WebMay 1, 2024 · Cryptography, at its most basic, is the science of using codes and ciphers to protect messages. Encryption is encoding messages with the intent of only allowing the intended recipient to understand the meaning of the message. It is a two way function (you need to be able to undo whatever scrambling you’ve done to the message). WebIn the early history of the United States, codes were widely used, as were book ciphers. Book ciphers approximate onetime keys if the book used is lost or unknown.
