p5-Digest-Haval256

Perl extension for Haval256 hash algorithm

Haval is a variable-length, variable-round one-way hash function designed by Yuliang Zheng, Josef Pieprzyk, and Jennifer Seberry. The number of rounds can be 3, 4, or 5, while the hash length can be 128, 160, 192, 224, or 256 bits. Thus, there are a total of 15 different outputs. For better security, however, this module implements the 5-round, 256-bit output.
