title: Security of Isolated Storage on Windows Phone 7 and Network Transfers
body: <p>In my game I plan to save the users highest score to then be transferred to my server at a later time, I was planning to do this by saving the score in a .txt file in Isolated Storage.</p>
  
  <p>What precautions should I take to avoid users from editing the file itself or being able to spoof packets to trick the server into saving fake scores?</p>
  
  <p>I'm considering encrypting the data before saving in a way my server can read later on.</p>
  
  <p>So how secure is Isolated Storage?
  What encryption should I look at implementing considering my App is .NET(C#) and my server uses PHP.</p>
