A cipher disk is a device for encrypting and decrypting messages using two concentric circular plates with alphabets or numbers. Learn about its history, methods, variations, weaknesses and popular culture examples.
The 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 Cipher Disk. This simple device has a distinguished history. Ever since its first invention it has been repeatedly re-invented in forms only slightly different from the original. Its story shows that man has sought to put the wheel to use in secret communications wherever possible, even as he also does in mechanics.
Jefferson's wheel is a polyalphabetical cipher that uses a cylinder made of several vertical rotating wheels. Each of the 26 letters of the alphabet are randomly written on the edge of each wheel.
Cipher Disk Encryption Challenge. Create a simple shift cipher device to encrypt and decrypt secret messages.
At its core, the virtual Caesar Cipher Wheel is a simple yet powerful educational instrument. It comprises two concentric disks: an outer disk with the standard alphabet and an inner wheel that rotates to display a shifted alphabet sequence.
