USSR Cipher Machines
Like the USA, the former USSR (now Russia) has a long cryptographic history. Over the years, they produced a wide range of cipher machines that were used by the Russians themselves and by their allies of the former Warsaw Pact states, such as the DDR, Czechoslovakia, Hungary, Romania and Yugoslavia.

Unfortunately though, not much is known about the cipher machines of the USSR as most of them were produced at the height of the Cold War, when East and West were separated by the tightly closed Iron Curtain.
  

After the fall of the Berlin Wall in 1989 and the collapse of the Soviet Union a few years later, most machines were withdrawn by the Russians and have subsequently been destroyed. Only very few machines have escaped the sledge hammer. USSR machines featured on this website:
 
M-125 (Fialka) wheel-based cipher machine Fialka M-130 (Koralle) meteorologic cipher machine M-130 Moscow=Washington Hotline Hotline

 
M-125 Fialka
The M-125 (codename: Fialka) was one of the most beautiful and compact electro-mechanical cipher machines produced by the USSR during the Cold War. It was used by most Warsaw Pact countries, including Russia itself.

It has a built-in printer, paper puncher, paper tape reader and a 10-wheel cipher machine with irregular wheel stepping.

M-130 Koralle
The M-130 (codename: Koralle) was used for the encrypted distribution of weather reports between the former Warsaw Pact countries. It was intended to be used in case a war broke out between East and West.

As the weather reports were further distributed via other cipher machines, the enemy could exploit them as a possible crib. For that reason, the meteorological data had to be encrypted.
