate appears
in the store: it was previously impossible to trust a
single self signed certificate. This means that:
openssl verify ss.pem
now gives a warning about a self signed certificate but
openssl verify -CAfile ss.pem ss.pem
is OK.

Store verify_result with sessions to avoid potential security hole.
1999-11-16 23:15:41 +00:00
*) For servers, store verify_result in SSL_SESSION data structure
(and add it to external session representation).
This is needed when client certificate verifications fails,
but an application-provided verification callback (set by
SSL_CTX_set_cert_verify_callback) allows accepting the session
anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
but returns 1): When the session is reused, we have to set
ssl->verify_result to the appropriate error code to avoid
security holes.

New function X509_cmp().
1999-11-16 00:56:03 +00:00
*) New function X509_cmp(). Oddly enough there wasn't a function
to compare two certificates. We do this by working out the SHA1
hash and comparing that. X509_cmp() will be needed by the trust
code.

*) SSL_get1_session() is like SSL_get_session(), but increments
the reference count in the SSL_SESSION returned.
This corrects the reference count handling in SSL_get_session. Previously, the returned SSL_SESSION didn't have its reference count incremented so the SSL_SESSION could be freed at any time causing seg-faults if the pointer was subsequently used. Code that uses SSL_get_session must now make a corresponding SSL_SESSION_free() call when it is done to avoid memory leaks (or blocked up session caches). Submitted By: Geoff Thorpe <geoff@eu.c2.net>

[Steve Henson]
Fix to the -revoke option in ca. It was leaking memory, crashing and just plain not working :-( Also fix some memory leaks in the new X509_NAME code. Fix so new app_rand code doesn't crash 'x509' and move #include so it compiles under Win32.
1999-11-08 13:58:08 +00:00
*) Fix the -revoke option in ca. It was freeing up memory twice,
leaking and not finding already revoked certificates.

Allow additional information to be attached to a certificate: currently this includes trust settings and a "friendly name".
1999-11-04 00:45:35 +00:00
*) Extensive changes to support certificate auxiliary information.
This involves the use of X509_CERT_AUX structure and X509_AUX
functions. An X509_AUX function such as PEM_read_X509_AUX()
can still read in a certificate file in the usual way but it
will also read in any additional "auxiliary information". By

retained: existing certificates can have this information added

Current auxiliary information includes an "alias" and some trust
settings. The trust settings will ultimately be used in enhanced
certificate chain verification routines: currently a certificate
can only be trusted if it is self signed and then it is trusted
for all purposes.

Fix to PKCS#7 routines so it can decrypt some oddball RC2 handling.
1999-10-29 13:06:25 +00:00
*) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
handling. Most clients have the effective key size in bits equal to
the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
A few however don't do this and instead use the size of the decrypted key
to determine the RC2 key length and the AlgorithmIdentifier to determine

the effective key length. In this case the effective key length can still

1999-10-29 13:06:25 +00:00
be 40 bits but the key length can be 168 bits for example. This is fixed
by manually forcing an RC2 key into the EVP_PKEY structure because the
EVP code can't currently handle unusual RC2 key sizes: it always assumes
the key length and effective key length are equal.
[Steve Henson]
Continued multibyte character support. Add a bunch of functions to simplify the creation of X509_NAME structures. Change the X509_NAME_entry_add stuff in req/ca so it no longer uses X509_NAME_entry_count(): passing -1 has the same effect.
1999-10-27 00:15:11 +00:00
*) Add a bunch of functions that should simplify the creation of
X509_NAME structures. Now you should be able to do:
X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
and have it automatically work out the correct field type and fill in
the structures. The more adventurous can try:
X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
and it will (hopefully) work out the correct multibyte encoding.
[Steve Henson]
*) Change the 'req' utility to use the new field handling and multibyte
copy routines. Before the DN field creation was handled in an ad hoc
way in req, ca, and x509 which was rather broken and didn't support
BMPStrings or UTF8Strings. Since some software doesn't implement
BMPStrings or UTF8Strings yet, they can be enabled using the config file
using the dirstring_type option. See the new comment in the default

Make md_rand.c more robust.
1999-10-26 14:49:12 +00:00
*) Make crypto/rand/md_rand.c more robust:
Always hash the pid in the first iteration in ssleay_rand_bytes, don't try to detect fork()s by looking at getpid(). The reason is that threads sharing the same memory can have different PIDs; it's inefficient to run RAND_seed each time a different thread calls RAND_bytes.

