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:
- Revisit Basic Cipher Methods
- Digital Enigma Cipher Machine Emulator
- Turing-Welchman Bombe Simulator
- Story Telling & Knowledge Sharing
- python 3.11 (use conda or pyenv)
- pandas
- matplotlib
Python 3.11 is used for development work, and I believe python version 3.8, 3.9, 3.10 are all OK. FYI, python 3.11 is about 25% faster than 3.10python-speedy for details.
You will need to install pandas and matplotlib for Excel operation and plot figures.
Take a step by step tutorial by notebook:Chapter_B_Enigma to develope a Enigma Machine in python.
Eventually, use the Enigma Cipher Machine Emulator to accomplish the Mission X.
Here is the final output for the code for the Mission X.

Take a step by step tutorial by notebook: Basic_Cipher, this will help you to get a better understanding of the Enigma machine.
Basic Letter 1 to 1 mapping like Caesar Cipher is very easy to be hacked by comparing and matching letter based on statistic.
By create a multiply mappings and rolling the letter mapping by order, we can mapping the same letter to a different letter in each around, lead to a more even distributed ciphertext.
