Description
Excerpted from the website:
- What is Cryptography?
- Cryptography is the science of secure communications, formed from thr Greek words kryptós meaning "hidden" and lógos, meaning "word". The first recorded use of cryptography was by the Spartans who (as early as 400 BC) employed a cipher device called a "scytale" to send secret communications between military commanders. The scytale consisted of a tapered baton around which was wrapped a piece of parchment inscribed with the message. Once unwrapped the parchment appeared to contain an incomprehensible set of letters, however when wrapped around another baton of identical size the original text appears.
