Secure Hybrid Encryption & Digital Signature

This project is an end-to-end cryptography application that combines hybrid encryption (AES-GCM + RSA-3072) and digital signatures to ensure data confidentiality and integrity. The user interface is built with Tkinter, and cryptographic operations are handled using the PyCryptodome library.

Features

• Hybrid Encryption: Uses AES-GCM for data encryption and RSA-3072 for encrypting AES keys.
• Digital Signature: Generates and verifies digital signatures to ensure data integrity.
• Intuitive User Interface: Select files to encrypt or decrypt through a graphical interface.
• Metadata Management: Encrypted files include metadata to preserve the original file extension.

Prerequisites

• Python 3.8 or higher
• PyCryptodome library

Installation

1. Clone this repository:

   git clone [email protected]:Sharingan-Team/innov-digital-encryption.git
   cd innov-digital-encryption

2. Install the required dependencies:

   pip install pycryptodome

Usage

1. Run the application:

   python crypto_simulation.py

2. A graphical interface will open with the following options:

   • Select File to Encrypt: Choose a file to encrypt.
   • Select File to Decrypt: Choose an encrypted file to decrypt.

3. Follow the on-screen instructions to encrypt or decrypt your files.

Project Structure

• crypto_simulation.py: Main entry point of the application.
• crypto_ui.py: User interface built with Tkinter.
• crypto_utils.py: Utility functions for encryption and digital signatures.
• README.md: Project documentation.

Security

• RSA keys are dynamically generated for each session.
• Encrypted files include a digital signature to ensure their integrity.
• Metadata is securely encoded to preserve file extensions.