- Assure unique random numbers after fork().
Make md_rand.c more robust.
1999-10-26 14:49:12 +00:00
- Make sure that concurrent threads access the global counter and
md serializably so that we never lose entropy in them
or use exactly the same state in multiple threads.
Access to the large state is not always serializable because
the additional locking could be a performance killer, and
md should be large enough anyway.

New function ASN1_mbstring_copy() to handle ASN1 string copying. Ultimately this will be used to clear up the horrible DN mess.
1999-10-21 13:20:49 +00:00
*) New function ASN1_mbstring_copy() this copies a string in either
ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
into an ASN1_STRING type. A mask of permissible types is passed
and it chooses the "minimal" type to use or an error if not type
is suitable.
[Steve Henson]
Replace the macros in asn1.h with function equivalents. Also make UTF8Strings tolerated in certificates.
1999-10-20 01:50:23 +00:00
*) Add function equivalents to the various macros in asn1.h. The old
macros are retained with an M_ prefix. Code inside the library can
use the M_ macros. External code (including the openssl utility)
should *NOT* in order to be "shared library friendly".
[Steve Henson]
Initial support for certificate purpose checking: this will ultimately lead to certificate chain verification. It is VERY EXPERIMENTAL at present though.
1999-10-13 01:11:56 +00:00
*) Add various functions that can check a certificate's extensions
to see if it usable for various purposes such as SSL client,
server or S/MIME and CAs of these types. This is currently
VERY EXPERIMENTAL but will ultimately be used for certificate chain
verification. Also added a -purpose flag to x509 utility to
print out all the purposes.
[Steve Henson]
Add EX_DATA support to X509. Fix a bug in the X509_get_d2i() functions which didn't check if crit was NULL.

for, obtain and decode and extension and obtain its critical flag.
This allows all the necessary extension code to be handled in a
single function call.

New option -dhparam to s_server to allow the DH parameter file to be set explicitly. Previously it couldn't be changed because it was hard coded as "server.pem".
1999-10-04 23:56:06 +00:00
*) New option -dhparam in s_server. This allows a DH parameter file to be
stated explicitly. If it is not stated then it tries the first server
certificate file. The previous behaviour hard coded the filename
"server.pem".
[Steve Henson]
Add support for public key input and output in rsa and dsa utilities with some new DSA public key functions that were missing. Also beginning of a cache for X509_EXTENSION structures: this will allow them to be accessed more quickly for things like certificate chain verification...
1999-10-04 21:17:47 +00:00
*) Add -pubin and -pubout options to the rsa and dsa commands. These allow
a public key to be input or output. For example:
openssl rsa -in key.pem -pubout -out pubkey.pem
Also added necessary DSA public key functions to handle this.
[Steve Henson]
Fix for d2i_ASN1_bytes and stop PKCS#7 routines crashing is signed message contains no certificates. Also fix typo in RANLIB changes.
1999-10-04 12:08:59 +00:00
*) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
in the message. This was handled by allowing
X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
[Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
*) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
to the end of the strings whereas this didn't. This would cause problems
if strings read with d2i_ASN1_bytes() were later modified.
[Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
Fix for base64 BIO decoding bug
1999-10-02 13:33:06 +00:00
*) Fix for base64 decode bug. When a base64 bio reads only one line of
data and it contains EOF it will end up returning an error. This is
caused by input 46 bytes long. The cause is due to the way base64
BIOs find the start of base64 encoded data. They do this by trying a
trial decode on each line until they find one that works. When they
do a flag is set and it starts again knowing it can pass all the
data directly through the decoder. Unfortunately it doesn't reset
the context it uses. This means that if EOF is reached an attempt
is made to pass two EOFs through the context and this causes the
resulting error. This can also cause other problems as well. As is
usual with these problems it takes *ages* to find and the fix is
trivial: move one line.
[Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
Fix to make s_client and s_server work under Windows. A bit of a hack but an improvement on not working at all.
1999-09-20 22:09:17 +00:00
*) Ugly workaround to get s_client and s_server working under Windows. The
old code wouldn't work because it needed to select() on sockets and the
tty (for keypresses and to see if data could be written). Win32 only
supports select() on sockets so we select() with a 1s timeout on the
sockets and then see if any characters are waiting to be read, if none
are present then we retry, we also assume we can always write data to
the tty. This isn't nice because the code then blocks until we've
received a complete line of data and it is effectively polling the
keyboard at 1s intervals: however it's quite a bit better than not
working at all :-) A dedicated Windows application might handle this
with an event loop for example.
[Steve Henson]
Add new sign and verify members to RSA_METHOD and change SSL code to use sign and verify rather than direct encrypt/decrypt.
1999-09-18 22:37:44 +00:00
*) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
will be called when RSA_sign() and RSA_verify() are used. This is useful
if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
should *not* be used: RSA_sign() and RSA_verify() must be used instead.
This necessitated the support of an extra signature type NID_md5_sha1
for SSL signatures and modifications to the SSL library to use it instead
of calling RSA_public_decrypt() and RSA_private_encrypt().
[Steve Henson]
Various CRL enhancements tidies and workaround for broken CRLs.

