Generate CAP codes using an emulated banking card and CAP calculator, to test against real gadgets or for testing authentication servers.
This application derives session keys from the card master key, following the algorithm described in EMV 4.1, Book 2, Part III, Annex A1.3. It then uses this key to generate authentication codes following the Chip Authentication Program (CAP) specification, when given the input to the disconnected card reader and the internal configuration of the card.
