The BLAKE2 Cryptographic Hash and Message Authentication Code (MAC)

M-J. Saarinen, J.-P. Aumasson

Open publisher page 38 citations

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).
