title: C# very simple string encryption for game
body: <p>I am making a small game on Unity using c#. It is basically a 2d side scrolling runner type game. I measure the time taken by each player to finish the game and it is stored on a float. I would like to put this in a string along with a salt word, and display an encrypted code to the player. </p>
  
  <p>The code has to be small enough to be comfortably written down by the player. I should be able to decrypt the code which the player would send me, and figure out how much time he/she took to complete the game. </p>
  
  <p>Please tell me how I should proceed in doing this. most of the algorithms i saw online are very complex and generate large blocks of encrypted text.</p>
  
  <p>Thanks in advance.</p>
