Okay, if you suspect an image contains a wallet, place the image into the app, then enter the password to decrypt the AES data.

It uses a mixture of cryptography (encrypting) and steganography (hiding). So if you suspect something, you now have to know the password to see if you'll get anywhere.

I guess my aim is to move the target from just wallet.dat files to everything such as: pictures, audio files, movies, videos! anything could contain a private key.
