title: Any cocoa source code for AES encryption decryption?
body: <p>I am searching for some cocoa code on AES encryption and I did some google search for it. I found this very useful link - 
   <a href="http://iphonedevelopment.blogspot.com/2009/02/strong-encryption-for-cocoa-cocoa-touch.html" rel="nofollow noreferrer">http://iphonedevelopment.blogspot.com/2009/02/strong-encryption-for-cocoa-cocoa-touch.html</a>. So I tried it but it did not work for me.</p>
  
  <p>Can anyone suggest me some useful link or source code which can help me to implement it in my sample application.</p>
