*) Add a function EC_GROUP_check_discriminant() (defined via
EC_METHOD) that verifies that the curve discriminant is non-zero.
Add a function EC_GROUP_check() that makes some sanity tests
on a EC_GROUP, its generator and order. This includes
EC_GROUP_check_discriminant().
[Nils Larsch <nla@trustcenter.de>]
*) Add ECDSA in new directory crypto/ecdsa/.
Add applications 'openssl ecdsaparam' and 'openssl ecdsa'
(these are variants of 'openssl dsaparam' and 'openssl dsa').
ECDSA support is also included in various other files across the
library. Most notably,
- 'openssl req' now has a '-newkey ecdsa:file' option;
- EVP_PKCS82PKEY (crypto/evp/evp_pkey.c) now can handle ECDSA;
- X509_PUBKEY_get (crypto/asn1/x_pubkey.c) and
d2i_PublicKey (crypto/asn1/d2i_pu.c) have been modified to make
them suitable for ECDSA where domain parameters must be
extracted before the specific public key.
*) Include some named elliptic curves, and add OIDs from X9.62,
SECG, and WAP/WTLS. The curves can be obtained from the new
functions
EC_GROUP_new_by_nid()
EC_GROUP_new_by_name()
Also add a 'nid' field to EC_GROUP objects, which can be accessed
via
EC_GROUP_set_nid()
EC_GROUP_get_nid()

Changes between 0.9.6 and 0.9.7 [xx XXX 2002]
OpenSSL 0.9.6a/0.9.6b/0.9.6c/0.9.6d (bugfix releases, 5 Apr 2001,
9 July 2001, 21 Dec 2001 and xx XXX 2002) and OpenSSL 0.9.7 were
developed in parallel, based on OpenSSL 0.9.6.
Change log entries are tagged as follows:
-) applies to 0.9.6a ... 0.9.6d only
*) applies to 0.9.6a ... 0.9.6d and 0.9.7
+) applies to 0.9.7 only
*) 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]
+) Add an "init" command to the ENGINE config module and auto initialize
ENGINEs. Without any "init" command the ENGINE will be initialized
after all ctrl commands have been executed on it. If init=1 the
ENGINE is initailized at that point (ctrls before that point are run
on the uninitialized ENGINE and after on the initialized one). If
init=0 then the ENGINE will not be iniatialized at all.
[Steve Henson]
+) Fix the 'app_verify_callback' interface so that the user-defined
argument is actually passed to the callback: In the
SSL_CTX_set_cert_verify_callback() prototype, the callback
declaration has been changed from
int (*cb)()
into
int (*cb)(X509_STORE_CTX *,void *);
in ssl_verify_cert_chain (ssl/ssl_cert.c), the call
i=s->ctx->app_verify_callback(&ctx)
has been changed into
i=s->ctx->app_verify_callback(&ctx, s->ctx->app_verify_arg).
To update applications using SSL_CTX_set_cert_verify_callback(),
a dummy argument can be added to their callback functions.
[D. K. Smetters <smetters@parc.xerox.com>]
+) Added the '4758cca' ENGINE to support IBM 4758 cards.
[Maurice Gittens <maurice@gittens.nl>, touchups by Geoff Thorpe]
*) Fix bug in SSL_clear(): bad sessions were not removed (found by
Yoram Zahavi <YoramZ@gilian.com>).
[Lutz Jaenicke]
+) Add and OPENSSL_LOAD_CONF define which will cause
OpenSSL_add_all_algorithms() to load the openssl.cnf config file.
This allows older applications to transparently support certain
OpenSSL features: such as crypto acceleration and dynamic ENGINE loading.
Two new functions OPENSSL_add_all_algorithms_noconf() which will never
load the config file and OPENSSL_add_all_algorithms_conf() which will
always load it have also been added.
[Steve Henson]
+) Add the OFB, CFB and CTR (all with 128 bit feedback) to AES.
Adjust NIDs and EVP layer.
[Stephen Sprunk <stephen@sprunk.org> and Richard Levitte]
+) Config modules support in openssl utility.
Most commands now load modules from the config file,
though in a few (such as version) this isn't done
because it couldn't be used for anything.
In the case of ca and req the config file used is
the same as the utility itself: that is the -config
command line option can be used to specify an
alternative file.
[Steve Henson]
+) Move default behaviour from OPENSSL_config(). If appname is NULL
use "openssl_conf" if filename is NULL use default openssl config file.
[Steve Henson]
+) Add an argument to OPENSSL_config() to allow the use of an alternative
config section name. Add a new flag to tolerate a missing config file
and move code to CONF_modules_load_file().
[Steve Henson]
*) 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]
+) Support for crypto accelerator cards from Accelerated Encryption
Processing, www.aep.ie. (Use engine 'aep')
The support was copied from 0.9.6c [engine] and adapted/corrected
to work with the new engine framework.
[AEP Inc. and Richard Levitte]
+) Support for SureWare crypto accelerator cards from Baltimore
Technologies. (Use engine 'sureware')
The support was copied from 0.9.6c [engine] and adapted
to work with the new engine framework.
[Richard Levitte]
*) Have ASN1_BIT_STRING_set_bit() really clear a bit when the requested
value is 0.
[Richard Levitte]
+) Have the CHIL engine fork-safe (as defined by nCipher) and actually
make the newer ENGINE framework commands for the CHIL engine work.
[Toomas Kiisk <vix@cyber.ee> and Richard Levitte]
+) Make it possible to produce shared libraries on ReliantUNIX.

*) Add the configuration target linux-s390x.
[Neale Ferguson <Neale.Ferguson@SoftwareAG-USA.com> via Richard Levitte]
+) Add the configuration target debug-linux-ppro.
Make 'openssl rsa' use the general key loading routines
implemented in apps.c, and make those routines able to
handle the key format FORMAT_NETSCAPE and the variant
FORMAT_IISSGC.
[Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
*) Fix a crashbug and a logic bug in hwcrhk_load_pubkey().
[Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
+) Add -keyform to rsautl, and document -engine.
[Richard Levitte, inspired by Toomas Kiisk <vix@cyber.ee>]
+) Change BIO_new_file (crypto/bio/bss_file.c) to use new
BIO_R_NO_SUCH_FILE error code rather than the generic
ERR_R_SYS_LIB error code if fopen() fails with ENOENT.
[Ben Laurie]
+) Add new functions
ERR_peek_last_error
