title: iPHone - AES 256 encryption without padding
body: <p>I've seen some of the posts for AES 256 encryption on iphone usign cocoa.
  One of the post is <a href="http://pastie.org/426530" rel="nofollow">http://pastie.org/426530</a>
  But all the posts are using some kind of padding. How can I use AES256 encryption without using any padding?</p>
  
  <p>Because, I'm communicating with a server on which encryption/decryption is handled without padding. But on iphone, I can use kCCOptionPKCS7Padding or kCCOptionECBMode modes only. How can I code my iphone app so that encryption/decryption happens successfully?</p>
