Cryptology is the study of secret communications. There are two primary

branches of study: cryptography and cryptanalysis. Cryptography is the

study of developing secret communications. Cryptanalysis is the study of

breaking secret communications.

Of secret communications, there are two primary branches: cryptographic

systems and steganographic systems. Cryptographic systems seek to secret

the meaning of information conveyed, whereas steganographic systems

seek to secret the existence of the information itself.

Cryptogaphic systems are composed of two branches: ciphers and codes.

Cipher systems encrypt single (or groups) of letters at a time whereas code

systems encrypt whole words, phrases, or sentences at a time. The primary

difference here is that code systems operate on the level of meaning.

The result of encrypting a message [clear text] results in ciphertext.
