Enigma – Mission X Challenge Accomplished with Python

Enigma M3 from 101 computing: https://www.101computing.net/enigma/
GitHub Repo: https://github.com/cuicaihao/Enigma-Mission-X

Short Summary

Inspired by Enigma – Mission X Challenge, this repo is used to save the research and practice efforts in Different Cipher methods.

The primary goals are using Python programming language to achieve targets listed as follows in Jupyter Notebooks:

Example

  • German Navy Ciphertext by Enigma M3: OJSBI BUPKA ECMEE ZH
  • German Message: Ziel hafen von DOVER
  • English Translation: Target port of DOVER
Enigma Mission – X

By running the notebook, it is not difficult to complete the deciphering process with the “keys” to get the original message from the ciphertext by the German Navy.

Notebook Outputs Example

However, it will be difficult to break down the cipher without knowing the keys. That will be the Turing-Welchman Bombe Simulator challenge.

About Enigma Mission X

Mission X is a game for programmers to accomplish the deciphering job required by Dr Alan Turing.

Programmers need to break the secret with limited information as follows.
