A broad and lucid survey of cryptographic strategies. These range from steganography and substitution ciphers to second factor authentication and other recent trends in cybersecurity. She also provides plenty of variously coded examples for readers to decipher as practice, capped by a final challenge to go back and find the clues to a secret message that have been distributed throughout. Her detailed description of how the German Enigma machine worked (and was hacked by the Bletchley Park group in World War II) is indeed “fascinating,” as are the close analyses of still-unsolved messages such as the modern Kryptos inscription outside CIA headquarters.
