Kahn's first book was The Codebreakers (1967), widely considered a definitive account of the history of cryptography, up to the early 1960s. In particular, the story of cryptography in World War II was still then effectively classified. The most recent edition, published in 1996, has an additional chapter surveying with less depth events and breakthroughs in cryptology since the first edition, such as the advent of public key cryptography and PGP. The Codebreakers was a finalist for the non-fiction Pulitzer prize in 1968.
