Among the Spartans, the scytale, also known under the name stick of Plutarch, was a wooden stick used for reading or writing an encrypted dispatch. It consisted of a polygonal rod or cylinder, around which was wrapped a piece of parchment. It is worth noting that transposition remains an important component of modern cryptographic algorithms due to its tremendous efficiency. The cipher had two metal disks that spun on the same axis. Sample Cryptogram The first recorded use of the scytale cipher was by the Spartans and the ancient Greeks who used it to transport battle information between generals. It takes as input a message, and apply to every letter a particular shift. Most of the credits goes to the wonderful go.crypto library. It can easily be solved with the Caesar Cipher Tool. The message is written along the cylinder, one letter per band, and when the end is reached, go to a new line. The block size can be considered as the length of the message parchment when wrapped around the rod. Encryption can be traced back to the hieroglyphics of ancient Egypt around 3000 B.C. They wound a belt on an angle around a rod so that its edges barely touched. Scytale Cipher Encryption. Scytale, Wikimedia Commons . It uses a stick called scytale . Then they wrote the message along the length of the rod on the belt. Usage. Installation. Introduction . This cipher is not rewritten into blocks for simplification because then, the cipher would not work.
