title: URL encryption in codeigniter
body: <p>I want to encrypt the url in codeigniter. </p>
  
  <p>My ultimate goal is encrypt everything after the domain.
  example.com/controller/function/itemid
  to
  example.com/sdfsdfsff/sdafaergdfsd/dfesDEWrewF</p>
  
  <p>I can use the ci's "encrypt" library in my controller to encyrpt/decrypt the itemid but is there any other way to do encyrtpt everything in the url?</p>
