gremmie / enigma

A historically accurate Enigma Machine simulator written in Python 3.

Hi, I'm Brian.

I created some WWII crypto simulators in Python. They were hosted for a long time on bitbucket in Mercurial repositories. They have been moved here to GitHub after bitbucket dropped support for Mercurial.

I'm interested in Python, Django, web development, Dart, & Flutter.

enigma's Issues

Test cases not working in command line or with key files

Hi. I can run your test program (in Python) fine:

[kipingram@lenovo]$ python test
BLA
THEXRUSSIANSXAREXCOMINGX

I modified it to print message key - that's the BLA above. As you see, the plaintext emerges.

But, when I try to use the command line utility as follows, it fails:

[kipingram@lenovo]$ ./pyenigma.py -r II IV V -u B -i 1 20 11 -p AV BS CG DL FU HZ IN KM OW RX -s WXC -t KCH
JRA

I've stared at the test program until I'm blue in the face, and as far as I can tell I've properly carried the settings over to the command line.

Any thoughts? I did this with a key file as well, and got JRA there too.

Here is the key "settings" part of the test python:

machine = EnigmaMachine.from_key_sheet(
       rotors='II IV V',
       reflector='B',
       ring_settings=[1, 20, 11],
       plugboard_settings='AV BS CG DL FU HZ IN KM OW RX')

# set machine initial starting position
machine.set_display('WXC')

# decrypt the message key
msg_key = machine.process_text('KCH')

Also, I modified the provided little keys.txt file so that today (the 10th) was one of the lines, and I tried to put in the same settings as above:

10 II IV V 1 20 11 AV BS CG DL FU HZ IN KM OW RX B
30 Beta II IV I A A A V 1/20 2/12 4/6 7/10 8/13 14/23 15/16 17/25 18/26 22/24 B-Thin
