Changes between 0.9.7a and 0.9.8 [xx XXX xxxx]
*) Add functionality to check the public key of a certificate request
against a given private. This is useful to check that a certificate
request can be signed by that key (self-signing).
[Richard Levitte]
*) Make it possible to have multiple active certificates with the same
subject in the CA index file. This is done only if the keyword
'unique_subject' is set to 'no' in the main CA section (default
if 'CA_default') of the configuration file. The value is saved
with the database itself in a separate index attribute file,
named like the index file with '.attr' appended to the name.
[Richard Levitte]
*) Generate muti valued AVAs using '+' notation in config files for
req and dirName.
[Steve Henson]
*) Support for nameConstraints certificate extension.
[Steve Henson]
*) Support for policyConstraints certificate extension.
[Steve Henson]
*) Support for policyMappings certificate extension.
[Steve Henson]
*) Fixed a typo bug that would cause ENGINE_set_default() to set an
ENGINE as defaults for all supported algorithms irrespective of
the 'flags' parameter. 'flags' is now honoured, so applications
should make sure they are passing it correctly.
[Geoff Thorpe]
*) Make sure the default DSA_METHOD implementation only uses its
dsa_mod_exp() and/or bn_mod_exp() handlers if they are non-NULL,
and change its own handlers to be NULL so as to remove unnecessary
indirection. This lets alternative implementations fallback to the
default implementation more easily.
[Geoff Thorpe]
*) Support for directoryName in GeneralName related extensions
in config files.
[Steve Henson]

*) Make it possible to link applications using Makefile.shared.
Make that possible even when linking against static libraries!
[Richard Levitte]
*) Various fixes to base64 BIO and non blocking I/O. On write
flushes were not handled properly if the BIO retried. On read
data was not being buffered properly and had various logic bugs.
[Steve Henson]
*) Support for single pass processing for S/MIME signing. This now
means that S/MIME signing can be done from a pipe, in addition
cleartext signing (multipart/signed type) is effectively streaming
and the signed data does not need to be all held in memory.
This is done with a new flag PKCS7_STREAM. When this flag is set
PKCS7_sign() only initializes the PKCS7 structure and the actual signing
is done after the data is output (and digests calculated) in
SMIME_write_PKCS7().
[Steve Henson]
*) Add full support for -rpath/-R, both in shared libraries and
applications, at least on the platforms where it's known how
to do it.
[Richard Levitte]
*) In crypto/ec/ec_mult.c, implement fast point multiplication with
will now compute a table of multiples of the generator that
faster (notably in the case of a single point multiplication,
scalar * generator).
[Nils Larsch, Bodo Moeller]
*) IPv6 support for certificate extensions. The various extensions
which use the IP:a.b.c.d can now take IPv6 addresses using the
formats of RFC1884 2.2 . IPv6 addresses are now also displayed
correctly.
[Steve Henson]
*) Added an ENGINE that implements RSA by performing private key
exponentiations with the GMP library. The conversions to and from
GMP's mpz_t format aren't optimised nor are any montgomery forms
cached, and on x86 it appears OpenSSL's own performance has caught up.
However there are likely to be other architectures where GMP could
provide a boost. This ENGINE is not built in by default, but it can be
specified at Configure time and should be accompanied by the necessary
linker additions, eg;
./config -DOPENSSL_USE_GMP -lgmp
[Geoff Thorpe]
*) "openssl engine" will not display ENGINE/DSO load failure errors when
testing availability of engines with "-t" - the old behaviour is
produced by increasing the feature's verbosity with "-tt".
[Geoff Thorpe]
*) ECDSA routines: under certain error conditions uninitialized BN objects
could be freed. Solution: make sure initialization is performed early
enough. (Reported and fix supplied by Nils Larsch <nla@trustcenter.de>
via PR#459)
[Lutz Jaenicke]
*) Key-generation can now be implemented in RSA_METHOD, DSA_METHOD
and DH_METHOD (eg. by ENGINE implementations) to override the normal
software implementations. For DSA and DH, parameter generation can
also be overriden by providing the appropriate method callbacks.
[Geoff Thorpe]
*) 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.
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.
*/
[Geoff Thorpe]
*) Change the ZLIB compression method to be stateful, and make it
available to TLS with the number defined in
draft-ietf-tls-compression-04.txt.
[Richard Levitte]
*) Add the ASN.1 structures and functions for CertificatePair, which
is defined as follows (according to X.509_4thEditionDraftV6.pdf):
CertificatePair ::= SEQUENCE {
forward [0] Certificate OPTIONAL,
reverse [1] Certificate OPTIONAL,
-- at least one of the pair shall be present -- }
Also implement the PEM functions to read and write certificate
pairs, and defined the PEM tag as "CERTIFICATE PAIR".
This needed to be defined, mostly for the sake of the LDAP
attribute crossCertificatePair, but may prove useful elsewhere as
well.
[Richard Levitte]
*) Make it possible to inhibit symlinking of shared libraries in
Makefile.shared, for Cygwin's sake.
[Richard Levitte]
*) Extend the BIGNUM API by creating new macros that behave like
functions
void BN_set_sign(BIGNUM *a, int neg);
int BN_get_sign(const BIGNUM *a);
and avoid the need to access 'a->neg' directly in applications.
[Nils Larsch <nla@trustcenter.de>]
*) Implement fast modular reduction for pseudo-Mersenne primes
used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c).
EC_GROUP_new_curve_GFp() will now automatically use this
if applicable.
[Nils Larsch <nla@trustcenter.de>]
*) Add new lock type (CRYPTO_LOCK_BN).
[Bodo Moeller]
*) Change the ENGINE framework to automatically load engines
dynamically from specific directories unless they could be
found to already be built in or loaded. Move all the
current engines except for the cryptodev one to a new
directory engines/.
The engines in engines/ are built as shared libraries if
the "shared" options was given to ./Configure or ./config.
Otherwise, they are inserted in libcrypto.a.
/usr/local/ssl/engines is the default directory for dynamic
engines, but that can be overriden at configure time through
the usual use of --prefix and/or --openssldir, and at run
time with the environment variable OPENSSL_ENGINES.
