Internal Program Version: Mhash  0.9.9.9

Mhash is a library that provides a uniform interface to a large
number of hash algorithms. These algorithms can be used to
compute checksums, message digests, and other signatures.
The HMAC support implements the basics for message authentication,
following RFC 2104. Mhash also provides several key-generation
algorithms, including those of OpenPGP (RFC 2440).
