🛡️ AES-RSA Hybrid Encryption System

A professional Python-based security tool that demonstrates Hybrid Cryptography by combining AES-256 for data encryption and RSA-2048 for secure key management.

Features

• Hybrid Core: Combines AES-GCM speed with RSA-OAEP security.
• Integrity Verification: Uses SHA-256 hashing to ensure data hasn't been tampered with.
• Modern GUI: Built with Tkinter featuring a real-time system log.
• Performance Tracking: Measures execution time for both encryption and decryption.

How it Works

The system follows the KEM/DEM paradigm:

1. AES encrypts the bulk data (JSON records).
2. RSA encrypts the AES session key.
3. Both are bundled into a single .bin file for secure storage.

Installation

1. Clone the repo: git clone https://github.com/MariamAshraf25/AES-RSA-Hybrid-Encryption-System-
2. Install dependencies: pip install -r requirements.txt
3. Run the app: python app_gui.py

Security Note

Note: For security reasons, RSA keys are generated automatically on the first run and are ignored by Git.
