@bbad: Enigma is a very sophisticated cipher system. If you dont understand it, read up on it at Wikipedia and the authors web site.
This is a great implementation of several different Enigma machines. It works great as advertised. I wish it had a landscape mode, and I wish I could figure out how to get the alt keyboard thats shown that has numerics, but that is not a criticism.
The program is DEFINITELY worth two bucks!
