MessageDecoderApp

Overview

MessageDecoderApp is a tool for quickly encrypting and decrypting messages. It employs NLP and cryptography techniques to detect patterns in encrypted text and accurately decrypts them.

Features

• Encryption & Decryption: Utilize the Caesar Cipher and Vigenere Cipher for secure message handling.
• Classify ciphers: The MessageClassifier module can distinguish between Caesar and Vigenere Ciphers with 97% accuracy.
• User-Friendly Interface: The classifier autonomously recognizes and solves messages, eliminating manual cipher identification.

Requirements

• Python 3.10.8 (Note: Not compatible with Python 3.11)
• Kaggle API credentials
• Additional libraries as per requirements.txt

Installation

1. Clone the repository to your local machine.
2. Install dependencies using pip install -r requirements.txt (recommended within a virtual environment).
3. Add your kaggle.json API credentials in the data directory.
4. Run the setup.h script to download the data.csv file (227 MB).

Usage

• Execute __init__.py to start the application.
