BEFORE USING THIS MOD PLEASE READ THE MANUAL TO UNDERSTAND WHAT IT IS AND HOW TO USE IT!


Watch this great video tutorial by POTUS if you're still confused after reading the manual:




----------
Original Post:



This Enigma mod is the result of a lot of hours of work doing historical research, learning Python, learning SH5’s menu interface through a lot of trial and error, countless CTDs, designing graphic elements for the Enigma interface, etc.

There is a .txt file in the documentation folder explaining what needs to be changed to make the Enigma mod compatible with other installations, this text is intended for modders or advanced users.



Features:

1 - A fully working "Schlüssel M" model M4 naval Enigma:

It is accessible through the radio operator’s menu:




The machine’s UI layout was inspired by Dirk Rijmenants’ popular Enigma simulator:





2 - Implementation of actual Kriegsmarine cipher networks used during the war:

Cipher networks were used to send messages to U-boats in different geographical areas. U-boats were issued envelopes with their assigned cipher network settings before going on patrol. This mod implements cipher networks for different geographical areas with their own daily settings.

3 - Implementation of the Kenngruppen system used by the Kriegsmarine for U-Boat messages.

This is better explained in the manual.

Some of the in-game key sheets and tables implemented:

Substitution tables, used to decipher the indicator group:

4 – An external message application to encrypt messages.

Modders or users are able to add messages related to campaign events or mission objectives. Part II of the manual provides guidelines on how to write messages for Enigma encryption.

Known (small) bug: The loading screen’s font switches from the default one to the “Chalk” font. I haven’t figured out how to fix this yet.
