Description
Codes, Ciphers and Secret Writing is a fascinating guide to the world of cryptography. This comprehensive book explains how to use various codes and methods of secret communication that have been used since ancient times.
From simple letter substitutions and transposition ciphers to more complex polyalphabetical ciphers and grid-based codes, Martin Gardner provides clear explanations and practical examples for breaking these codes. You'll also learn about codes that are keyed to everyday objects like typewriters and telephone dials, as well as invisible writing methods.
Using this book, you can tackle historically famous ciphers like the Playfair Cipher used by Australia in World War II, and experiment with a range of bizarre message sending methods, including the Dot Code, Knot Code, and Swizzle Code. Whether you're interested in cryptography, puzzles, or just want to learn more about secret communication, this book is an engaging and challenging read.
