HMAC with SHA256

See more Encryption Examples

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

<?php

include("chilkat.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('sha256');
$crypt->put_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";
