US M-209 Simulator 3.0
|
On this
page you can download the freeware Award Winning M-209 cipher
machine simulation. This program is an accurate simulation of the
M-209 Cipher Machine, used by the US Military during World War 2.
The M-209, the American licensed version of the Hagelin C-38, was
a portable hand operated cipher machine for tactical messages. It
had the size of a lunchbox and presented a brilliant mechanical
design, developed by the Swedish cryptographer Boris Hagelin.
This simulator, fully compatible with the original cipher
machine, enables realistic operation with rotating wheels,
setting of wheel pins and drum lugs, combined with authentic
graphics. The program comes with a very complete helpfile,
containing the manual, the enciphering procedures from the US
military and all technical details on the machine. There's also a
picture gallery. Complete with formatted clipboard and Autotyping
function. With this program you will be able to work with the
M-209 and examine how it works and how it was operated. This is a
true reference to the M-209, and an educational must! On the
bottom of this page you can find some screenshots, taken from the
program.
Runs under Windows™ 98/ME/2000/XP/Vista
Now with practical drop-down menu and pdf help file
with enciphering procedures and technical details.
