Encription method available also for webplayer??

Hi all,

in my project I read and write a XML for some user info. I need to encrypt that XML for security reasons, so I have used the namespace System.Security.Cryptography and inside it, the AesManaged class.

All worked ok until I build the project for webplayer. I saw in the compatibility section of the Unity reference

http://unity3d.com/support/documentation/ScriptReference/MonoCompatibility.html

that the AesManaged class appears in red for the Web Player, so I understand that I can not use it although it works for standalone builds.

So, my question is what method/libraries/classes I could use to encrypt/decrypt my XML that works both in webplayer and in standalone?

thank you very much!

Bump. This sounds important.