some more patches for avoiding problems with non-automatic variables
1999-09-08 21:58:13 +00:00
*) Initialize all non-automatic variables each time one of the openssl

multiple times from the "OpenSSL>" prompt).
[Lennart Bang, Bodo Moeller]
This is preliminary support for an "RSA null" cipher. Unfortunately when OpenSSL is compiled with NO_RSA, no RSA operations can be used: including key generation storage and display of RSA keys. Since these operations are not covered by the RSA patent (my understanding is it only covers encrypt, decrypt, sign and verify) they can be included: this is an often requested feature, attempts to use the patented operations return an error code. This is enabled by setting RSA_NULL. This means that if a particular application has its own legal US RSA implementation then it can use that instead by setting it as the default RSA method. Still experimental and needs some fiddling of the other libraries so they have some options that don't attempt to use RSA if it isn't allowed.
1999-09-08 18:02:25 +00:00
*) Preliminary compilation option RSA_NULL which disables RSA crypto without
removing all other RSA functionality (this is what NO_RSA does). This
is so (for example) those in the US can disable those operations covered
by the RSA patent while allowing storage and parsing of RSA keys and RSA
key generation.

Add new 'spkac' utility and several SPKAC utility functions.
1999-09-03 01:08:34 +00:00

handled by poking round in the structure internals. Added new function
NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
print, verify and generate SPKACs. Based on an original idea from
Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.

Allow the extension section specified in config files to be overridden on the command line for various utilities.
1999-08-27 00:08:17 +00:00
*) Allow the config file extension section to be overwritten on the
command line. Based on an original idea from Massimiliano Pala
<madwolf@comune.modena.it>. The new option is called -extensions
and can be applied to ca, req and x509. Also -reqexts to override
the request extensions in req and -crlexts to override the crl extensions
in ca.
[Steve Henson]
Allow the 1.OU="my OU" syntax in 'ca' for SPKACs.
1999-08-25 23:18:23 +00:00
*) Add new feature to the SPKAC handling in ca. Now you can include
the same field multiple times by preceding it by "XXXX." for example:
1.OU="Unit name 1"
2.OU="Unit name 2"
this is the same syntax as used in the req config file.
[Steve Henson]
Allow extensions to be added to certificate requests, update the sample config file (change RAW to DER).
1999-08-25 16:59:26 +00:00
*) Allow certificate extensions to be added to certificate requests. These
are specified in a 'req_extensions' option of the req section of the
config file. They can be printed out with the -text option to req but
are otherwise ignored at present.

