I'm a little late to the game on this announcement, but #Python 3.14 is dropping #PGP for sigstore.
Another nail in the coffin for PGP.

Jim Sanborn Is Auctioning Off the Solution to Part Four of the #Kryptos Sculpture
Schneier on Security · Jim Sanborn Is Auctioning Off the Solution to Part Four of the Kryptos Sculpture - Schneier on SecurityWell, this is interesting: The auction, which will include other items related to cryptology, will be held Nov. 20. RR Auction, the company arranging the sale, estimates a winning bid between $300,000 and $500,000. Along with the original handwritten plain text of K4 and other papers related to the coding, Mr. Sanborn will also be providing a 12-by-18-inch copper plate that has three lines of alphabetic characters cut through with a jigsaw, which he calls “my proof-of-concept piece” and which he kept on a table for inspiration during the two years he and helpers hand-cut the letters for the project. The process was grueling, exacting and nerve wracking. “You could not make any mistake with 1,800 letters,” he said. “It could not be repaired.”...

This paper is SO good.
“Replication of Quantum Factorisation Records with an 8-bit Home Computer, an Abacus, and a Dog”
Today has been one long time-travel smear of MetaCTF challenges that included a *lot* of #cryptography (why do I enjoy this so much?), web exploitation, and #forensics (Navigating Windows Event Viewer is like surfing the web in the 90s).
My brain is an inanimate spherical-shaped lump of goo. I hope no one in this house needs anything from me for at least 12-16 hours.
A #cybersecurity warrior always has more to learn. Especially about the wizardry of #cryptography. https://cromwell-intl.com/cybersecurity/crypto/reading.html?s=mc

This was an important win and Apple deserves credit for pushing back.

I've been reading people's mail.
They are the letters of Abigail and John Adams from 1775, so historians tell me this OK?
John is *extremely* cautious in writing. Lots hints and promises to say more in person. This was wise, because a lot of the letters of the Continental Congress were intercepted by the British at the time.
This all makes me wonder what the state of #cryptography was in those days, and whether the Adams could have adopted any good encryption measures.

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.

Do #Apple folks out there at least know whether Messages (a.k.a. iMessage) on #iOS uses one of the above mentioned methods to provide end-to-end encryption of the content of push notifications (which in general contain portions of messages)? I know that the messages themselves are end-to-end encrypted, I'm specifically asking about the content of the notifications.
