Hello Kaleun !!!

Although the documentation of the Enigma machine is very complete, here is a summary of how to use the machine. This might speed up a little your study and understanding of this complex decypher system.

Enigma hardware setup:

--------

Take the date of the message and select the according line in "CODEBOOK 1942 08.txt"

AUGUST 10 - 16 - PSK ZSG - YMLM ....


| 10 | B | III I VIII | 18 25 13 | BE CT DX FH IM KY NS PR UZ VW | SVD LKP XNJ JRF |

--------

Open the front part of the Machine.

Select the Enigma machine type ( the letter on the large cylinder)

| 10 | B | III I VIII | 18 25 13 | BE CT DX FH IM KY NS PR UZ VW | SVD LKP XNJ JRF |

Obviously, it must be:

Kriegsmarine M3 - UKW = B

--------

Select, set and place (from left to right) the wheels

| 10 | B | III I VIII | 18 25 13 | BE CT DX FH IM KY NS PR UZ VW | SVD LKP XNJ JRF |
| 10 | B | III I VIII | 18 25 13 | BE CT DX FH IM KY NS PR UZ VW | SVD LKP XNJ JRF |
| 10 | B | III I VIII | 18 25 13 | BE CT DX FH IM KY NS PR UZ VW | SVD LKP XNJ JRF |

Example: First wheel is wheel number III coded on 18

Close the front part of the machine

--------


Open the front wiring side of the machine.

Wire the machine on the front side:

| 10 | B | III I VIII | 18 25 13 | BE CT DX FH IM KY NS PR UZ VW | SVD LKP XNJ JRF |

Example "BE" mean: click on "B", then on "E" on the panel. This simulate the "B" wire plugged into "E".

Close the front wiring side of the machine.

--------

Message decoding:

--------

Set the starting decypher code on the wheels

AUGUST 10 - 16 - PSK ZSG - YMLM ....

Type "ZSG". This will give you the message key in clear

--------

Set the message key on the wheels

Now you are ready to decode the whole message by typing all groups of 4 characters.

--------


Good luck for this adventure and let me know if you liked this style of single mission. This might motivate me to write some more "Secret Missions" for you all.
