Ciphered Riches: Cracking Codes That Guard Historical Treasures

A cryptography primer tailored to treasure hunters: simple substitution ciphers, polyalphabetic ciphers, advanced methods, and practical techniques for decoding maps and clues. Includes specific chapters on cracking historical pirate codes, cryptanalysis techniques, the psychology of code-making, and hands-on exercises. Treasure maps, dying declarations, and encoded journals have guarded fortunes for centuries—and the key is often a cipher within reach of a determined codebreaker. This book gives you the cryptographic toolkit to unlock messages that have stumped casual readers for generations, turning encoded scribbles into coordinates.
