Communication is key. And sometimes it has to be keyed so that others can't understand what is being said.
Filled with fascinating testimony from cryptologists and historians, CODES ventures from the age of hieroglyphs--only deciphered after the discovery of the Rosetta Stone in the 19th century--to today, when computers put powerful encrypting technology within reach of virtually everyone. Hands-on demonstrations of inventions and techniques like cipher discs and polyalphabetic encryption show how messages have been protected in the past, and we'll examine some of the pivotal moments in the history of encryption, from Caesar's use of coded messages to the capture of a German Enigma machine during World War II.
In war and peace, CODES have held the keys to the fate of nations and people, and the effort to create and decipher them is a fascinating blend of science, engineering, and psychology.
