"xxHash is an extremely fast non-cryptographic hash algorithm. It works
at speeds close to RAM limits, and comes in both 32- and 64-bit flavours.
The code is highly portable, and hashes of the same length are identical on all
platforms (both big and little endian).")

(description
"libb2 is a portable implementation of the BLAKE2 family of cryptographic
hash functions. It includes optimised implementations for IA-32 and AMD64
processors, and an interface layer that automatically selects the best
implementation for the processor it is run on.
@dfn{BLAKE2} (RFC 7693) is a family of high-speed cryptographic hash functions
that are faster than MD5, SHA-1, SHA-2, and SHA-3, yet are at least as secure
as the latest standard, SHA-3. It is an improved version of the SHA-3 finalist
BLAKE.")
