*) Bug fix for BN_div_recp() for numerators with an even number of
bits.
[Ulf Möller]
*) More tests in bntest.c, and changed test_bn output.
[Ulf Möller]
*) ./config recognizes MacOS X now.
[Andy Polyakov]
*) Bug fix for BN_div() when the first words of num and divsor are
equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
[Ulf Möller]
*) Add support for various broken PKCS#8 formats, and command line
options to produce them.
[Steve Henson]
*) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
get temporary BIGNUMs from a BN_CTX.
[Ulf Möller]
*) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
for p == 0.
[Ulf Möller]
*) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
include a #define from the old name to the new. The original intent
was that statically linked binaries could for example just call
SSLeay_add_all_ciphers() to just add ciphers to the table and not
link with digests. This never worked becayse SSLeay_add_all_digests()
and SSLeay_add_all_ciphers() were in the same source file so calling
one would link with the other. They are now in separate source files.
[Steve Henson]
*) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
[Steve Henson]
*) Use a less unusual form of the Miller-Rabin primality test (it used
a binary algorithm for exponentiation integrated into the Miller-Rabin
loop, our standard modexp algorithms are faster).
[Bodo Moeller]
*) Support for the EBCDIC character set completed.
*) Source code cleanups: use const where appropriate, eliminate casts,
use void * instead of char * in lhash.
[Ulf Möller]
*) Bugfix: ssl3_send_server_key_exchange was not restartable
(the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
this the server could overwrite ephemeral keys that the client
has already seen).
[Bodo Moeller]
*) Turn DSA_is_prime into a macro that calls BN_is_prime,
using 50 iterations of the Rabin-Miller test.
DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
iterations of the Rabin-Miller test as required by the appendix
to FIPS PUB 186[-1]) instead of DSA_is_prime.
As BN_is_prime_fasttest includes trial division, DSA parameter
generation becomes much faster.
This implies a change for the callback functions in DSA_is_prime
and DSA_generate_parameters: The callback function is called once
for each positive witness in the Rabin-Miller test, not just
occasionally in the inner loop; and the parameters to the
callback function now provide an iteration count for the outer
loop rather than for the current invocation of the inner loop.
DSA_generate_parameters additionally can call the callback
function with an 'iteration count' of -1, meaning that a
candidate has passed the trial division test (when q is generated
from an application-provided seed, trial division is skipped).
*) New function BN_is_prime_fasttest that optionally does trial
division before starting the Rabin-Miller test and has
an additional BN_CTX * argument (whereas BN_is_prime always
has to allocate at least one BN_CTX).
'callback(1, -1, cb_arg)' is called when a number has passed the
trial division stage.
[Bodo Moeller]
*) Fix for bug in CRL encoding. The validity dates weren't being handled
as ASN1_TIME.
[Steve Henson]
*) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
[Steve Henson]
*) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
bignum version of BN_from_montgomery() with the working code from
SSLeay 0.9.0 (the word based version is faster anyway), and clean up
the comments.
[Ulf Möller]
*) Avoid a race condition in s2_clnt.c (function get_server_hello) that
made it impossible to use the same SSL_SESSION data structure in
SSL2 clients in multiple threads.
[Bodo Moeller]
*) The return value of RAND_load_file() no longer counts bytes obtained
by stat(). RAND_load_file(..., -1) is new and uses the complete file
to seed the PRNG (previously an explicit byte count was required).
[Ulf Möller, Bodo Möller]
*) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
used (char *) instead of (void *) and had casts all over the place.
[Steve Henson]
*) Make BN_generate_prime() return NULL on error if ret!=NULL.
[Ulf Möller]
*) Retain source code compatibility for BN_prime_checks macro:
BN_is_prime(..., BN_prime_checks, ...) now uses
BN_prime_checks_for_size to determine the appropriate number of
Rabin-Miller iterations.
[Ulf Möller]
*) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
DH_CHECK_P_NOT_SAFE_PRIME.
(Check if this is true? OpenPGP calls them "strong".)
[Ulf Möller]
*) Merge the functionality of "dh" and "gendh" programs into a new program
"dhparam". The old programs are retained for now but will handle DH keys
(instead of parameters) in future.
[Steve Henson]
*) Make the ciphers, s_server and s_client programs check the return values
when a new cipher list is set.
[Steve Henson]
*) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
ciphers. Before when the 56bit ciphers were enabled the sorting was
wrong.
The syntax for the cipher sorting has been extended to support sorting by
cipher-strength (using the strength_bits hard coded in the tables).
The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
Fix a bug in the cipher-command parser: when supplying a cipher command
string with an "undefined" symbol (neither command nor alphanumeric
[A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
an error is flagged.
Due to the strength-sorting extension, the code of the
ssl_create_cipher_list() function was completely rearranged. I hope that
the readability was also increased :-)
[Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
*) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
for the first serial number and places 2 in the serial number file. This
avoids problems when the root CA is created with serial number zero and
the first user certificate has the same issuer name and serial number
as the root CA.
[Steve Henson]
*) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
the new code. Add documentation for this stuff.
[Steve Henson]
*) Changes to X509_ATTRIBUTE utilities. These have been renamed from
X509_*() to X509at_*() on the grounds that they don't handle X509
structures and behave in an analagous way to the X509v3 functions:
they shouldn't be called directly but wrapper functions should be used
instead.
So we also now have some wrapper functions that call the X509at functions
when passed certificate requests. (TO DO: similar things can be done with
PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
things. Some of these need some d2i or i2d and print functionality
because they handle more complex structures.)
[Steve Henson]
*) Add missing #ifndefs that caused missing symbols when building libssl
as a shared library without RSA. Use #ifndef NO_SSL2 instead of
NO_RSA in ssl/s2*.c.
[Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf Möller]
*) Precautions against using the PRNG uninitialized: RAND_bytes() now
has a return value which indicates the quality of the random data
(1 = ok, 0 = not seeded). Also an error is recorded on the thread's
error queue. New function RAND_pseudo_bytes() generates output that is
guaranteed to be unique but not unpredictable.
[Ulf Möller]
*) Do more iterations of Rabin-Miller probable prime test (specifically,
3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
