In this example, EINEIN emerged on the lamps, so the operator would learn the message setting that the sender used to encrypt this message. Design weakness and operator sloppiness in these indicator procedures were two of the main weaknesses that made cracking Enigma possible. The plugboard contributed more cryptographic strength than an extra rotor. The additional rotors were marked VI, VII and VIII, all with different wiring, and had two notches, resulting in more frequent turnover. After setting up his machine, he would type the message on the Enigma keyboard. The procedure had the operator set his machine in accordance with the secret settings that all operators on the net shared. Current flowed from the keyboard through the plugboard, and proceeded to the entry-rotor or Eintrittswalze. A four-rotor Enigma machine is on display at the Military Communications and Electronics Museum at Canadian Forces Base (CFB) Kingston in Kingston, Ontario. The operator turned his rotors until AOH was visible through the rotor windows. The Germans mistakenly believed the Allies would not be able to break the codes. The operator would next press N, and then X in the same fashion, and so on. This was achieved by a ratchet and pawl mechanism. Early models were used commercially from the early 1920s, and adopted by military and government services of several countries, most notably Nazi Germany before and during World War II. The demonstration represented a vital basis for the later British continuation and effort. The military Enigma connects them in straight alphabetical order: A→A, B→B, C→C, and so on. The first five rotors to be introduced (I–V) contained one notch each, while the additional naval rotors VI, VII and VIII each had two notches. This model was equipped with a counter that incremented upon each key press, and so is also known as the 'counter machine' or the Zählwerk Enigma.

The Enigma machine is an encryption device developed and used in the early- to mid-20th century to protect commercial, diplomatic and military communication. Rotors were marked with Roman numerals to distinguish them: I, II, III, IV and V, all with single notches located at different points on the alphabet ring.

Prior to encryption the message was encoded using the Kurzsignalheft code book.
