Cryptography Tool

Description This Cryptography Tool is a Python-based application that implements various classical ciphers. It provides both a command-line interface for direct interaction and a Flask API for web integration. The tool supports multiple cipher methods including Caesar, Vigenère, Playfair, Rail Fence, and Atbash ciphers.

Features

• Caesar Cipher (encode, decode, brute force)
• Vigenère Cipher (encode, decode)
• Playfair Cipher (encode, decode)
• Rail Fence Cipher (encode, decode)
• Atbash Cipher (encode/decode)
• File handling (read from file, write to file)
• Key generation for Vigenère and Playfair ciphers
• Command-line interface for easy interaction
• Flask API for web integration

Usage

Command-line Interface To use the command-line interface, run:

python cryptography_tool.py

Follow the on-screen prompts to select and use different cipher methods.

Testing

To run the unit tests, choose option 15 from the main menu in the command-line interface, or run:

python -m unittest cryptography_tool.py
