Use BUF_strlcat() instead of strcat().
Use BIO_snprintf() instead of sprintf().
In some cases, keep better track of buffer lengths.
This is part of a large change submitted by Markus Friedl <markus@openbsd.org>
I have tried to convert 'len' type variable declarations to unsigned as a
means to address these warnings when appropriate, but when in doubt I have
used casts in the comparisons instead. The better solution (that would get
us all lynched by API users) would be to go through and convert all the
function prototypes and structure definitions to use unsigned variables
except when signed is necessary. The proliferation of (signed) "int" for
strictly non-negative uses is unfortunate.
EVP_PKEY_cmp_parameters() returned 0, otherwise it should
go on processing the public key component. Thia has nothing
to do with the proper handling of EC parameters or not.
Two fixes:
1. If BIO_write() fails inside enc_write() it should return the
total number of bytes successfully written.
2. If BIO_write() fails during BIO_flush() it should return immediately
with the error code: previously it would fall through to the final
encrypt, corrupting the buffer.
when reading from a non blocking BIO.
It would incorrectly interpret retries as EOF, incorrectly
buffer initial data and have no buffering at all after initial
data (data would be sent one byte at a time to EVP_DecodeUpdate).
bad, so let's not check OPENSSL_NO_ENGINE in those places. Fortunately, all
the header files where the problem existed include ossl_typ.h, which makes
a 'forward declaration' of the ENGINE type.
evp.h.
Application authors BEWARE! If you have had the habit to count on
evp.h to provide all those lower-level algorithm functions, you need
to think again! Please change your programs NOW, or you will be sorry
when 0.9.8 gets release (it's quite some time away...).
engine with something they claim is better. I have nothing to compare to,
and I assume they know what they're talking about. The interesting part with
this one is that it's loaded by default on OpenBSD systems.
This change was originally introduced in OpenBSD's tracking of OpenSSL.
(the same keys can be used for ECC schemes other than ECDSA)
and add some new options.
Similarly, use string "EC PARAMETERS" instead of "ECDSA PARAMETERS"
in 'PEM' format.
Fix ec_asn1.c (take into account the desired conversion form).

des_old.h redefines crypt:
#define crypt(b,s)\
DES_crypt((b),(s))
This scheme leads to failure, if header files with the OS's true definition
of crypt() are processed _after_ des_old.h was processed. This is e.g. the
case on HP-UX with unistd.h.
As evp.h now again includes des.h (which includes des_old.h), this problem
only came up after this modification.
Solution: move header files (indirectly) including e_os.h before the header
files (indirectly) including evp.h.

was that they weren't really needed any more for EVP itself. However,
it seems like soma applications (I know about OpenSSH, but there may
be more) used evp.h as the 'load all' header file, which makes sense
since we try our best to promote the use of EVP instead of the lower
level crypto algorithms. Therefore, I put the inclusions back so
the application authors don't get too shocked by all the errors they
would otherwise get.
Thanks to Theo de Raadt for making us aware of this.

algorithms are using. Therefore, let's redo certain EVP macros to
accept different amounts of feedback bits for these modes.
Also, change e_aes.c to provide all usually available modes for AES.

replacement implementation). This change makes sure the correct
implementation's "init()" handler is used rather than assuming 'type'.

from Stephen Sprunk <stephen@sprunk.org> and fiddled it to work
properly with the normal EVP constructs (and incidently work the same
way as all other symmetric cipher implementations).
This results in an API that looks a lot like the rest of the OpenSSL
cipher suite.
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.
The compatibility functions will be removed in some future release, at
the latest in version 1.0.

This also changes the non-"_ex" versions to defer directly to
EVP_CipherInit_ex() rather than EVP_CipherInit() to avoid an unecessary
level of indirection.

- it also removes openbsd_hw.c from the build (that functionality is
going to be available in the openbsd ENGINE in a upcoming commit)
- evp_test has had the extra initialisation added so it will use (if
possible) any ENGINEs supporting the algorithms required.
ENGINE surgery. DH, DSA, RAND, and RSA now use *both* "method" and ENGINE
pointers to manage their hooking with ENGINE. Previously their use of
"method" pointers was replaced by use of ENGINE references. See
crypto/engine/README for details.
Also, remove the ENGINE iterations from evp_test - even when the
cipher/digest code is committed in, this functionality would require a
different set of API calls.
distinction (which does not work well because if CRYPTO_MDEBUG is
defined at library compile time, it is not necessarily defined at
application compile time; and memory debugging now can be reconfigured
at run-time anyway). To get the intended semantics, we could just use
the EVP_DigestInit_dbg unconditionally (which uses the caller's
__FILE__ and __LINE__ for memory leak debugging), but this would make
memory debugging inconsistent. Instead, callers can use
CRYPTO_push_info() to track down memory leaks.

Also fix indentation, and add OpenSSL copyright.
