ATTENTION on Deck!

[donw]

To ALL GWX SH3 players!
If you have'nt already done so, head over to the http://www.subsim.com/radioroom/clear.gifSH3 Mission Designers' Forum (http://www.subsim.com/radioroom/forumdisplay.php?f=198)

and download ACSoft's "Secret Mission" single player mission! :rock:

It is VERY well written and uses a (included) Enigma machine simulator that is used to decode received radio messages thru out the mission!

Directions received must be followed precisely to complete mission objectives.
LOADS of fun! :up:

Sounds good, thanks:up:

[Mooncatt]

it does sound good well worth a download

When using the Enigma machine I don't totally understand the "Kengruppen" part of the code.

It says that the it was the secret daily key but in another example it says that a 5 letter sequence at the beginning of a coded sequence is a kengruppen sequence used to determine which key it is. I don't understand that part exactly.

ATTENTION !!!

I am very sorry about that, but unfortunately, the file "CODEBOOK 1942 8.txt" had an error. This is now corrected.

For those who had already downloaded the mission, please, have a look here:

You will found a message where you can only download the corrected file.

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.

ACSoft,
I need a link to the enigma machine

Everything is included (including the machine) with ACSoft's file located in the mission designers forum under "A little gift for you: ACS Secret Mission 1"

[irish1958]

DONW.
thanks; go big red!

[donw]

Yowzas!
I finally completed the mission objectives for this EXCELLANT homemade mission, and all I can say is, if you have'nt tried it yet...you're missing out!!

The bad guys are REALLY bad and you MUST follow every received radio message (all coded with the Enigma simulator). I had an armed trawler hound me to death, but finally managed to slip away. (At this point, I was not allowed to attack)

Give it a try folks...you'll be glad you did! :up:

The only thing putting me off is all that enigma stuff... :nope::down:

It really is not all that complicated once you have done a cpl decodings. :up:
