The science of cryptology is made up of two halves. Cryptography is the study of how
to create secure systems for communications. Cryptanalysis is the study of how to
break those systems. The conflict between these two halves of cryptology is the story
of secret writing. For over two thousand years governments, armies, and now individuals
have wanted to protect their messages from the "enemy". This desire to communicate
securely and secretly has resulted in the creation of numerous and increasingly complicated
systems to protect one's messages. On the other hand, for every new system to protect
messages there is a cryptanalyst creating a new technique to break that system. With
the advent of computers the cryptographer seems to finally have the upper hand. New
mathematically based cryptographic algorithms that use computers for encryption and
decryption are so secure that brute-force techniques seem to be the only way to break
them so far. This work traces the history of the conflict between cryptographer and
cryptanalyst, explores in some depth the algorithms created to protect messages, and
suggests where the field is going in the future
