title: Delphi 7 Generate key for my program online (delphi 7 licensing)
body: <p>I wanted to add to my program a simple key protection.
  so if they got to my website.com/key.html it will generate them 1 key.
  that is usable once in my app. and cannot be used again.</p>
  
  <p>Is that easy? anyone have code for that?</p>
  
  <p>Thanks a lot!</p>
