BLAKE2b-SIMD

Pure Go implementation of BLAKE2b using SIMD optimizations.

Introduction

This package is based on the pure go BLAKE2b implementation of Dmitry Chestnykh and merges it with the (cgo dependent) SSE optimized BLAKE2 implementation (which in turn is based on official implementation. It does so by using Go's Assembler for amd64 architectures with a fallback for other architectures.

It gives roughly a 3x performance improvement over the non-optimized go version.
