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 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 remaind 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
