Python and JS implementations of the Vigenère Cipher
The dependencies for the Python version are mostly formatting-related, and can
be installed with pip install -r requirements.txt.
The implementation is all in the vigenere.py file; it can be
used by importing (e.g.: from vigenere import Vigenere) and then
instantiating the class (v = new Vigenere()) and using its encrypt and
decrypt methods. The parameters are documented in the source code.
The test_vigenere.py file contains the unit tests for the
implementation and can be run with python3 -m unittest test_vigenere.py.
The cipher itself is implemented in pure JS in the
vigenere.js file, from which the transform
function can be imported and used. The parameters are documented in the source
code.
There's also a web app
(available here) with an
interface for applying the cipher, implemented in Svelte. To run this app,
first install the dependencies with npm i then use the dev server with
npm run dev, or use npm run build to generate the bundle or
npm run preview to better test it.