Initial support for DH_METHOD. Also added a DH lock. A few changes made to DSA_METHOD to make it more consistent with RSA_METHOD.
1999-08-23 23:11:32 +00:00
*) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
a few extra parameters to the DH structure: these will be useful if
for example we want the value of 'q' or implement X9.42 DH.
[Steve Henson]
Initial support for DSA_METHOD...
1999-08-22 17:57:38 +00:00
*) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
provides hooks that allow the default DSA functions or functions on a
"per key" basis to be replaced. This allows hardware acceleration and
hardware key storage to be handled without major modification to the
library. Also added low level modexp hooks and CRYPTO_EX structure and
associated functions.

as "read only": it can't be written to and the buffer it points to will
not be freed. Reading from a read only BIO is much more efficient than
a normal memory BIO. This was added because there are several times when
an area of memory needs to be read from a BIO. The previous method was
to create a memory BIO and write the data to it, this results in two
copies of the data and an O(n^2) reading algorithm. There is a new
function BIO_new_mem_buf() which creates a read only memory BIO from
an area of memory. Also modified the PKCS#7 routines to use read only

Fix horrible (and hard to track down) bug in ssl23_get_client_hello: In case of a restart, v[0] and v[1] were incorrectly initialised. This was interpreted by ssl3_get_client_key_exchange as an RSA decryption failure (don't ask me why) and caused it to create a _random_ master key instead (even weirder), which obviously led to incorrect input to ssl3_generate_master_secret and thus caused "block cipher pad is wrong" error messages from ssl3_enc for the client's Finished message. Arrgh.
1999-08-18 17:14:42 +00:00
*) Bugfix: ssl23_get_client_hello did not work properly when called in
state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
but a retry condition occured while trying to read the rest.

Fix PKCS7_ENC_CONTENT_new() to include a sensible default content type and add support for encrypted content type in PKCS7_set_content().
1999-08-17 12:58:01 +00:00
*) The PKCS7_ENC_CONTENT_new() function was setting the content type as
NID_pkcs7_encrypted by default: this was wrong since this should almost
always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
the encrypted data type: this is a more sensible place to put it and it
allows the PKCS#12 code to be tidied up that duplicated this
functionality.

New function DSA_dup_DH, and fixes for bugs that were found while implementing and using it.
1999-08-05 11:50:18 +00:00
*) New function DSA_dup_DH, which duplicates DSA parameters/keys as
DH parameters/keys (q is lost during that conversion, but the resulting
DH parameters contain its length).
For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
much faster than DH_generate_parameters (which creates parameters
where p = 2*q + 1), and also the smaller q makes DH computations
much more efficient (160-bit exponentiation instead of 1024-bit
exponentiation); so this provides a convenient way to support DHE
ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
utter importance to use
SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
or
SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
when such DH parameters are used, because otherwise small subgroup
attacks may become possible!

1999-07-21 20:57:16 +00:00
New function SSL_CTX_set_default_passwd_cb_userdata.
Compatibility note: As many C implementations push function arguments
onto the stack in reverse order, the new library version is likely to
interoperate with programs that have been compiled with the old
pem_password_cb definition (PEM_whatever takes some data that
happens to be on the stack as its last argument, and the callback
just ignores this garbage); but there is no guarantee whatsoever that
this will work.

Fix a bug in x509.c that omitted DSA parameters when they didn't match the signers parameters. Changed it to never omit parameters.
1999-07-11 01:48:21 +00:00
*) The x509 application mishandled signing requests containing DSA
keys when the signing key was also DSA and the parameters didn't match.
It was supposed to omit the parameters when they matched the signing key:
the verifying software was then supposed to automatically use the CA's
parameters if they were absent from the end user certificate.
Omitting parameters is no longer recommended. The test was also
the wrong way round! This was probably due to unusual behaviour in
EVP_cmp_parameters() which returns 1 if the parameters match.
This meant that parameters were omitted when they *didn't* match and
the certificate was useless. Certificates signed with 'ca' didn't have
this bug.

Have CRYPTO_MDEBUG_TIME automatically set CRYPTO_MDEBUG, and make it the default for some debugging configurations.

The interface is as follows:
Fix memory checking.

Applications can use
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),

"off" is now the default.
The library internally uses
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
to disable memory-checking temporarily.
Some inconsistent states that previously were possible (and were
even the default) are now avoided.

1999-07-19 09:25:35 +00:00
-DCRYPTO_MDEBUG_TIME is new and additionally stores the current time

1999-07-02 13:55:32 +00:00
*) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
which largely parallels "options", but is for changing API behaviour,
whereas "options" are about protocol behaviour.
SSL_MODE_ENABLE_PARTIAL_WRITE and SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER work as intended, both for SSLv2 and TLS.

