* Move free standing function into anonymous namespaceJeffrey Walton2017-08-141-166/+230

* Fix bad SHA::Transform calculation (Issue 455)Jeffrey Walton2017-08-131-563/+598
| | | | | | | | 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.

* Fix endian-reversal and loading of MSG0-MSG3Jeffrey Walton2017-04-221-7/+1
| | | | | | Initially we performed a 32-bit word-size ByteReverse() on the entire 64-byte buffer being hashed. Then we performed another fix-up when loading each 16-byte portion of the buffer into the SSE2 registers for SHA processing. The [undesired] consequence was byte swapping and reversals happened twice. Worse, the call to ByteReverse() produced 16 bswaps instead of 1 call pshufb, so it was orders of magnitude slower than it needed to be. This check-in takes the sane approach to byte reversals and swapping. It performs it once when the message is loaded for SSE processing. The result is SHA1 calculations drop from about 3.0 cpb to about 2.5 cpb.
