TL;DR: This article reviews both published and archival material, and provides some examples of actual use and cryptanalysis from the period immediately before and during the Second World War.
Abstract: The Kryha machine was introduced in 1924 and continued to be marketed into the 1950s. The cryptologic literature surveyed for this article includes descriptions of various models of the machine and methods of attacking it, but relatively little has been written about its operational use. This article reviews both published and archival material, and provides some examples of actual use and cryptanalysis from the period immediately before and during the Second World War.

TL;DR: It is the tragedy of Alexander von Kryha that he made a huge effort in marketing his machines, but did not realize that he was dealing with one of the poorest designs ever.
Abstract: Alexander von Kryha (1891-1955) dedicated at least 15 years of his life to encryption machines of his own development. His machines competed with the Enigma in the 1920s and with Hagelin's machines in the 1950s, but they were much too weak cryptographically to succeed. It is the tragedy of Alexander von Kryha that he made a huge effort in marketing his machines, but did not realize that he was dealing with one of the poorest designs ever. In 1955 Kryha committed suicide, while his company went bankrupt.

TL;DR: In the early part of this century, a mechanical “ciphering machine” was invented by a German engineer, Alexander von Kryha of Berlin, which received both the State Prize from the Prussian Ministry of the Interior and a Diploma from Dr. Konrad Adenauer at the Internaltional Press Exhibition (Cologne).
Abstract: In the early part of this century, a mechanical “ciphering machine” was invented by a German engineer, Alexander von Kryha of Berlin. The Kryha-Ciphering-Machine received both the State Prize from the Prussian Ministry of the Interior at the 1926 Police Fair (Berlin) and a Diploma in 1928 from Dr. Konrad Adenauer at the Internaltional Press Exhibition (Cologne). George Hamel, who was to become famous for his work in set theory, published an analysis in 1927 of the size of the key space, which was quoted extensively by “Internationale Kryha-Maschinen-Gelleschaft” (Hamburg) to infer the unbreakability of the Kryha machines.
