21Alberti cipher disk — The Alberti cipher disk, also called formula, is a cipher disc which was described by Leon Battista Alberti in his treatise De Cifris of 1467. The device embodies the first example of polyalphabetic substitution with mixed alphabets and variable… …
22C-36 (cipher machine) — The C 35 and C 36 were cipher machines designed by Swedish cryptographer Boris Hagelin in the 1930s. These were the first of Hagelin s cipher machines to feature the pin and lug mechanism. A later machine in the same series, the M 209, was widely …
23C-52 (cipher machine) — The (Hagelin) C 52 and CX 52 were cipher machines manufactured by Crypto AG starting 1951/1952. These pin and lug type cipher machines were advanced successors of the C 38/M 209. The machine measures 8 1/2in times; 5 3/8in times; 4 3/8in. The… …
