Reads an input image. Iterates through each pixel's RGB values. Shifts each color value by the specified amount (default: 50). Wraps shifted values around 0-255 for color bounds. Creates a new image with encrypted pixel values. Saves the encrypted image as "encrypted_image.png".
Reads an encrypted image. Reverses the shifting process for each pixel. Creates a new image with decrypted pixel values. Saves the decrypted image as "decrypted_image.png".
