These functions are intended to work with <ulink
url="&url.mhash;">mhash</ulink>. Mhash can be used to create checksums,
message digests, message authentication codes, and more.

<para>
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
documentation of mhash. 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.

To use it, download the mhash distribution from <ulink

installation instructions.
