title: how to encrypt plist file either common crypto or security transforms?
body: <p>I have data in plists in an iPhone app that I want to encrypt.
  Reading Apple Common Crypto and Security Transformations documents.</p>
  
  <p>Any suggestions on best way to encrypt the plists (common vs transforms)?</p>
  
  <p>Additional security related question...(yes nothing is 100% secure)...
  If a method uses a proprietary algorithm and someone puts the app through something like class-dump-z will they be able to see the algorithm?</p>
