The BLAKE2 Cryptographic Hash and Message Authentication Code

Overview

RFC 7693, “The BLAKE2 Cryptographic Hash and Message Authentication Code”, is an Informational document published in November 2015 by M-J. Saarinen, J-P. Aumasson. The canonical text is published by the RFC Editor.

Abstract

This document describes the cryptographic hash function BLAKE2 and makes the algorithm specification and C source code conveniently available to the Internet community. BLAKE2 comes in two main flavors: BLAKE2b is optimized for 64-bit platforms and BLAKE2s for smaller architectures. BLAKE2 can be directly keyed, making it functionally equivalent to a Message Authentication Code (MAC).
