Cryptography has been used since ancient times to send hidden messages. The MIS-X, the Enigma Machine, the Vigenere Cipher, and the Spartan Scytale are examples from history.

But it is always there, thanks to the scholars and codebreakers who worked through the centuries to turn cryptography into what it is today.
