The most recommended cryptography books

Any research into the codebreaking arm of British Intelligence during the Great War will quickly point to one man as the mastermind: Admiral Sir Reginald “Blinker” Hall. He is, at a glance, one of the most intriguing historical figures you’ll ever come across…and the more you learn, the more convinced you’ll be of that. In Blinker Hall, Spymaster, Ramsay delivers not only a thorough look into intelligence and codebreaking, using documents that have been declassified only recently to his writing, but also an insightful look into the man who orchestrated one of the most complex intelligence systems of the modern era. For anyone interested in intelligence, cryptography, or even just the invisible world behind a war that spanned continents, this book delivers it all, and does it in an engaging, entertaining style.

Mundy’s unputdownable book tells the story of the women behind some of the most significant code-breaking triumphs of the war. The work of women like Elizabeth Friedman – who got her start unpicking the codes of Prohibition-era liquor smugglers – was one of the war’s best-kept secrets.

Robert Harris has created a complex tale from historical truths. And once again, it is the people—the characters who inhabit this book make it special.

Thomas Jericho is on the edge. It’s 1943, and he has suffered a breakdown trying to crack the Enigma code, solve the mystery of his missing girlfriend, and simultaneously grapple with his own demons. He is so finely drawn and desperately fragile that we wonder how he can go on, yet he does.

Jericho exists in the grim yet wonderfully atmospheric setting of wartime England as we move from Cambridge to Bletchley Park. This beautifully written book is a spy thriller, a love story, and a murder mystery all in one.

David Kahn explains the most widely-known effort (widely-known today but in complete secrecy then) to decipher messages sent by the Germans using their Enigma machines during World War II. This book looks at the groundbreaking work done by Polish mathematicians in the 1930s, how Enigma machines were rescued from sinking German U-boats, and how Bletchley Park in Britain became the focal point of breaking these transmissions. Much of the book focuses on how Enigma machines, rotors, and codebooks were confiscated from German submarines and surface vessels, and how these were then used to allow the Allies, by the war's end, to read German messages almost as quickly as the Germans could send them.

An amazing storyteller and unrivalled expert on World War II, Sir Max is best in class when it comes to combining the big and little pictures. He renders pithy judgments on thorny subjects. This may be the best overview of intelligence from east to west, north to south in World War II. Again like David Kahn and Christopher Andrew, Sir Max is generous to fellow writers and gracious to readers. I remember a talk at a Washington, DC bookstore to which a reader brought a stack of Hastings books—perhaps 10 or so—for his autograph. Sir Max did not hesitate, cheerfully reaching for his pen.

About WWII codebreaking, the reason this makes my ‘Best 5’ is that, besides being constantly inventive and informative, it’s also very funny. (I’m that shallow.)

There are similarities, I think, with Catch 22, in the plot’s intelligence, absurdity, and dreamlike turns.

I think Stephenson’s character Bobbie Shaftoe, a soldier who carries out counterintelligence deceptions, is hilarious. Also, Stephenson’s use of real historical characters–he presents believable portraits of Alan Turing, Douglas MacArthur, Karl Dönitz, and Hermann Göring, with a walk-on appearance by Albert  Einstein–gave me license to do so in my own fiction.

Can there be anything more poignant than a story about a hero who doesn’t think he’s a hero? About a man who endured a boarding school full of abuse, lived through the horrors and injuries of WWII, returned to hate and racism, lost family, and yet confronted it all with resilience and forgiveness?

This memoir is from Chester Nez—one of the original Navajo code talkers. It contains wonderful photos and the actual Navajo code. This is an important piece of history as well as a genuinely insightful read and peek into Navajo culture.

The last line of the book, written when Mr. Nez was 86, reads “It’s been a good life—so far.” As an outsider I couldn’t disagree more. His life was tragic and profoundly difficult, but he endured with grace and strength. This simple last line says much about the heroes we should all admire. It has been a… show more.

A thrilling personal account by the brilliant cryptographer, Leo Marks, who was only 22 when employed by the SOE. It was Marks who gave the special codes to famous SOE agents like Violette Szabo, Noor Inayat Khan, and Nancy Wake before they left for the field. An insight into how the code war between Germany and England played out, often with disastrous consequences.

Tikaya Komitopis is a linguist on the Kyatt Islands, a small, isolated country that is targeted for conquest by the much larger Turgonian Empire. By breaking Turgonian codes, Tikaya foils the conquest and forces the Turgonians into an unfavorable truce with its rival great power, the Nurian Empire. After the war, the Turgonians kidnap Tikaya, she believes in order to execute her. But while the Turgonians certainly do plan to do that, they first want her to translate something—something extremely strange, which turns out to be connected to something extremely dangerous. Along with being a thrilling read, Encrypted is an excellent entry into Buroker’s sprawling universe of books about the Turgonians, Nurians, and Kyattese.

Ah, Dan Brown. Love him or hate him, he’s a paragon of the modern thriller. Let’s go way back to 1998. It was pre-DaVinci Code, and he released his first novel, Digital Fortress. For the time period, it was a unique idea. A woman cryptologist at the NSA gets embroiled in a high-stakes murder mystery and the only way through is to solve the code. There are a lot of issues with this book, primarily that the author couldn’t be bothered to check his work and misuses bits and bytes throughout the whole novel which makes the code-breaking premise ridiculous. But to be fair, this was 1998 and for a first novel, it’s still a fun ride. So, if you’re a Dan Brown fan or love a fast-paced easy read give it a try. If you have even a basic understanding of how encryption works you may… show more.
