This is only a proof of concept cracking of a 22 bit RSA key. However it shows that the cracking of cryptographic algorithms that we are currently using require advances in technology rather than in theory or basic science. I suspect that the time we have before our current banking security is useless is a few decades, but there time before national agencies can crack messages protected by these algorithms a lot less

Enigma Myth Deciphered. Codebreakers, Commanders and Politicians by Marek Grajek, 2024

This unique new volume analyses source documents both previously known and recently declassified, generating an extremely broad and original synthesis about Enigma.

The author uses his experience as a cryptologist to fill in gaps in the sources or to correct misguided interpretations, also adding the passion of a journalist, drawing a vivid picture of the characters and the story. As a Pole, he presents this story through the lens of the fate of the Polish mathematicians who were the first to break the cipher as early as 1932 and laid the foundations for the subsequent Allied success.
The book’s coverage ranges from the mathematical foundations of codebreaking, through the complex fates of the people and organisations involved in the attacks on the Enigma ciphers, the impact of decrypts on the fate of the major campaigns of the Second World War, to the role that wartime cryptology and codebreakers played in the birth of digital civilisation. The Polish mathematicians’ story is presented in the full context of the struggle with the cipher, including the complex interplay between codebreakers, military commanders and politicians of the UK, US, Poland, France, and the Third Reich.
By looking at events through the eyes of a cryptologist rather than solely as a historian, the reader is given a glimpse into the backstage of the cryptologic workshop; a better understanding of the scale and nature of the challenges codebreakers faced; and insights into their responses to those challenges, as well as the emotions, dilemmas, disappointments, and triumphs involved.

"A lover of puzzles and crosswords while growing up in Pittsburgh during the Great Depression, Mrs. Parsons deciphered German military messages that had been created by an Enigma machine, a typewriter-size device with a keyboard wired to internal rotors, which generated millions of codes. Her efforts provided Allied forces with information critical to evading, attacking and sinking enemy submarines."

One of the last of Bletchley Park's quiet heroes, Betty Webb, dies at 101.

Betty Webb MBE, one of the team who worked at the code-breaking Bletchley Park facility during the Second World War, has died at the age of 101.

For 30 years she never told anyone about her wartime experiences and it wasn't until the 1970s that she was informed that the prohibition on discussing Bletchley had been lifted.

Weekly output: Musk digitally deleting USAID, Arm vs. Qualcomm, U.K. vs. Apple, 8K TV, Bletchley Park

One of this week’s published stories began with reporting weeks ago; another began with notes and photos taken months ago.

2/3/2025: Musk’s Minions Deleting Digital Presence of US International Development Agency, PCMag

I could not just write about the weird digital erasure Elon Musk and his goons have been inflicting on the online presence of the U.S. Agency for International Development without reminding readers of three important bits of context: USAID does good and useful work (as vouched for in that quote from Georgetown University government-department chair Anthony Arend, four of whose classes I took as an undergrad 35-plus years ago); USAID constituted all of .4% of the federal budget in fiscal year 2024; Elon Musk’s tweets show no sign of him having any interest in the agency until January.

2/6/2025: Arm Drops Effort to Cancel Qualcomm’s Chip-Licensing Deal, PCMag

If you were considering buying a Windows laptop with one of Qualcomm’s power-efficient Snapdragon X processors, this should rank as very good news.

2/7/2025: Report: UK Orders Apple to Disable E2E Encryption on iCloud Backups Worldwide, PCMag

Writing up the Washington Post’s scoop about this dangerous demand by the U.K.’s Home Office gave me a crash course in looking up and citing legislation on Parliament’s Web site–without which I would have been writing about the Investigatory Powers Act without pointing people to the text of that 2016 statute and its 2024 amendments.

2/8/2025: In 2025, the Picture for 8K TVs (Still) Isn’t Looking Too Bright or Sharp, PCMag

I originally had delusions of writing this piece from CES with a Las Vegas dateline, but the weeks since then allowed me to get some additional numbers from the Consumer Technology Association and quiz another analyst as well as the head of the 8K Association.

2/9/2025: To See Codebreaking At Its Most Metal, Visit Bletchley Park, PCMag

Some of you may remember my writing a piece about Bletchley Park for the long-gone information-security publication The Parallax in 2018. I decided to revisit this museum of WWII codebreaking when my trip to London in October for Uber’s Go-Get Zero event (on Uber’s dime) left me with an afternoon free, and I’m glad I did because I was able to check out one exhibit that I’d had to skip earlier and see a few exhibits they’d added since then.

Associated Press: UK spy agency releases annual Christmas card puzzle to uncover future codebreakers. “GCHQ, Britain’s electronic and cyber-intelligence agency, on Wednesday published its annual Christmas Challenge – a seasonal greeting card that doubles as a set of fiendishly difficult puzzles designed to excite young minds about solving cyphers and unearthing clues.”

Code Warriors: NSA's Codebreakers and the Secret Intelligence War Against the Soviet Union by Stephen Budiansky, 2016

Stephen Budiansky—a longtime expert in cryptology—tells the fascinating story of how NSA came to be, from its roots in World War II through the fall of the Berlin Wall. Along the way, he guides us through the fascinating challenges faced by cryptanalysts, and how they broke some of the most complicated codes of the 20th c.

A sweeping, in-depth history of NSA.
The National Security Agency was born out of the legendary codebreaking programs of World War II that cracked the famed Enigma machine and other German and Japanese codes, thereby turning the tide of Allied victory. In the postwar years, as the United States developed a new enemy in the Soviet Union, our intelligence community found itself targeting not soldiers on the battlefield, but suspected spies, foreign leaders, and even American citizens. Throughout the second half of the twentieth century, NSA played a vital, often fraught and controversial role in the major events of the Cold War, from the Korean War to the Cuban Missile Crisis to Vietnam and beyond.

With access to new documents, Budiansky shows where the agency succeeded and failed during the Cold War, but his account also offers crucial perspective for assessing NSA today in the wake of the Edward Snowden revelations. Budiansky shows how NSA’s obsession with recording every bit of data and decoding every signal is far from a new development; throughout its history the depth and breadth of the agency’s reach has resulted in both remarkable successes and destructive failures.
Featuring a series of appendixes that explain the technical details of Soviet codes and how they were broken, this is a rich and riveting history of the underbelly of the Cold War, and an essential and timely read for all who seek to understand the origins of the modern NSA.

When the Polish code breakers had found a German enigma key, it was sent to the British encrypted using... an enigma machine!
