 This software is an accurate simulation of the
Hagelin BC-52, one of the most famous Cold War era crypto
machines. After the success of the C-38 and M-209 as
tactical cipher devices, Hagelin developed a cipher
machine for high level military and diplomatic
encryption. In 1952 Hagelin Cryptos (Crypto AG)
introduced the C-52 and, as Devours and Kruh wrote,
'caused ripples throughout the cryptanalytic community'.
The C-52 raised the security of pin-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 were 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. This very realistic Hagelin BC-52 Cipher Machine Simulator enables you to encipher and decipher messages and apply the key settings as you would with an actual machine. You can select between the C-52 and CX-52 model and customize the machine in various ways. There's also a formatted clipboard and an Autotyping function. The program includes a detailed help file containing the enciphering procedures, how to set the machine and all technical details (Click the screenshot to enlarge the picture). Runs on all Windows™ versions and with WINE on Linux or Parallels Desktop on MAC. All feedback or comments are most welcome by e-mail or by visiting the Guestbook. Download the simulator