Fix d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() so it correctly works out the length of negative integers.
1999-06-24 01:50:27 +00:00
*) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
up the length of negative integers. This has now been simplified to just
store the length when it is first determined and use it later, rather
than trying to keep track of where data is copied and updating it to
point to the end.

New function PKCS7_signatureVerify to allow the signing certificate to be explicitly stated with PKCS#7 verify. Also fix for util/mkerr.pl: if the -nostatic option is being used this will be for an external library so the autogenerated C file should include the header file as: #include "any/path/to/header.h" rather than the internal library form: #include <openssl/header.h>
1999-06-22 13:33:22 +00:00
*) Add a new function PKCS7_signatureVerify. This allows the verification
of a PKCS#7 signature but with the signing certificate passed to the
function itself. This contrasts with PKCS7_dataVerify which assumes the
certificate is present in the PKCS#7 structure. This isn't always the
case: certificates can be omitted from a PKCS#7 structure and be
distributed by "out of band" means (such as a certificate database).

fails, it needs to cause bc to give a non-zero result or make test carries
on without noticing the failure. Fixed.

Rewrite PBE handling read to support PKCS#5 v2.0 and update the function list for Win32.
1999-06-06 13:07:13 +00:00
*) Rewrite the way password based encryption (PBE) is handled. It used to
assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
the 'parameter' field of the AlgorithmIdentifier is passed to the
underlying key generation function so it must do its own ASN1 parsing.
This has also changed the EVP_PBE_CipherInit() function which now has a
'parameter' argument instead of literal salt and iteration count values
and the function EVP_PBE_ALGOR_CipherInit() has been deleted.

New functions sk_set, sk_value and sk_num to replace existing macros: this is to minimise the effects on existing code.
1999-05-19 12:45:16 +00:00
*) New functions sk_num, sk_value and sk_set to replace the previous macros.
These are required because of the typesafe stack would otherwise break
existing code. If old code used a structure member which used to be STACK
and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
sk_num or sk_value it would produce an error because the num, data members
are not present in STACK_OF. Now it just produces a warning. sk_set
replaces the old method of assigning a value to sk_value
(e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
that does this will no longer work (and should use sk_set instead) but
this could be regarded as a "questionable" behaviour anyway.
[Steve Henson]
Fix various less obvious bugs in PKCS#7 handling: such as not zeroing the secret key before we've encrypted it and using the right NID for RC2-64.

Fix some obvious bugs in the PKCS#7 library handling. It didn't try to find the right RecipientInfo based on the recipient certificate (so would fail a lot of the time) and fixup cipher structures to correctly (maybe) modify the AlgorithmIdentifiers. Largely untested at present... this will be fixed in due course. Well the stuff was broken to begin with so if its broken now then you haven't lost anything :-)
1999-05-16 00:25:36 +00:00
*) Reorganise the PKCS#7 library and get rid of some of the more obvious
problems: find RecipientInfo structure that matches recipient certificate
and initialise the ASN1 structures properly based on passed cipher.

Create a duplicate of the SSL_CTX's CERT in SSL_new instead of copying pointers. The cert_st handling is changed by this in various ways. Submitted by: Reviewed by: PR:
1999-05-09 20:12:44 +00:00
*) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
copying pointers. The cert_st handling is changed by this in
various ways (and thus what used to be known as ctx->default_cert
is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
any longer when s->cert does not give us what we need).
ssl_cert_instantiate becomes obsolete by this change.
As soon as we've got the new code right (possibly it already is?),
we have solved a couple of bugs of the earlier code where s->cert
was used as if it could not have been shared with other SSL structures.
Note that using the SSL API in certain dirty ways now will result
in different behaviour than observed with earlier library versions:
Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
does not influence s as it used to.
In order to clean up things more thoroughly, inside SSL_SESSION
New structure type SESS_CERT used instead of CERT inside SSL_SESSION. While modifying the sources, I found some inconsistencies on the use of s->cert vs. s->session->sess_cert; I don't know if those could really have caused problems, but possibly this is a proper bug-fix and not just a clean-up.

Complete rewrite of the error code generation script. It now runs as a single script, translates function codes better and doesn't need the K&R function prototypes to work (NB. the K&R prototypes can't be wiped just yet: they are still needed by the DEF generator...). I also ran the script with the -rewrite option to update all the header and source files.

