highwayhash | Fast strong hash functions : SipHash/HighwayHash | Hashing library

highwayhash is a C++ library typically used in Security, Hashing applications. highwayhash has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Hash functions are widely used, so it is desirable to increase their speed and security. This package provides two 'strong' (well-distributed and unpredictable) hash functions: a faster version of SipHash, and an even faster algorithm we call HighwayHash. SipHash is a fast but 'cryptographically strong' pseudo-random function by Aumasson and Bernstein [HighwayHash is a new way of mixing inputs which may inspire new cryptographically strong hashes. Large inputs are processed at a rate of 0.24 cycles per byte, and latency remains low even for small inputs. HighwayHash is faster than SipHash for all input sizes, with 5 times higher throughput at 1 KiB. We discuss design choices and provide statistical analysis and preliminary cryptanalysis in
