Mini209 is a complete M-209 cipher machine simulator for your Apple iOS.

Basically, the M-209 was a cipher machine used by the U.S. Navy during World War II for the encryption and decryption of secret messages. It looked like an old typewriter with some extra features, and no keyboard :)


You can use Mini209 to encrypt messages, send encrypted messages by email or decrypt messages sent to you. Being fully compatible with the real M-209 means you can also use Mini209 to decode any of the original messages which can be found on Internet.

Mini209 supports Copy/Paste to allow you to interact with any other application on your device. You can even copy/paste machine configurations (Key settings) to send them along :)