Add a useful kludge to allow package maintainers to specify compiler and other platforms details on the command line without having to patch the Configure script everytime: One now can use ``perl Configure <id>:<details>'', i.e. platform ids are allowed to have details appended to them (seperated by colons). This is treated as there would be a static pre-configured entry in Configure's %table under key <id> with value <details> and ``perl Configure <id>'' is called. So, when you want to perform a quick test-compile under FreeBSD 3.1 with pgcc and without assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"'' now, which overrides the FreeBSD-elf entry on-the-fly. (PS: Notice that the same effect _cannot_ be achieved by using ``make CC=pgcc ..'' etc, because you cannot override all things from there.)

and add an extra 'crl' parameter in the X509V3_CTX structure: guess
what that's for :-) Fix to ASN1 macro which messed up
IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.

now reads in the old error codes and retains the old numbers, only
adding new ones if necessary. It also only changes the .err files if new
codes are added. The makefiles have been modified to only insert errors
when needed (to avoid needlessly modifying header files). This is done
by only inserting errors if the .err file is newer than the auto generated
C file. To rebuild all the error codes from scratch (the old behaviour)
either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
or delete all the .err files.

[The OpenSSL Project]
Various cleanups and fixed by Marc and Ralf to start the OpenTLS project
1998-12-22 15:04:48 +00:00
Add release dates to the "CHANGES" file, because that's an obvious place to look for them.

Changes between 0.9.0b and 0.9.1b [not released]
Various cleanups and fixed by Marc and Ralf to start the OpenTLS project
1998-12-22 15:04:48 +00:00
*) Updated a few CA certificates under certs/
[Eric A. Young]
*) Changed some BIGNUM api stuff.
[Eric A. Young]
*) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
DGUX x86, Linux Alpha, etc.
[Eric A. Young]
*) New COMP library [crypto/comp/] for SSL Record Layer Compression:
RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
available).
[Eric A. Young]
*) Add -strparse option to asn1pars program which parses nested
binary structures
[Dr Stephen Henson <shenson@bigfoot.com>]
*) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
[Eric A. Young]
*) DSA fix for "ca" program.
[Eric A. Young]
*) Added "-genkey" option to "dsaparam" program.
[Eric A. Young]
*) Added RIPE MD160 (rmd160) message digest.
[Eric A. Young]
*) Added -a (all) option to "ssleay version" command.
[Eric A. Young]
*) Added PLATFORM define which is the id given to Configure.
[Eric A. Young]
*) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
[Eric A. Young]
*) Extended the ASN.1 parser routines.
[Eric A. Young]
*) Extended BIO routines to support REUSEADDR, seek, tell, etc.
[Eric A. Young]
*) Added a BN_CTX to the BN library.
[Eric A. Young]
*) Fixed the weak key values in DES library
[Eric A. Young]
*) Changed API in EVP library for cipher aliases.
[Eric A. Young]
*) Added support for RC2/64bit cipher.
[Eric A. Young]
*) Converted the lhash library to the crypto/mem.c functions.
[Eric A. Young]
*) Added more recognized ASN.1 object ids.
[Eric A. Young]
*) Added more RSA padding checks for SSL/TLS.
[Eric A. Young]
*) Added BIO proxy/filter functionality.
[Eric A. Young]
*) Added extra_certs to SSL_CTX which can be used
send extra CA certificates to the client in the CA cert chain sending
process. It can be configured with SSL_CTX_add_extra_chain_cert().
[Eric A. Young]
*) Now Fortezza is denied in the authentication phase because
this is key exchange mechanism is not supported by SSLeay at all.
[Eric A. Young]
*) Additional PKCS1 checks.
[Eric A. Young]
*) Support the string "TLSv1" for all TLS v1 ciphers.
[Eric A. Young]
*) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
ex_data index of the SSL context in the X509_STORE_CTX ex_data.
[Eric A. Young]
*) Fixed a few memory leaks.
[Eric A. Young]
*) Fixed various code and comment typos.
[Eric A. Young]
*) A minor bug in ssl/s3_clnt.c where there would always be 4 0
bytes sent in the client random.
