title: Encrypting Parameters across controllers
body: <p>I need to pass a parameter from one method in a controller to another.  </p>
  
  <p>From my understanding I have to pass the parameters as a <code>GET</code> exposing it in the url string.  </p>
  
  <p>What is the best way to encrypt the data so no one can see what is actually getting passed in the string?  Also, is there a way to pass it via <code>POST</code> or is my original understanding correct?</p>
