Thanks for the nice article. I have a question regarding about encryption. In WP7.5, socket is supported. So I am using socket to communicate an window phone application (app) with the server. I want to know if I have to encrypt the data or not....Oh.. I feel stupid about asking this... There will be 2-way communications (app to server, server to app) using socket and some data can be sensitive. There will be a decent amount of communication between the app and the server. Is using your encryption technique a good idea for this case? And also, to enable 2-way encrypted communication, the server and the app both will have to have password&salt generated. right? I am sorry for my bad english. Hi Rob!

Once that key is created, you could reuse it to encrypt multiple strings to be stored in Isolated Storage on Windows Phone. Dealing with servers get tricky since the server would need the same key you created on the device in order to decrypt. Unfortunately, Windows Phone 7 doesn't include the capabilities needed to maintain secure key storage. This is why the user is required to enter their credential each time in order to encrypt/decrypt the local data. The lack of no automated key management makes what you're asking for very difficult. -Rob Hi Mike,

You said if you have to encrypt multiple strings use pre created keys. What exactly does that mean? Basically what I'm trying to do is send a high score to a server but I want it encrypted. I'm sending 3 strings to the server so the server and the app need to have synced keys right? How do I create a pre created key with it being secure that I can use both in my app and server?
