Raw Blame History

// sha.cpp - modified by Wei Dai from Steve Reid's public domain sha1.c
// Steve Reid implemented SHA-1. Wei Dai implemented SHA-2. Jeffrey Walton
// implemented Intel SHA extensions based on Intel articles and code by
// Sean Gulley. Jeffrey Walton implemented ARM SHA based on ARM code and
// code from Johannes Schneiders, Skip Hovsmith and Barry O'Rourke.
// All code is in the public domain.
// In August 2017 JW reworked the internals to align all the implementations.
// Formerly all hashes were software based, IterHashBase handled endian conversions,
// and IterHashBase dispatched a single to block SHA{N}::Transform. SHA{N}::Transform
// then performed the single block hashing. It was repeated for multiple blocks.
//
// The rework added SHA{N}::HashMultipleBlocks (class) and SHA{N}_HashMultipleBlocks
// (free standing). There are also hardware accelerated variations. Callers enter
// SHA{N}::HashMultipleBlocks (class), and the function calls SHA{N}_HashMultipleBlocks
// (free standing) or SHA{N}_HashBlock (free standing) as a fallback.
//
// An added wrinkle is hardware is little endian, C++ is big endian, and callers use
// big endian, so SHA{N}_HashMultipleBlock accepts a ByteOrder for the incoming data
// arrangement. Hardware based SHA{N}_HashMultipleBlock can often perform the endian
// swap much easier by setting an EPI mask. Endian swap incurs no penalty on Intel SHA,
// and 4-instruction penalty on ARM SHA. Under C++ the full software based swap penalty
// is incurred due to use of ReverseBytes().
//
// The rework also removed the hacked-in pointers to implementations.
// use "cl /EP /P /DCRYPTOPP_GENERATE_X64_MASM sha.cpp" to generate MASM code
