| * Conver the rest of the hash functions to use the array-based load instructions.lloyd2009-11-035-40/+41
| | | | | | | | | | | | | | I'm not totally happy with this - in particular in all cases the size is a compile time constant - it would be nice to make use of this via tempalate metaprogramming. Also for matching endian loads, a straight memcpy would do the work, which would probably be even faster.

| | | | | | | | | | | | | | | | change some of the hash functions to use it as low hanging fruit. Probably could use further optimization (just unrolls x4 currently), but merely having it as syntax is good as it allows optimizing many functions at once (eg using SSE2 to do 4-way byteswaps).

Also hide TLS_PRF::P_hash in an anonymous namespace instead of making it a private static function. I don't think this will affect binary compat, since it was statically linked.

* CPU-specific engines are now only loaded if something depends on them,lloyd2009-07-075-0/+5
| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | Add a comment that the limitation of the personalization string being a maximum of 64 characters is due to the implementation and not the specification (but it makes it easy to implement, and in this particular case 64 characters is probably fine). Add some tests for the personalization option, generated by the Skein reference implementation. Disable stripping whitespace in checks/misc.cpp:strip - it strips the personalization tag, which breaks the test, and isn't needed otherwise because the test files are well-formed.

| | | | | | | | | | | | | | | 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).
