AES Image Encryption Project

Overview

This project focuses on encrypting and decrypting images using the Advanced Encryption Standard (AES) algorithm in Python. The implementation utilizes the Pillow library for image processing and the pycryptodome library for AES encryption. The encryption is done in Cipher Block Chaining (CBC) mode, and a random key and Initialization Vector (IV) are generated for enhanced security.

Prerequisites

Ensure that you have the required libraries installed before running the code:

pip install Pillow
pip install pycryptodome

Project Structure

main.py

The main script, main.py, encompasses the following functionalities:

• Validates image files
• Generates a random key and IV
• Derives a password-based key using PBKDF2
• Calculates HMAC for data integrity

Running the Script

Execute the script by navigating to the directory where main.py is saved and using the following command:

python main.py

image_crypto.py

The second script, image_crypto.py, provides a simplified approach to image encryption and decryption using the pycryptodome module. However, this script is currently not working as intended.

Usage

1. Encrypting an Image

1. Run the main.py script and provide the path to the image when prompted.
2. The script will generate a random key and IV, encrypt the image, and save the encrypted image.

2. Decrypting an Image

1. After encrypting an image with main.py, use the provided key and IV to decrypt the image using the main.py script.

3. Troubleshooting image_crypto.py

If you encounter issues with the image_crypto.py script, consider reviewing and adjusting the code based on specific requirements. Thoroughly test the script with various scenarios to ensure correct functionality.

Important Note

This example assumes the use of a random 128-bit key for AES encryption. In a real-world scenario, key management is crucial, and secure methods for key generation, storage, and exchange should be considered.

Feel free to adapt the code based on your project's requirements and conduct extensive testing to ensure its reliability.
