The hidden history of code-breaking : the secret world of cyphers, uncrackable codes, and elusive encryptions
(Book - Regular Print)

A fascinating exploration of the uncrackable codes and secret cyphers that helped win wars, spark revolutions and change the faces of nations.

There have been secret codes since before the Old Testament. Almost as soon as writing was invented, so too were the devious means to hide messages and keep them under the wraps of secrecy. McKay takes readers on a fascinating exploration of the uncrackable codes and secret cyphers that helped win wars, spark revolutions and change the faces of nations. From the temples of Ancient Greece to the court of Elizabeth I; from antique manuscripts whose codes might hold prophecies of doom to the modern realm of quantum mechanics, we will see how a few concealed words could help to win wars, spark revolutions and even change the faces of great nations. -- adapted from jacket
