Enigma machine emulator

Python
Object-oriented Python 3 emulation of the Enigma M3 cipher machine, with rotors and reflectors as first-class classes.
Personal project
Idea
Reading about the Enigma cipher and Turing’s role in breaking it sent me down the rabbit hole. I watched a couple of documentaries, then implemented a virtual one in Python. The result is a faithful Python 3 emulation of the Enigma M3, modeled object-oriented with the machine and its components — rotors, reflectors, plugboard — as first-class classes.
Implementation
Each component is its own class with a clean substitution interface, so the machine itself is mostly orchestration over component composition. Settings are reproducible, which makes encrypt-then-decrypt round trips straightforward to verify.
Stack
Python 3, no external dependencies.
