This one-stop practical guide will show you how to make and break codes. It comes in a handy two-colour format, and includes fascinating historical examples as well as practical tips.
Why do we use codes? Why do we need them? From the moment we began communicating, we have looked for ways to make our messages concise and clear; but with the advent of wars and trading, it has been necessary to find ways to keep some of that communication secret.
This book touches on everything from the smoke signals used by the Native Americans to the encryption devices used by government agencies and the military. As well as covering the history of the development of codes and ciphers, it also includes practical information and advice on how to make codes (whether by pencil and paper, or by computer) and, more importantly, how to break them!
Topics covered include: Native American smoke signals; masonic signals; flags and semaphore; morse code; Braille; ASCII computer language; letter substitution; computer algorithms; the role of codes and codebreaking through history, including the American Civil War and the First and Second World Wars.
