Expand description
SHA-2 family from FIPS 180-4.
This module includes both the 32-bit and 64-bit SHA-2 lines:
Sha224,Sha256Sha384,Sha512Sha512_224,Sha512_256
The implementation keeps the two compression functions separate because the 32-bit and 64-bit schedules really are different algorithms at the round level, even though the high-level padding rules are shared.
