Codebreaking

“Codebreaking: A Practical Guide is quite the best book on codebreaking I have read: clear, engaging, and fun. A must for would-be recruits to GCHQ and the NSA!”
—Sir Dermot Turing, author of Prof, the biography of his uncle, Alan Turing

—Mike Godwin, creator of Godwin’s law and former general counsel for the Wikimedia Foundation

“A compendium of historical cryptography. Approachable, accessible, this book brings back the joy I felt when I first read about these things as a kid.”
—Phil Zimmermann, creator of PGP encryption and inductee into the Internet Hall of Fame

“One of the most helpful guides outside the NSA to cracking ciphers. But even if you don’t become a codebreaker, this book is full of fascinating crypto lore.”
—Steven Levy, New York Times best-selling author of Crypto, Hackers, and Facebook: The Inside Story

“Another kind of Applied Cryptography.”
—Whitfield Diffie, Turing Laureate and creator of public-key cryptography

“Cryptography? Ciphers? I thought this would be an easy book to put down. I was very wrong.”
