The Soviet efforts to reverse engineer the Enigma machine resulted in the M-125 Fialka cipher machine. This machine used ten rotors, with adjacent rotors turning in opposite directions.

The integrated rotor turning system allows for easier servicing, using a two-button pendant to hydraulically position the rotor. Cat System K milling rotors are available with spacings of 8 mm, 15 mm, ...

Although known notoriously as the uncrackable cryptography tool used by Germany during World War II, the Enigma Machine was eventually undone by the father of artificial intelligence, Alan Turing ...

After a long period of wear and after a number of turnings, a rotor can become so thin that it does not meet the manufacturer’s specifications for structural soundness. As long as the overall ...

A team of divers found this rusted—but still recognizable—Enigma cipher machine at the bottom of the Baltic Sea. The Nazis used the device to encode secret military messages during WWII. World ...
