(synopsis "Fast hashing in pure Go of BLAKE2b with SIMD instructions")
(description "This package was initially based on the pure go BLAKE2b
implementation of Dmitry Chestnykh and merged with the (cgo dependent) AVX
optimized BLAKE2 implementation (which in turn is based on the official
implementation. It does so by using Go's Assembler for amd64 architectures
with a golang only fallback for other architectures.
In addition to AVX there is also support for AVX2 as well as SSE. Best
performance is obtained with AVX2 which gives roughly a 4X performance
increase approaching hashing speeds of 1GB/sec on a single core.")
