title: HowTo Crypt/Encrypt some string (e.g. Password) on Qt simple
body: <p>Here what I have got:</p>
  
  <ul>
  <li>Qt SDK version 4.6.2</li>
  <li>Windows XP</li>
  </ul>
  
  <p><strong>Question:</strong> how can I simply crypt and encrypt simple <strong><em>QString</em></strong> value? I need this to be able to save some crypted string into the INI file, and after reopening application encrypt string to normal password string value.</p>
  
  <p>PS: I'm looking simple and nice solution.</p>
  
  <p>Thanks for help!</p>
