BLAKE2 family of hash functions

The BLAKE2 family of hash functions is an improved version of the SHA-3 finalist BLAKE.

BLAKE2b is optimized for 64-bit platforms and produces up to 64 bytes of output; BLAKE2s is optimized for 32-bit platforms and produces up to 32 bytes of output.

BLAKE2bp and BLAKE2sp are parallel versions of BLAKE2b and BLAKE2s designed for increased performance on multicore and large-vector SIMD processors.

libb2 provides a portable implementation of BLAKE2, optimized implementations for IA-32 and AMD64 processors, and an interface layer that automatically selects the best implementation for the processor it is run on.
