Mhash Functions

소개

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.

Note: This extension has been moved to the » PECL repository and is no longer bundled with PHP as of PHP 5.3.0. This extension is obsoleted by Hash.

요구 조건

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

설치

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

  • MHASH_HAVAL128
  • MHASH_HAVAL160
  • MHASH_HAVAL192
  • MHASH_HAVAL256
  • MHASH_MD4
  • MHASH_MD5
  • MHASH_RIPEMD160
  • MHASH_SHA1
  • MHASH_SHA256

예제

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";
$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
