PHP扩展布莱克哈希

BLAKE Hash extension for PHP The BLAKE Hash is one of the five finalist algorithms that participates in the NIST SHA-3 competition. This hash functions is based on the HAIFA structure and the ChaCha core function. The algorithm was designed by Jean-Philippe Aumasson, Luca Henzen, Willi Meier and Raphael C.-W. Phan. There are four instances of the function, the first two, BLAKE224 and BLAKE256 work with 32-bit words and they have an output of 28 and 32 bytes respectively. The other two, BLAKE384 and BLAKE512 work with 64-bit words and they have an output of 48 and 64 bytes respectively. The algorithm has been designed to be secure and to have high performance (Even better than SHA-2). The code is based on the final round package sent. Examples ```
