Question About Cracking other versions of Enigma

[Smiril]

Hello .... on Linux Debian it cracking really fast but only with the given "plug" and given "rotors" ....

is there a way to rewrite your code to crack this one: https://github.com/Smiril/Kortin-Enigma.git

the given Cyper "FTMW" is translated to "THAT" with plug "AT ME" should be "TEST" and not "THAT" ... yes there are differences in rotors and this "MSG" is from an 5 rotor ... means 5 order (1-9), 5 rings (A-Z), 5 pos(A-Z) , 1 reflector 26(A-Z)once , 1 notch 5(A-Z)once , 1 plug 10(A-Z)once translated: 5 ROTORS(5x26LETTERS), 5 WHEEL(5x1-9), 5 START(5xA-Z), 5 RINGS (5xA-Z), 1 REFLECTOR(26LETTERS), 1 NOTCH(5LETTERS), 1 PLUG(10LETTERS)

the Turing Code is also different from your code in my version ...

your output below ...

I don't think there is a way to rewrite the code for your ciphertext "FTMW". The problem is, "TEST" scores at -4.392 and "THAT" scores at -2.575, so "THAT" will always win out. This can happen with short ciphertexts because there are multiple valid decryptions. If you make your ciphertext longer, then you should be able to find a unique decryption for it. If you are testing your Enigma project output to mine for validation, that is what I suggest.

With a more extensive rewrite, I may be able in the future to combine equal plaintexts on the scoreboard so that it shows more alternative solutions. I put this in my TODO for later analysis.

In cryptography, there is the concept of unicity distance, where a ciphertext shorter than the unicity distance will have multiple valid decryptions. According to a paper I found on cryptocellar, the unicity distance for Enigma is 23 characters. So if you want a unique decryption for testing, make your ciphertext longer than 23 characters.

Thank you for this information

I added on my todo list for this week You said longer than 23 letters … I will Test it
