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 of siphash.highwayhash64: A new hash that mixes the inputs using AVX2 instructions.
It is about 5 times faster than siphash. 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.
