These functions are intended to work with » mhash. Mhash can be used to create checksums, message digests, message authentication codes, and more.
This is an interface to the mhash library. Mhash supports a wide
variety of hash algorithms such as MD5, SHA1, GOST, and many
others. For a complete list of supported hashes, refer to the
constants page. The general rule is that you can access
the hash algorithm from PHP with MHASH_hashname. For example, to
access TIGER you use the PHP constant MHASH_TIGER.
