Add a second template param to SecureVector which specifies the initial
length.
Change all callers to be SecureVector instead of SecureBuffer.
This can go away in C++0x, once compilers implement N2712 ("Non-static
data member initializers"), and we can just write code as
SecureVector<byte> P{18};
instead

bswap.h); too many external apps rely on loadstor.h existing.
Define 64-bit generic bswap in terms of 32-bit bswap, since it's
not much slower if 32-bit is also generic, and much faster if
it's not. This may be quite helpful on 32-bit x86 in particular.
Change formulation of generic 32-bit bswap. It may be faster or
slower depending on the CPU, especially the latency and throuput
of rotate instructions, but should be faster on an ideally
superscalar processor with rotate instructions (ie, what I expect
future CPUs to look more like).

Fixes for the amalgamation generator for internal headers.
Remove BOTAN_DLL exporting macros from all internal-only headers;
the classes/functions there don't need to be exported, and
avoiding the PIC/GOT indirection can be a big win.
Add missing BOTAN_DLLs where necessary, mostly gfpmath and cvc
For GCC, use -fvisibility=hidden and set BOTAN_DLL to the
visibility __attribute__ to export those classes/functions.

Pretty much useless and unused, except for listing the module names in
build.h and the short versions totally suffice for that.

just too fragile and not that useful. Something like Java's checked exceptions
might be nice, but simply killing the process entirely if an unexpected
exception is thrown is not exactly useful for something trying to be robust.

enc/dec functions it replaces, these are public interfaces.
Add the first bits of a SSE2 implementation of Serpent. Currently incomplete.

decryption. Currently only used for counter mode. Doesn't offer much
advantage as-is (though might help slightly, in terms of cache effects),
but allows for SIMD implementations to process multiple blocks in parallel
when possible. Particularly thinking here of Serpent; TEA/XTEA also seem
promising in this sense, as is Threefish once that is implemented as a
standalone block cipher.

In addition to the GOST 34.11 test parameters (used in Crypto++ among other
things), the GOST 34.11 CryptoPro parameters (used in implementations of the
GOST hash function) are now supported.

can be done directly, so there is no need to copy the key several times
for the key schedule (since the GOST 'key schedule' is very simple and the
access pattern can now be directly inserted into the code). Looks to be
about 10% faster on my Core2, as well.

up during the Fedora submission review, that each source file include some
text about the license. One handy Perl script later and each file now has
the line
Distributed under the terms of the Botan license
after the copyright notices.
While I was in there modifying every file anyway, I also stripped out the
remainder of the block comments (lots of astericks before and after the
text); this is stylistic thing I picked up when I was first learning C++
but in retrospect it is not a good style as the structure makes it harder
to modify comments (with the result that comments become fewer, shorter and
are less likely to be updated, which are not good things).

GostR3411_94_TestParamSet, this is compatible with the implementations in
Crypto++ and OpenSSL. This is not backwards compatible, though once the
implementation supports multiple param sets (which is required, unfortunately,
for compatability with various standards by CryptoCom, who have defined not
one but at least 4 (!!!) different sboxes to use with GOST), I may offer
Botan's previous sbox set as an option.
Since adding the GOST hash function (34.11) and signing algorithm (34.10)
are on the long term agenda (request by Rickard Bondesson, as the Russian
authorities want to use their local standards for their DNSSEC use), I
renamed the block cipher class (which had been just 'GOST') to GOST_28147_89
to minimize future name clashes.
