Rust Bindings to AVX2-optimized SIP-like hash functions. This crate offers bindings to three hash functions implemented in C++ here:
siphash: A portable implementation of the SIP hash function, that is about 2 times faster than the reference implementation.siphash13: A faster but weaker variant ofsiphash.highwayhash64: A new hash that mixes the inputs using AVX2 instructions. It is about 5 times faster thansiphash. A preliminary cryptanalysis is given here.
For highwayhash64 there are three implementations: one using AVX2, another one
using SSE4.1 and a third one that is portable by not relying on specific
instruction sets. To profit from the faster implementations, make sure to enable
the instruction sets at compile time using RUSTFLAGS="-C target-cpu=native" or
similar.
The bindings are in an early state. They currently should work on Unix, but are
only tested on Linux. make and a C++ compiler are required to build the
underlying C++ library. A nightly Rust compiler is required.
