Cryptology
From Wikipedia, the free encyclopedia
Cryptology is an umbrella term for cryptography and cryptanalysis. Cryptology is usually taken to mean the study of mathematical, linguistic, and other coding patterns and histories. "Cryptography" is used in many English language publications in the field, as an equivalent 'highest order' term for the entire field. In several European languages cognate terms seem to follow the pattern given here. English, as is often the case, is more flexible (or confused, depending on taste). It certainly introduces a note of confusion in translating between languages in one camp and English.

Some famous uses of codes in cryptography have been by famous people throughout history. One of these people is Julius Caeser. Julius used to code his messages using the caeser cipher, a simple technique of designating a letter of plain text alphabet to a shifted alphabet.
e.g.
abcdefghijklmnopqrstuvwxyz
xyzabcdefghijklmnopqrstuvw
using this shifted alphabet your message could be "hello" which would be tranferred into code by using the letters under the first alphabet. Hello would then become Ebiil and therefore noone would able to read your message unless they knew the cipher.
