DESCRIPTION: Mhash is a free library which provides a uniform interface to a large number of hash algorithms. Mhash is a free (under GNU Lesser GPL) library which 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. In the later versions some key generation algorithms, which use hash algorithms, have been added. The manpage for mhash is mhash.3.html. At the time of writing this, the library supports the algorithms: SHA1, SHA160, SHA192, SHA224, SHA384, SHA512, HAVAL128, HAVAL160, HAVAL192, HAVAL224, HAVAL256, RIPEMD128, RIPEMD256, RIPEMD320, MD4, MD5, TIGER, TIGER128, TIGER160, ALDER32, CRC32, CRC32b, WHIRLPOOL, GOST, SNEFRU128, SNEFRU256
