This project performs the decryption of classical ciphers using the Metropolis Algorithm.
- In order to compile the files, you'll need to have Python installed.
- The script used in this project also needs the package
numpy, which can be added with the following commands:
# Best practice, use a virtual environment rather than install in the base env
python -m venv venv
.venv\Scripts\activate
# The actual install command
pip install numpy
- The repository already has a probability matrix file and some encoded texts to run as an example.
- The script should work with any encrypted text, as long as the cipher used to encrypt it was a simple substitution cipher, transposition cipher or substitution-plus-transposition product cipher.
