HMAC with SHA256

Demonstrates how to compute a HMAC SHA256 keyed-hash message authentication code. PHP ActiveX

<?php

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

$crypt = new COM("Chilkat.Crypt2");

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

// Set the hash algorithm:
// Choices are: md5, sha-1, sha256, sha384, sha512, md2, haval
$crypt->HashAlgorithm = 'sha256';
$crypt->MacAlgorithm = 'hmac';

// Set the HMAC key:
$crypt->SetMacKeyEncoded('The_API_Secret','ascii');
$mac = $crypt->macStringENC('The quick brown fox jumps over the lazy dog');
print $mac . "\n";
