CryptoTools

CryptoTools is a terminal user interface implementing classical ciphers like the Caesar or Vigenere cipher, as well as the Enigma machine. It has some cryptanalysis features for breaking simple ciphers.

It currently supports:

• Enigma machine
• Caesar cipher
• Affine cipher
• Vigenere cipher and its variants: Beaufort cipher and autokey/autoclave cipher
• Index of coincidence calculating
• Cryptanalysis of several ciphers:
  • Caesar cipher
  • Affine cipher
  • Vigenere cipher (including key length finding)

Installation

git clone https://github.com/Cubix1729/crypto-tools.git
cd crypto-tools
pip install -r requirements.txt

To run the CLI:

python ./src/global_interface.py

Usage

Use the up and down arrow keys to navigate in a menu and press enter to confirm a choice.
Pressing Control-C will exit the current interface.

Dependencies

• InquirerPy used for making the interactive command-line interface
