AES Encryption in Windows Phone 7
===

I'm trying to implement this utility class I found on [gutgames][1] by James Craig, (you can view the class [here][2]) with Windows Phone 7.

I had to replace all the references to System.Text.Encoding.ASCII to System.Text.Encoding.UTF8 since ASCII apparently is not supported in WP7. Besides that I'm still getting some errors because of references / namespaces not being found:

 - PasswordDeriveBytes
 - RijndaelManaged
 - CipherMode

Firstly I don't have a clue what this is, secondly, are there any classes that I can use to replace these that indeed will be available in the Windows Phone 7 framework?

Thanks!
