WEBA cipher disc is a mechanical tool made up of 2 dials (1 inner disc and 1 outer disc) making it possible to represent a mono-alphabetic substitution by rotating the discs relative to each other. The alignment of the boxes thus obtained indicates the correspondence of …
Alberti's Wheel Cipher Disk - Online Decoder, Encoder, Translator
WEBThe Alberti cipher is a polyalphabetic cipher system that uses two mobile concentric disks which can rotate. How to encrypt using Alberti cipher? Encryption uses a disk with two alphabets, one fixed (stabilis) one moving (mobilis). By rotating a disk, it shifts an alphabet to the next letter.

The Alberti Cipher - Computer Science
WEBAlberti designed his cipher technique with courtesans and diplomats in mind. The inner disc had a randomized uppercase Latin alphabet, which is the English alphabet minus u, w, and j, and with et (probably meaning '&').
WEBThe cipher disk came into large· scale use in the United States for the first time in the Civil War. The Federals' Chief Signal Officer patented a version of it, very similar to the original Italian disk, for use in flag signaling.
