Cryptographical rotor machine
WebRotor Machines In cryptography, a rotor machine is an electro-mechanical stream cipher device used for encrypting and decrypting messages. In the 1920s, various mechanical encryption devices were invented to automate the process of encryption. Most were based on the concept of a rotor, a mechanical wheel wired to perform a general substitution ... WebMay 11, 2024 · Around 1500 BC, a scribe from Mesopotamia used cryptography on a clay tablet to protect his recipe for a pottery glaze. The ancient Spartans encrypted messages by writing on parchment stretched around a cylinder. The recipient had to know the size of the cylinder to wrap the parchment around it and read the code.
