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

* Split base.h into block_cipher.h and stream_cipher.hlloyd2008-11-081-0/+11
| | | | | | It turned out many files were including base.h merely to get other includes (like types.h, secmem.h, and exceptn.h). Those have been changed to directly include the files containing the declarations that code needs.

* Derive x86, x86-64, and SSE2 implementations of SHA-1 directly from SHA_160lloyd2008-09-2911-106/+27

* 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).

* Make mdx_hash also a module, which most of the hash functions depend on.lloyd2008-09-2816-0/+612
| | | | | | Correct the configure program so modules are not autoloaded if their dependences are not available. (Eg, --no-module=mdx_hash will disable MD4, MD5, SHA-1, etc rather than cause a compliation failure)
