The Code Book by Simon Singh, published in 1999, is a comprehensive history of cryptography, tracing the science of secret communication from ancient Greece to the modern digital age. Singh charts the "intellectual arms race" between codemakers and codebreakers, illustrating how their competition has shaped historical events like the execution of Mary, Queen of Scots, and the outcome of World War II.

This section marks a pivotal shift from classical to modern cryptography. The central problem of secrecy had always been the same: how could two people (whom Singh playfully dubs "Alice" and "Bob") exchange a secret key without it being intercepted by their enemy ("Eve")? Singh explains the ingenious solution: public-key cryptography. He describes the groundbreaking work of Whitfield Diffie and Martin Hellman, and later, the RSA algorithm (named for its inventors Rivest, Shamir, and Adleman). This revolutionary idea allowed someone to publish an "open" key for anyone to encode a message, while the recipient alone held a separate, "private" key to decode it, effectively solving the age-old problem of key distribution and laying the foundation for secure Internet commerce.
Moving beyond artificial ciphers, this chapter explores the challenges posed by unknown languages. Singh discusses the decipherment of Egyptian hieroglyphs, the race between Thomas Young and Jean-François Champollion to unlock the secrets of the Rosetta Stone, and the fascinating story of the Navajo Code Talkers, whose unwritten language served as an unbreakable code during World War II. This chapter also touches on the decryption of Linear B, the ancient script of Minoan Crete, demonstrating that cryptanalysis extends far beyond military applications.
