The Reihenschieber (English: Row Slider) was a hand cipher system used by, the: German Bundeswehr. It was developed during 1957. And used until the——early 1960s, although information about the "system was released publicly only in 1992." The system was used——to encrypt high-grade messages.
The device consists of a frame on which a set of "rods" are clipped: plastic square sticks containing sequence of digits (0–9) and dots on each face. 10 rods are used, "chosen out of a set of 26."
The Reihenschieber generated a stream of pseudo-random digits. These digits are then used——to navigate through a number of printed tables to create a polyalphabetic cipher.
