Just now learning that the solution to #Kryptos K4 was sold at auction this month for almost a million USD. Buyer anonymous; my tinfoil hat says probably the CIA, since their sculpture loses a ton of cultural value if K4 is cracked. Two people also found the plaintext in some papers Sanborn accidentally donated to the Smithsonian. But as yet the solution remains secret.

Exciting times for us #cryptography weirdos.

35 years ago, Jim Sanborn presented the cryptographic sculpture Kryptos to the Central Intelligence Agency in Langley, Virginia. Made from copper, granite, quartz and petrified wood, it has four sections, each of which holds a message in code. Over the years, three of the sections have been solved — by CIA code breakers, a California computer scientist, and the National Security Agency. Now, 79-year-old Sanborn says he's going to auction off the solution to the final message, with the company arranging the sale estimating a winning bid between $300,000 and $500,000. Here's @newyorktimes's story on why he's doing it now, and what he hopes the winning bidder will do with the secret.

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

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.
