## The BLAKE2b hash algorithm

BLAKE2b is a fast cryptographic hash function described in [RFC 7963](https://tools.ietf.org/html/rfc7693).

BLAKE2b can be directly keyed, making it functionally equivalent to a Message Authentication Code (MAC).

### Recommendation 

This BLAKE2b implementation was submitted to the golang x/crypto repo.

I recommend to use the official [x/crypto/blake2b](https://godoc.org/golang.org/x/crypto/blake2b) package if possible.

### Installation

Install in your GOPATH: `go get -u github.com/aead/blake2b`
