The Pike cipher, also known as the Pike's cipher or Pike's cipher wheel, is a form of a substitution cipher that utilizes a device or a tool resembling a wheel or a disk to encrypt and decrypt messages. The design involves a set of concentric discs, each with letters or symbols arranged around its edge, which can be rotated relative to one another to create a varying substitution for each letter.
