Javascript HMAC SHA256

Run the code online with this jsfiddle. Dependent upon an open source js library calledhttp://code.google.com/p/crypto-js/.

<script src="http://crypto-js.googlecode.com/svn/tags/3.0.2/build/rollups/hmac-sha256.js"></script>
<script src="http://crypto-js.googlecode.com/svn/tags/3.0.2/build/components/enc-base64-min.js"></script>

<script>
  var hash = CryptoJS.HmacSHA256("Message", "secret");
  var hashInBase64 = CryptoJS.enc.Base64.stringify(hash);
  document.write(hashInBase64);
</script>

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

Dependent on Apache Commons Codec to encode in base64.

import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import org.apache.commons.codec.binary.Base64;

public class ApiSecurityExample {
    
    
  public static void main(String[] args) {
    
    
    try {
    
    
     String secret = "secret";
     String message = "Message";

     Mac sha256_HMAC = Mac.getInstance("HmacSHA256");
     SecretKeySpec secret_key = new SecretKeySpec(secret.getBytes(), "HmacSHA256");
     sha256_HMAC.init(secret_key);

     String hash = Base64.encodeBase64String(sha256_HMAC.doFinal(message.getBytes()));
     System.out.println(hash);
    }
    catch (Exception e){
    
    
     System.out.println("Error");
    }
   }
}
