title: PHP Code Igniter Encryption doesn't return anything
body: <p>when i load my controller i have this:</p>
  
  <pre><code>$this-&gt;load-&gt;library('encrypt');
  
  $get = null;
  parse_str($_SERVER['QUERY_STRING'],$get);
  $email = $this-&gt;encrypt-&gt;decode($get["acc"]); // e.g.  www.lol.com/?acc=troll
  </code></pre>
  
  <p>And my controller is called like this:</p>
  
  <pre><code>$this-&gt;load-&gt;library('encrypt');
  $this-&gt;load-&gt;helper("url");
  $user = $this-&gt;input-&gt;post('email', true);
  
  $encrypted_string = $this-&gt;encrypt-&gt;encode($user);
  redirect('account/viewaccount?acc='.$encrypted_string);
  </code></pre>
  
  <p>The url looks like this:</p>
  
  <pre><code>http://localhost/CodeIgniter/index.php/account/viewaccount?acc=+fgSAs6X7ysW6XDjFVw//9RGVbY751zZv1LQ44yYBjhVuzI1BC1t9BbZCIUdX5lpYA==
  </code></pre>
  
  <p>But the problem is, when i encode i get a value, but then later on, when i decode this huge value (I can receive this value flawless, by testing) it returns nothing, just NULL.</p>
  
  <p>Why is this happening?</p>
  
  <p>Thank You</p>
