title: Java - store sensitive data
body: <p>I develop application with Java.
  I need to store some initial configuration data in some kind of file.</p>
  
  <p>I want my app to be able to read this data, but I don't want user to do so.</p>
  
  <p>Example : application loads IP from encrypted file. User sees like "dsda@#21da@" so he won't bother doing anything :)</p>
  
  <p>How should I do such a thing?
  Thanx!</p>
