LX. Mhash Functions

Introducere

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.

Necesităţi

To use it, download the mhash distribution from its web site and follow the included installation instructions.

Instalare

You need to compile PHP with the --with-mhash[=DIR] parameter to enable this extension. DIR is the mhash install directory.

Constante predefinite

Aceste constante sunt definite de această extensie şi vor fi disponibile doar cînd extensia a fost fie compilată odată la instalarea PHP fie dacă extensia este încărcată dinamic la rulare.

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 If a hash is not listed here, but is listed by mhash as supported, you can safely assume that this documentation is outdated.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_HAVAL256
MHASH_HAVAL192
MHASH_HAVAL160
MHASH_HAVAL128
MHASH_RIPEMD160
MHASH_GOST
MHASH_TIGER
MHASH_CRC32
MHASH_CRC32B

Exemple

Exemplu 1. Compute the MD5 digest and hmac and print it out as hex


<?php
$input = "what do ya want for nothing?";
$hash = mhash(MHASH_MD5, $input);
echo "The hash is " . bin2hex($hash) . "<br />\n";
$hash = mhash(MHASH_MD5, $input, "Jefe");
echo "The hmac is " . bin2hex($hash) . "<br />\n";
?>

This will produce:

The hash is d03cb659cbf9192dcd066272249f8412 
The hmac is 750c783e6ab0b503eaa86e310a5db738
