94a209d8e1 Add ctrl and utility functions to retrieve raw cipher list sent by client in 
client hello message. Previously this could only be retrieved on an initial
connection and it was impossible to determine the cipher IDs of any uknown
ciphersuites.

e5db9c3b67 Minor enhancement to PR#2836 fix. Instead of modifying SSL_get_certificate 
change the current certificate (in s->cert->key) to the one used and then
SSL_get_certificate and SSL_get_privatekey will automatically work.

74ecfab401 Add support for certificate stores in CERT structure. This makes it 
possible to have different stores per SSL structure or one store in
the parent SSL_CTX. Include distint stores for certificate chain
verification and chain building. New ctrl SSL_CTRL_BUILD_CERT_CHAIN
to build and store a certificate chain in CERT structure: returing
an error if the chain cannot be built: this will allow applications
to test if a chain is correctly configured.

Note: if the CERT based stores are not set then the parent SSL_CTX
store is used to retain compatibility with existing behaviour.

b7bfe69b66 New function ssl_set_client_disabled to set masks for any ciphersuites 
that are disabled for this session (as opposed to always disabled by
configuration).

Dr. Stephen Henson
9f27b1eec3 Add new ctrl to retrieve client certificate types, print out 
details in s_client.

Also add ctrl to set client certificate types. If not used sensible values
will be included based on supported signature algorithms: for example if
we don't include any DSA signing algorithms the DSA certificate type is
omitted.

Fix restriction in old code where certificate types would be truncated
if it exceeded TLS_CT_NUMBER.

3dbc46dfcd Separate client and server permitted signature algorithm support: by default 
the permitted signature algorithms for server and client authentication
are the same but it is now possible to set different algorithms for client
authentication only.
 2012-07-03 12:51:14 +00:00
Dr. Stephen Henson
18d7158809 Add certificate callback. If set this is called whenever a certificate 
is required by client or server. An application can decide which
certificate chain to present based on arbitrary criteria: for example
supported signature algorithms. Add very simple example to s_server.
This fixes many of the problems and restrictions of the existing client
certificate callback: for example you can now clear existing certificates
and specify the whole chain.
 2012-06-29 14:24:42 +00:00
Dr. Stephen Henson
d61ff83be9 Add new "valid_flags" field to CERT_PKEY structure which determines what 
the certificate can be used for (if anything). Set valid_flags field
in new tls1_check_chain function. Simplify ssl_set_cert_masks which used
to have similar checks in it.

Add new "cert_flags" field to CERT structure and include a "strict mode".
This enforces some TLS certificate requirements (such as only permitting
certificate signature algorithms contained in the supported algorithms
extension) which some implementations ignore: this option should be used
with caution as it could cause interoperability issues.

5863163732 Additional compatibility fix for MDC2 signature format. 
Update RSA EVP_PKEY_METHOD to use the OCTET STRING form of MDC2 signature:
this will make all versions of MDC2 signature equivalent.
 2012-02-15 14:27:25 +00:00
Dr. Stephen Henson
83cb7c4635 An incompatibility has always existed between the format used for RSA 
signatures and MDC2 using EVP or RSA_sign. This has become more apparent
when the dgst utility in OpenSSL 1.0.0 and later switched to using the
EVP_DigestSign functions which call RSA_sign.

This means that the signature format OpenSSL 1.0.0 and later used with
dgst -sign and MDC2 is incompatible with previous versions.

Add detection in RSA_verify so either format works.

Note: MDC2 is disabled by default in OpenSSL and very rarely used in practice.

e66cb363d6 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).

new signature format is not yet implemented.

08557cf22c Initial "opaque SSL" framework. If an application defines 
OPENSSL_NO_SSL_INTERN all ssl related structures are opaque
and internals cannot be directly accessed. Many applications
will need some modification to support this and most likely some
additional functions added to OpenSSL.

The advantage of this option is that any application supporting
it will still be binary compatible if SSL structures change.

05e24c87dd 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.
