HMAC-MD5 Authentication

The following code samples provide examples for creating a HMAC-MD5 encryption algorithms in JavaScript and Perl for Forte's SOAP web services and Secure Web Pay application, specifically the pg_ts_hash (SWP) and TSHash (SOAP web services) parameters. NOTE: The JavaScript code should only be used internally or on a secure intranet as the Secret Key is viewable to anyone who views the HTML source code. 

Perl

#!/usr/bin/perl

use Digest::HMAC_MD5 qw(hmac_md5_hex);

# generate hex hash of message with secret key
my $digest = hmac_md5_hex("MESSAGE_TEXT","SECRET_KEY");

print $digest;

JavaScript

<script type="text/javascript" src="http://crypto-js.googlecode.com/files/2.2.0-crypto-md5.js"></script>
<script type="text/javascript" src="http://crypto-js.googlecode.com/files/2.2.0-hmac-min.js"></script>
<script type="text/javascript">
     // Generate hex hash of message with secret key
     var hmac = Crypto.HMAC(Crypto.MD5, "MESSAGE", "SECRET_KEY");
</script>
