*) Memory leak checking had some problems. The interface is as follows:
Applications can use
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
"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.
[Bodo Moeller]
*) 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.
Initial "mode" flags (still experimental) are:
SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
a single record has been written.
SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
retries use the same buffer location.
(But all of the contents must be
copied!)
[Bodo Moeller]
*) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode
worked.
*) Fix problems with no-hmac etc.

*) New functions RSA_get_default_method(), RSA_set_method() and
RSA_get_method(). These allows replacement of RSA_METHODs without having
to mess around with the internals of an RSA structure.
[Steve Henson]
*) Fix memory leaks in DSA_do_sign and DSA_is_prime.
Also really enable memory leak checks in openssl.c and in some
test programs.

*) 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.
[Steve Henson, reported by Brien Wheeler
<bwheeler@authentica-security.com>]
*) 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).

*) Complete the PEM_* macros with DECLARE_PEM versions to replace the
function prototypes in pem.h, also change util/mkdef.pl to add the
necessary function names.
[Steve Henson]
*) mk1mf.pl (used by Windows builds) did not properly read the
options set by Configure in the top level Makefile, and Configure
was not even able to write more than one option correctly.
Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
Dr. Stephen Henson
committed
*) New functions CONF_load_bio() and CONF_load_fp() to allow a config
file to be loaded from a BIO or FILE pointer. The BIO version will
for example allow memory BIOs to contain config info.
[Steve Henson]
*) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
Whoever hopes to achieve shared-library compatibility across versions
must use this, not the compile-time macro.
(Exercise 0.9.4: Which is the minimum library version required by
such programs?)
Note: All this applies only to multi-threaded programs, others don't
need locks.
*) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
through a BIO pair triggered the default case, i.e.
SSLerr(...,SSL_R_UNKNOWN_STATE).
[Bodo Moeller]
*) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
can use the SSL library even if none of the specific BIOs is
appropriate.
[Bodo Moeller]
*) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
for the encoded length.

*) Add initial documentation of the X509V3 functions.

*) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
PEM_write_bio_PKCS8PrivateKey() that are equivalent to
PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
secure PKCS#8 private key format with a high iteration count.
[Steve Henson]
*) Fix determination of Perl interpreter: A perl or perl5
_directory_ in $PATH was also accepted as the interpreter.
[Ralf S. Engelschall]
*) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
wrong with it but it was very old and did things like calling
PEM_ASN1_read() directly and used MD5 for the hash not to mention some
unusual formatting.
[Steve Henson]
Dr. Stephen Henson
committed
*) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
to use the new extension code.
[Steve Henson]
*) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
with macros. This should make it easier to change their form, add extra
arguments etc. Fix a few PEM prototypes which didn't have cipher as a
constant.
[Steve Henson]
*) Add to configuration table a new entry that can specify an alternative
name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
according to Mark Crispin <MRC@Panda.COM>.
[Bodo Moeller]
*) DES CBC did not update the IV. Weird.
[Ben Laurie]
des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
Changing the behaviour of the former might break existing programs --
where IV updating is needed, des_ncbc_encrypt can be used.
*) When bntest is run from "make test" it drives bc to check its
calculations, as well as internally checking them. If an internal check
fails, it needs to cause bc to give a non-zero result or make test carries
on without noticing the failure. Fixed.
[Ben Laurie]
*) DES library cleanups.
[Ulf Möller]
*) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
ciphers. NOTE: although the key derivation function has been verified
against some published test vectors it has not been extensively tested
yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
of v2.0.
[Steve Henson]
*) Instead of "mkdir -p", which is not fully portable, use new
Perl script "util/mkdir-p.pl".
Dr. Stephen Henson
committed
*) 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.
[Steve Henson]
Dr. Stephen Henson
committed
*) Support for PKCS#5 v1.5 compatible password based encryption algorithms
and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
KEY" because this clashed with PKCS#8 unencrypted string. Since this
value was just used as a "magic string" and not used directly its
value doesn't matter.

[Steve Henson]
*) Introduce some semblance of const correctness to BN. Shame C doesn't
support mutable.
[Ben Laurie]
"linux-sparc" configuration.
[Christian Forster <fo@hawo.stw.uni-erlangen.de>]
*) config now generates no-xxx options for missing ciphers.
[Ulf Möller]
*) Support the EBCDIC character set (work in progress).
