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.

Notă: Această extensie a fost transferată în repozitoriul » PECL şi nu mai este furnizată împreună cu PHP începând cu versiunea 5.3.0. This extension is obsoleted by Hash.

Necesităţi

Exemple

Example#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"
