* Some modules using asm were not marked with 'load_on asm_ok'; fixlloyd2009-07-071-1/+1

* CPU-specific engines are now only loaded if something depends on them,lloyd2009-07-071-0/+1
| | | | | | | | | | | | and all CPU-specific implementations now depend on the appropriate engine module. The most common problem before with this was that the SSE2 module was built, but the sole SSE2 code (SHA-1) was not (for instance, on an i686). This would cause a compile warning about the unused request object. Preventing unused engines from being built will also (very slightly) speed up the lookup process on most system.

* Partially unroll the round structure, enough so that the subkey accesseslloyd2009-03-312-36/+40
| | | | | | | 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.
* Thomas Moschny passed along a request from the Fedora packagers which camelloyd2009-03-3062-737/+861
| | | | | | | | | | | | | | | 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).

* GOST was using a completely non-standard set of sboxes. Change it to uselloyd2009-03-277-311/+152
| | | | | | | | | | | | | | | 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.
