The word is derived from the Greek kryptos, meaning hidden.
The origin of cryptography is usually dated from about 2000
BC, with the Egyptian practice of hieroglyphics. These
consisted of complex pictograms, the full meaning of which
was only known to an elite few. The first known use of a modern
cipher was by Julius Caesar (100 BC to 44 BC), who did not
trust his messengers when communicating with his governors
and officers.
