Basic Image Encryptor Using Bitwise Operations

Requirements

• Python 3.8+
• OpenCV2 for Python installed.
• Numpy installed.

---

Bad Description and Demo

Encrypts an image by generating a random byte key then XORing it with an input image. Can do AND and OR operations for demonstration purposes.

Example usage using the files in example_files.

# Encrypts the image using XOR, AND and OR operations using random bytes
python3 image_crypto.py -A alan-turing.png

# Decrypts the XOR image to get the original image again.
python3 image_crypto.py -o decrypted -k image.key out-xor.png

Only use lossless image compression formats such as .png
