title: Node.js - Set padding in crypto module
body: <p>I've been looking over the docs for the <a href="http://nodejs.org/api/crypto.html" rel="noreferrer">crypto module</a> in Node, and I'm trying to figure out how to set the padding when doing symmetric encryption. I'm trying to use AES-128-ECB, with PKCS5 padding.</p>
  
  <p>I can't see anywhere that it allows you to specify padding. I would certainly hope this is possible to do using this library. How can I specify padding for symmetric encryption in the crypto module?</p>
