I'm not usre where exactly the break occured, but it was probably due to the BASE+SIMD rewrite. Thanks to tesbayda for tracking it down.

Reworked SHA class internals to align all the implementations. Formerly all hashes were software based, IterHashBase handled endian conversions, IterHashBase repeatedly called the single block SHA{N}::Transform. The rework added SHA{N}::HashMultipleBlocks, and the SHA classes attempt to always use it.
Now SHA{N}::Transform calls into SHA{N}_HashMultipleBlocks, which is a free standing function. An added wrinkle is hardware wants little endian data and software presents big endian data, so HashMultipleBlocks accepts a ByteOrder for the incoming data. Hardware based SHA{N}_HashMultipleBlocks can often perform the endian swap much easier by setting an EPI mask so it was profitable to defer to hardware when available.
The rework also removed the hacked-in pointers to implementations. The class now looks more like AES, GCM, etc.

add DEFAULT_CHANNEL and AAD_CHANNEL,
fix macChannel for AuthenticatedEncryptionFilter
|
|
- added AuthenticatedSymmetricCipher interface class and Filter wrappers
- added CCM, GCM (with SSE2 assembly), CMAC, and SEED
- improved AES speed on x86 and x64
- removed WORD64_AVAILABLE; compiler 64-bit int support is now required
