The Kryha Liliput is a very rare cipher machine in pocket-watch format. The machine consisted of two concentric rings, each featuring an alphabet and numbers. The user would operate it by pushing a lever to step the inner ring a random number of places against the outer ring, thereby changing the relationship between the two.
Although Kryha’s devices were a commercial success, they were cryptographically weak as the period lengths of the codes were generally quite short.
The Kryha Liliput was cryptographically compatible with its “big sister”, the Kryha Standard.
