chronicling the history of cryptography from ancient Egypt to the time of its writing. The United States government attempted to have the book altered before publication, and it succeeded in part. https://en.wikipedia.org/wiki/The_Codebreakers

The author passionately tries to make a potentially dull story exciting…and occasionally pulls it off. The final chapter summarizes it all, but "the devil is in the details", inasmuch as the Enigma code was broken by luck, stupidity and intuition--with a little mathematical know-how thrown in for seasoning. Actually, the code was not "broken", only illuminated occasionally; knowing how the enigma machine was built and how it functioned will only take you so far--it's knowing the initial "key" that provided any clear solutions. And the "key" changed often enough to make life miserable for the British code breakers. The stories of the people--on both sides of the equation--provide a lot of the entertainment in the book, along with the many plots and plans to steal or hide information (Ian Fleming’s efforts on the war front were original and definitely entertaining); and the tensions & fears & deaths--on both sides--do help the narrative move along. But it quickly becomes clear that the invulnerable Enigma code was broken and fixed and broken again and again throughout the entire war.

Meanwhile, Kahn does not let us forget how hard the Nazis were working on breaking our codes. In the end, it’s as Tartakower said: “The winner of the game is the player who makes the next-to-last mistake.”

Well written and eminitely readable book. The German navel enigma was more protected cryptographically speaking, than the army/air force enigma, and thus required greater effort to break it. The 'breaks' came in the way of seizures of document keys from captured German weather ships and U-boats. The many factors leading to the Allies ultimate success in the North Atlantic is the basis of this book.

A very comprehensive history of hidden writing, codes, ciphers and other such things. It goes pretty well into depth with how it describes ancient codes and ciphers, how new ones were made and how they were then broken.

It doesn't cover internet security or anything, since this edition of this book was published in 1967. So it is still in the midst of the Cold War. Interestingly, most code breaking was done by linguists and language experts, but that eventually turned into mathematicians.

It doesn't talk about Alan Turing, since at the time of this book being published, it was classified, or at least I think it was.

Anyway, a wonderful tome on how people tried to keep their messages secret.
