You can't decode Proud's messages unless you know the rotors, rotor start keys, and rotor ring keys he used for his messages. I have been doing my research on enigma :)

Essentially, the only way you can decipher his messages is if you know the key. That is the main reason the Allies had a tough time cracking Enigma. And even if you found the key, you would have to still use process of elimination to decipher the message, trying to figure out each letter of the message, and then making a well educated guess on what it says. If you're confused on what I mean, here is a cool website explaining how Enigma works. You can even use it to create your own messages.
