Changes between 0.9.6 and 0.9.7 [xx XXX 2000]
*) New function BN_swap.
[Bodo Moeller]
*) Use BN_nnmod instead of BN_mod in crypto/bn/bn_exp.c so that
the exponentiation functions are more likely to produce reasonable
results on negative inputs.
[Bodo Moeller]
*) Change BN_mod_mul so that the result is always non-negative.
Previously, it could be negative if one of the factors was negative;
I don't think anyone really wanted that behaviour.
[Bodo Moeller]
*) Move BN_mod_... functions into new file crypto/bn/bn_mod.c
(except for exponentation, which stays in crypto/bn/bn_exp.c,
and BN_mod_mul_reciprocal, which stays in crypto/bn/bn_recp.c)
and add new functions:
BN_nnmod
BN_mod_sqr
BN_mod_add
BN_mod_sub
These functions always generate non-negative results.
BN_nnmod otherwise is like BN_mod (if BN_mod computes a remainder r
such that |m| < r < 0, BN_nnmod will output rem + |m| instead).
[Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller]
*) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there
was actually never needed) and in BN_mul(). The removal in BN_mul()
required a small change in bn_mul_part_recursive() and the addition
of the static functions bn_cmp_part_words(), bn_sub_part_words()
and bn_add_part_words() which do the same thing as bn_cmp_words(),
bn_sub_words() and bn_add_words() except they take arrays with
differing sizes.
[Richard Levitte]
*) In 'openssl passwd', verify passwords read from the terminal
unless the '-salt' option is used (which usually means that
verification would just waste user's time since the resulting
hash is going to be compared with some given password hash)
or the new '-noverify' option is used.
This is an incompatible change, but it does not affect
non-interactive use of 'openssl passwd' (passwords on the command
line, '-stdin' option, '-in ...' option) and thus should not
cause any problems.
[Bodo Moeller]
*) Remove all references to RSAref, since there's no more need for it.
[Richard Levitte]
*) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
The previous value, 12, was not always sufficient for BN_mod_exp().
[Bodo Moeller]
*) Make DSO load along a path given through an environment variable
(SHLIB_PATH) with shl_load().
[Richard Levitte]
*) Constify the ENGINE code as a result of BIGNUM constification.
Also constify the RSA code and most things related to it. In a
few places, most notable in the depth of the ASN.1 code, ugly
casts back to non-const were required (to be solved at a later
time)
[Richard Levitte]
*) Make it so the openssl application has all engines loaded by default.
[Richard Levitte]
*) Constify the BIGNUM routines a little more.
[Richard Levitte]
*) Make sure that shared libraries get the internal name engine with
the full version number and not just 0. This should mark the
shared libraries as not backward compatible. Of course, this should
be changed again when we can guarantee backward binary compatibility.
[Richard Levitte]
*) Add the following functions:
ENGINE_load_cswift()
ENGINE_load_chil()
ENGINE_load_atalla()
ENGINE_load_nuron()
ENGINE_load_builtin_engines()
That way, an application can itself choose if external engines that
are built-in in OpenSSL shall ever be used or not. The benefit is
that applications won't have to be linked with libdl or other dso
libraries unless it's really needed.
Changed 'openssl engine' to load all engines on demand.
Changed the engine header files to avoid the duplication of some
declarations (they differed!).
[Richard Levitte]
*) 'openssl engine' can now list capabilities.
[Richard Levitte]
*) Better error reporting in 'openssl engine'.
[Richard Levitte]
*) Never call load_dh_param(NULL) in s_server.
[Bodo Moeller]
*) Add engine application. It can currently list engines by name and
identity, and test if they are actually available.
[Richard Levitte]
*) Add support for shared libraries under Irix.
[Albert Chin-A-Young <china@thewrittenword.com>]
*) Improve RPM specification file by forcing symbolic linking and making
sure the installed documentation is also owned by root.root.
[Damien Miller <djm@mindrot.org>]
*) Add configuration option to build on Linux on both big-endian and
little-endian MIPS.
[Ralf Baechle <ralf@uni-koblenz.de>]
*) Give the OpenSSL applications more possibilities to make use of
keys (public as well as private) handled by engines.
[Richard Levitte]
*) Add OCSP code that comes from CertCo.
[Richard Levitte]
[Richard Levitte]
*) Added untested support for Nuron crypto accelerator.
[Ben Laurie]
*) Add support for external cryptographic devices. This code was
previously distributed separately as the "engine" branch.
[Geoff Thorpe, Richard Levitte]
*) Rework the filename-translation in the DSO code. It is now possible to
have far greater control over how a "name" is turned into a filename
depending on the operating environment and any oddities about the
different shared library filenames on each system.
[Geoff Thorpe]
*) Support threads on FreeBSD-elf in Configure.
[Richard Levitte]
*) Add the possibility to create shared libraries on HP-UX
[Richard Levitte]
*) Fix for SHA1 assembly problem with MASM: it produces
warnings about corrupt line number information when assembling
with debugging information. This is caused by the overlapping
of two sections.
[Bernd Matthes <mainbug@celocom.de>, Steve Henson]
*) NCONF changes.
NCONF_get_number() has no error checking at all. As a replacement,
NCONF_get_number_e() is defined (_e for "error checking") and is
promoted strongly. The old NCONF_get_number is kept around for
binary backward compatibility.
Make it possible for methods to load from something other than a BIO,
by providing a function pointer that is given a name instead of a BIO.
For example, this could be used to load configuration data from an
LDAP server.
[Richard Levitte]
*) Fix typo in get_cert_by_subject() in by_dir.c
[Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
*) Rework the system to generate shared libraries:
- Make note of the expected extension for the shared libraries and
if there is a need for symbolic links from for example libcrypto.so.0
to libcrypto.so.0.9.7. There is extended info in Configure for
that.
- Make as few rebuilds of the shared libraries as possible.
- Still avoid linking the OpenSSL programs with the shared libraries.
- When installing, install the shared libraries separately from the
static ones.
[Richard Levitte]
*) Fix for non blocking accept BIOs. Added new I/O special reason
BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs
with non blocking I/O was not possible because no retry code was
implemented. Also added new SSL code SSL_WANT_ACCEPT to cover
this case.
[Steve Henson]
*) Added the beginnings of Rijndael support.
[Ben Laurie]
*) Fix for bug in DirectoryString mask setting. Add support for
X509_NAME_print_ex() in 'req' and X509_print_ex() function
