ELGAMAL CRYPTOSYSTEM KEY GENERATION, ENCRYPTION, DECRYPTION, AND DIGITAL SIGNATURES: LEARN BY EXAMPLES WITH PYTHON AND TKINTER

This book presents an interactive Python application that showcases the ElGamal encryption algorithm through a user-friendly Tkinter graphical user interface (GUI). The application allows users to generate ElGamal keys of various sizes, view them in multiple formats (raw integers, hexadecimal, Base64), and use these keys for encryption and decryption. The GUI simplifies key management and demonstrates ElGamal encryption's effectiveness in securing data, making it a valuable tool for both educational and practical applications. In addition to key management, the application includes features for encrypting and decrypting sensitive data, such as credit card numbers and transaction details, using synthetic datasets. The interface is designed with tabs to facilitate easy navigation through key generation, encryption, and decryption processes. Users can also visualize encrypted and decrypted data with interactive graphs, making it easier to understand the impact of encryption. This comprehensive tool integrates cryptographic techniques with data visualization, providing a robust platform for exploring and applying ElGamal encryption in real-world scenarios.
