How to create Base64 hashes using HMAC SHA256?

PHP HMAC SHA256 PHP has built in methods for hash_hmac(PHP 5) and base64_encode(PHP 4, PHP 5) resulting in no outside dependencies. Say what you want about PHP but they have the cleanest code for this example. $s = hash_hmac(‘sha256’, ‘Message’, ‘secret’, true);echo base64_encode($s); Java HMAC SHA256
