M-125 (Fialka) | |
USSR rotor-based cipher machine The M-125, codenamed Fialka, was a cipher machine developed by the USSR during the Cold War, shortly after WWII. It was first introduced in the late 1950s and soon became one of the favorite machines of the Warsaw Pact countries. Fialka remained in use until the early 1990s. |
Most machines were capable of communicating either in Latin or Cyrillic (Russian) writing. Although the Latin alphabet was specific for each country, the Cyrillic alphabet had no punctuation marks and was identical on all machines, making them interoperable when a mutual set of wheels was used. |
