These functions are intended to work with mhash.
This is an interface to the mhash library. mhash supports a wide variety of hash algorithms such as MD5, SHA1, GOST, and many others.
To use it, download the mhash distribution from its web site and follow the included installation instructions. You need to compile PHP with the --with-mhash parameter to enable this extension.
mhash can be used to create checksums, message digests, and more.
Example 1. Compute the SHA1 key and print it out as hex <?php
$input = "Let us meet at 9 o' clock at the secret place.";
$hash = mhash(MHASH_SHA1, $input);
print "The hash is ".bin2hex($hash)."\n";
?>

The hash is d3b85d710d8f6e4e5efd4d5e67d041f9cecedafe
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 HAVAL you use the PHP constant
MHASH_HAVAL.
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 If a hash is not listed here, but is listed by mhash as supported, you can safely assume that this documentation is outdated.
MHASH_MD5
MHASH_SHA1
MHASH_HAVAL
MHASH_RIPEMD160
MHASH_RIPEMD128
MHASH_SNEFRU
MHASH_TIGER
MHASH_GOST
MHASH_CRC32
MHASH_CRC32B
