UnrealKey is a tool for automatically finding the AES-256 decryption keys for Unreal Engine 4 encrypted pak files. Pass the path to a game's executable as an argument to UnrealKey.exe, and it will launch the game and attempt to detect the loading and decryption of encrypted pak files. If successful, the decryption key(s) will appear in the output, usually within a few seconds of launching the game.
