Julius Caesar created his own code, the Caesar Cipher, to protect his messages. Mary Queen of Scots employed a code in her attempt to dethrone Elizabeth I. The Enigma machine was manufactured for the automatic encryption of messages during the Second World War. And the battle rages on. How private are your e-mail communications?
