BLAKE2 RIOT package

BLAKE2 is a cryptographic hash function specified in RFC 7693. It claims to be faster than MD5, SHA-1, SHA-2, and SHA-3, yet at least as secure as the latest standard SHA-3.

BLAKE2 comes in two flavors:

BLAKE2b (or just BLAKE2) is optimized for 64-bit platforms—including NEON-enabled ARMs—and produces digests of any size between 1 and 64 bytes
BLAKE2s is optimized for 8- to 32-bit platforms and produces digests of any size between 1 and 32 bytes

For more information, see the BLAKE2 website.

Usage

Add it as a package in your application's Makefile:

USEPKG += libb2

Include the BLAKE2 header in your code:

#include "blake2.h"
