HMAC SHA-1 to Match RFC 2022 Test Vectors

See more Encryption Examples

Demonstrates using Chilkat in _LANGUAGE_ to computer HMAC SHA-1 message authentication codes to match the test vectors given by RFC 2202. 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 = 'sha-1';
$crypt->MacAlgorithm = 'hmac';

// Set the HMAC key:
$crypt->SetMacKeyEncoded('0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b0b','hex');
$mac = $crypt->macStringENC('Hi There');
print $mac . "\n";

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