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.
