Hagelin BC-52 Simulator

I just finished a new cipher machine simulator, the Hagelin BC-52. It's an accurate simulation of one of the most powerful and commercial successful machines of engineer Boris Hagelin. Hagelin developed this cipher machine for high level military and diplomatic encryption. In 1952 Hagelin Cryptos (Crypto AG) introduced the notorious C-52, raising the security of drum-and-lug devices to another level. The machine had 6 irregular moving pinwheels, selected from a set of 12, and the number of drum bars was extended to 32, of which 5 where also used to advance the wheels. When lugs and pins are selected carefully the C-52 provides even in this computer era a powerful encryption. The combination of C-52 and the keyboard, denoted B-52, was named BC-52. Within short time the BC-52 was purchased by more than 60 countries and remained popular until today. As usual, the simulator is available as freeware download on my website.
