I need help regarding some ideas for encryption and decryption of images.
I want to encrypt/ decrypt the images and use them to prevent unauthorized users from substituting my images with their ones. I have the code for encryption/ decryption with AES. However, I am confused when to decrypt the images and how to determine which encrypted byte array belongs to a particular image. I want to use 2d byte array for this. Anybody having any ideas, on how I could do this?
