This is my java implementation of the BLAKE-512 cryptographic hash function (version 1.3).

BLAKE was created by Jean-Philippe Aumasson, Luca Henzen, Willi Meier, and Raphael C.-W. Phan. It is one of the finalists for the sha3 hash.

The specifications can be found here: http://www.131002.net/blake/

Wikipedia article: http://en.wikipedia.org/wiki/BLAKE_%28hash_function%29

For a simple and easy to understand implementation of blake please have a look at revision 260b23fa13b1. later implementations contain a step by step optimized code. Revisions before 260b23fa13b1 should not be used.
