title: Base64 encode/decode without padding on golang ( appengine )
body: <p>There's a way to encode/decode a string to/from Base64 without having the padding at the end? I mean the '==' ending.</p>
  
  <p>I'm using <code>base64.URLEncoding.EncodeToString</code> to encode and it works perfectly but I didn't see a way to decide to not use the padding at the end ( like on java ).</p>
