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
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.
The constants below are defined by this extension, and
will only be available when the extension has either
been compiled into PHP or dynamically loaded at runtime.
Here is a list of hashes which are currently supported by mhash. If a
hash is not listed here, but is listed by mhash as supported, you can
safely assume that this documentation is outdated.
