Cryptography is the science of using codes and ciphers to conceal information. Cryptology is the study of cryptography. Codes and ciphers are terms that are often used interchangeably, but they are distinctly different. A code replaces one piece of information for another entirely different piece of information where the meaning of both is known to both the sender and recipient. A common example of this may be using a phrase such as We have contact to mean We have found the thing we're looking for. A cipher, on the other hand, modified the information itself to obscure its meaning.

A timeline of cryptography through the middle ages may be found on the House Blue Heron Cryptography website[1].
