BASIC PROCEDURE
Decrypting a Kriegsmarine 4-rotor message
Note: The Kriegsmarine 4-rotor Enigma machines (M4) are more complex than the 3-rotor Wehrmacht versions. This procedure takes for granted that you already know the basic Enigma operating steps that are used with the 3-rotor machines and that you are ready to advance to a more challenging level of Enigma activity. We have selected the sample message from the Basic Procedure Encrypting and Sending a Kriegsmarine 4-Rotor Message as our example in this procedure. You will, of course, use your own received message to decrypt.
