Fast strong hash functions: SipHash/HighwayHash (library)

Highwayhash provides three 'strong' (well-distributed and unpredictable) hash functions: a faster version of SipHash, a data-parallel variant of SipHash using tree hashing, and an even faster algorithm called HighwayHash.

SipHash is a fast but 'cryptographically strong' pseudo-random function by Aumasson and Bernstein [https://www.131002.net/siphash/siphash.pdf].

SipTreeHash slices inputs into 8-byte packets and computes their SipHash in parallel, which is faster when processing at least 96 bytes.

HighwayHash is a new way of mixing inputs which may inspire new cryptographically strong hashes. Large inputs are processed at a rate of 0.3 cycles per byte, and latency remains low even for small inputs. HighwayHash is faster than SipHash for all input sizes, with about 3.8 times higher throughput at 1 KiB.

This package ships the shared object.
