_______________
*) Fix potential buffer overrun problem in BIO_printf().
[Ulf Möller, using public domain code by Patrick Powell; problem
pointed out by David Sacerdote <das33@cornell.edu>]
*) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
RAND_egd() and RAND_status(). In the command line application,
the EGD socket can be specified like a seed file using RANDFILE
or -rand.
[Ulf Möller]
*) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
Some CAs (e.g. Verisign) distribute certificates in this form.
[Steve Henson]
*) Remove the SSL_ALLOW_ADH compile option and set the default cipher
list to exclude them. This means that no special compilation option
is needed to use anonymous DH: it just needs to be included in the
cipher list.
[Steve Henson]
*) Change the EVP_MD_CTX_type macro so its meaning consistent with
EVP_MD_type. The old functionality is available in a new macro called
EVP_MD_md(). Change code that uses it and update docs.
[Steve Henson]
*) ..._ctrl functions now have corresponding ..._callback_ctrl functions
where the 'void *' argument is replaced by a function pointer argument.
Previously 'void *' was abused to point to functions, which works on
many platforms, but is not correct. As these functions are usually
called by macros defined in OpenSSL header files, most source code
should work without changes.
*) <openssl/opensslconf.h> (which is created by Configure) now contains
sections with information on -D... compiler switches used for
compiling the library so that applications can see them. To enable
one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
must be defined. E.g.,
#define OPENSSL_ALGORITHM_DEFINES
#include <openssl/opensslconf.h>
defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
*) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
record layer.
[Bodo Moeller]
*) Change the 'other' type in certificate aux info to a STACK_OF
X509_ALGOR. Although not an AlgorithmIdentifier as such it has
the required ASN1 format: arbitrary types determined by an OID.
[Steve Henson]
*) Add some PEM_write_X509_REQ_NEW() functions and a command line
argument to 'req'. This is not because the function is newer or
better than others it just uses the work 'NEW' in the certificate
request header lines. Some software needs this.
[Steve Henson]
*) Reorganise password command line arguments: now passwords can be
obtained from various sources. Delete the PEM_cb function and make
it the default behaviour: i.e. if the callback is NULL and the
usrdata argument is not NULL interpret it as a null terminated pass
phrase. If usrdata and the callback are NULL then the pass phrase
is prompted for as usual.
[Steve Henson]
*) Add support for the Compaq Atalla crypto accelerator. If it is installed,
the support is automatically enabled. The resulting binaries will
autodetect the card and use it if present.
[Ben Laurie and Compaq Inc.]
*) Work around for Netscape hang bug. This sends certificate request
and server done in one record. Since this is perfectly legal in the
SSL/TLS protocol it isn't a "bug" option and is on by default. See
the bugs/SSLv3 entry for more info.
[Steve Henson]
*) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
[Andy Polyakov]
*) Add -rand argument to smime and pkcs12 applications and read/write
of seed file.
[Steve Henson]
*) Add command line password options to the remaining applications.
[Steve Henson]
*) 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.
