title: Codeigniter Encryption Key
body: <p>Say I have this set up as my encryption key and I already have the encrypt library on autoload:</p>
  
  <p><code>$config['encryption_key'] = 'bjA{&lt;ATCs1w5?,8N(bJvgO3CW_&lt;]t?@o';</code></p>
  
  <p>How do I use it in an encrypt function?</p>
  
  <pre><code>function s()
  {
      $something = $this-&gt;encrypt-&gt;encode('eoaighaeg',$key);
      echo $this-&gt;encrypt-&gt;decode($something, $key); 
  }
  </code></pre>
  
  <p>^ Non working example to give you an idea.</p>
