(PHP Extension) HMAC SHA-1 to Match RFC 2022 Test Vectors

Demonstrates using Chilkat in PHP Extension to computer HMAC SHA-1 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('sha-1');

// Set the HMAC key:
$crypt->SetHmacKeyEncoded('0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b','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";
