(PHP Extension) HMAC MD5 to Match RFC 2022 Test Vectors

Demonstrates using Chilkat in PHP Extension to computer HMAC MD5 message authentication codes to match the test vectors given by RFC 2202.

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

$crypt = new CkCrypt2();

// The output will be Hex, so set the EncodingMode:
$crypt->put_EncodingMode('hex');

// Set the hash algorithm:
// Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
$crypt->put_HashAlgorithm('md5');

// Set the HMAC key:
$crypt->SetHmacKeyEncoded('0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b','hex');
$mac = $crypt->hmacStringENC('Hi There');
print $mac . "\n";

$crypt->SetHmacKeyEncoded('Jefe','ansi');
$mac = $crypt->hmacStringENC('what do ya want for nothing?');
print $mac . "\n";
