| | | | | | | | | Useful for tracking where the big balls of mud are. Fix dependencies in gost_3411 (depends on the gost block cipher), and the TLS PRF (depends on HMAC). 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.

* Thomas Moschny passed along a request from the Fedora packagers which camelloyd2009-03-3042-474/+556
| | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to have been so! Change MDx_HashFunction::hash to a new compress_n which hashes an arbitrary number of blocks. I had a thought this might reduce a bit of loop overhead but the results were far better than I anticipated. Speedup across the board of about 2%, and very noticable (+10%) increases for MD4 and Tiger (probably b/c both of those have so few instructions in each iteration of the compression function).

* Derive the x86 assembly implementations of MD4, MD5, and Serpent fromlloyd2008-09-297-66/+7
| | | | | | | | | | the normal Botan base classes. This required making data members of MD4, MD5, and Serpent protected rather than private, which is not very good style IMO. On the other hand it allows for removing a bit of duplicated code, and also has the nice effect that a pointer to a Serpent_IA32 can be used right as a Serpent object, which makes sense anyway since they implement the same algorithm. The C++ files in the *_ia32 modules are now simply hooks between the virtual function call runtime and the assembly code.
* Make asm implementations distinctly named objects, for instance MD5_IA32,lloyd2008-09-2921-144/+289
| | | | | | | | | | | | | | | | | | | rather than silently replacing the C++ versions. Instead they are silently replaced (currently, at least) at the lookup level: we switch off the set of feature macros set to choose the best implementation in the current build configuration. So you can have (and benchmark) MD5 and MD5_IA32 directly against each other in the same program with no hassles, but if you ask for "MD5", you'll get maybe an MD5 or maybe MD5_IA32. Also make the canonical asm names (which aren't guarded by C++ namespaces) of the form botan_<algo>_<arch>_<func> as in botan_sha160_ia32_compress, to avoid namespace collisions. This change has another bonus that it should in many cases be possible to derive the asm specializations directly from the original implementation, saving some code (and of course logically SHA_160_IA32 is a SHA_160, just one with a faster implementation of the compression function, so this seems reasonable anyway).
