title: Ways to Encrypt and decrypt array in jquery
body: <p>I am completly new to jquery and client side programing. I am trying to figure out a way of achiving this:</p>
  
  <ol>
  <li><p>On the client side I have a hidden user id/profile id, which I wanna to encrypt, but while manipulating the hidden value, I have to decrypt and perform some operation on it.</p></li>
  <li><p>I have a global array of arrays like below:</p>
  
  <pre><code>var users=[{"u_id":"1234", "u_name":"Test"},{"u_id":"12345", "u_name":"Test1"}];
  </code></pre></li>
  </ol>
  
  <p>this array is used by various other compoenets, e.g. when user mouse-over on the profile-id, it will get the details from the above array and display the result to him.</p>
  
  <p>In short, I want to encrypt/decrypt all my global variables inside the script.</p>
  
  <p>any plugin or ways to do will be highly appricated.  </p>
