enigmator 1.0.4

Package for decrypting messages with an enigma machine

De(s)cription

This is a python package for enrypting messages with the historic enigma machine. I spent quite some time trying to find a suitable existing project and ended up implementing it myself.

This library answers the question no one asked:

"How can I annoy my surroundings by sending them trivial encrypted messages and make them go through the process of deciphering?"

No dependecies to other python packages necessary to decrypt messages and free for use and further adaption (MIT license).

Usage

from enigmator import (ROTOR_I, ROTOR_II, ROTOR_III, ROTOR_IV, ROTOR_V,
                       REFLECTOR_A, REFLECTOR_B, REFLECTOR_C,
                       Enigma,
                       Plugboard)

EnigmaMachine = Enigma(reflector=REFLECTOR_B, 
                       left_rotor=ROTOR_III, 
                       middle_rotor=ROTOR_II, 
                       right_rotor=ROTOR_I, 
                       rotor_positions="16 10 1",
                       ring_positions="3 1 17",
                       plugboard=Plugboard("CE KL FP MD")
                       )

x=EnigmaMachine.encipher('Jeder Mensch sollte wissen, wie man Enigma-Maschine verwendet.')

print('Result is:')
print(x)

Result is:

LVUBS FKTKJZ EXDYQP XFYEHV, AZS BVR WBGXXW-CTYXLRDK LMTLDALNQ.

To decipher back to plain text, just pass the decypted text back into the EnigmaMachine:

EnigmaMachine.encipher('LVUBS FKTKJZ EXDYQP XFYEHV, AZS BVR WBGXXW-CTYXLRDK LMTLDALNQ.')
