Using CryptoJS for AES decryption

This tutorial is amazing, it runs through CryptoJS, but unfortunately doesn’t make clear the ┬ámost important point. This code demonstrates AES encryption and decryption:

var key = CryptoJS.lib.WordArray.random(16);
var iv = CryptoJS.lib.WordArray.random(16);
var encrypted = CryptoJS.AES.encrypt("Message", key.toString(), { iv: iv.toString() });
var decrypted = CryptoJS.AES.decrypt(encrypted.toString(), key.toString(), { iv: iv.toString() });

But if you can’t get the decrypted content at the end, you have to do this:


I’m sure this will save a lot of heartache.
