title: ruby - how to encrypt text
body: <p>I need to encrypt a string (from a text area) that will also be decrypted later on when it is displayed.</p>
  
  <p>I'm not to concerned about it being majorly secure, but just don’t want to store the data in plain text format.</p>
  
  <p>Does anyone have any suggestions on how to do this easily in Rails?</p>
