title: Apply hashing to secure passwords generated within the app
body: <p>I have a created 150 odd predefined passwords and usernames in my windows phone 8 app.</p>
  
  <p>They get initialized whenever the app starts.</p>
  
  <p>Whenever a user enters the password and username, the app checks its authenticity and acts accordingly.</p>
  
  <p>For obvious security reasons, i would like to protect my passwords so that the "extra-genius minds" don't find a way to manipulate them in their own app.</p>
  
  <p>Could anyone tell how to use SHA-1 hashing and store those passwords into hashed formats.</p>
  
  <p>Thanks!</p>
