title: Can the encrypt class in code igniter be used to send secure data in URL?
body: <p>I try to send variable through URL. So I use this CI method</p>
  
  <pre><code>$this-&gt;encrypt-&gt;encode($variable)
  </code></pre>
  
  <p>And i decode it in the destination. but it doesn't return a correct value.
  encoded value example :</p>
  
  <blockquote>
    <p>pWI+q72keVNJtpaZgJdxfwuKtqM2VrNMGhpnknsrf/3dadh0x+lU70h9hgSwFzTWQAEclSfoSZ2J3/UOuLVwgA==</p>
  </blockquote>
  
  <p>I realize there are too much special characters here such as <code>+/=</code> . And to allow these characters in URI will be unwise.</p>
  
  <p>If that so, is this function can't be implemented to secure data sent through URL?</p>
