Academics Crack 15th-Century Diplomatic Cipher

Meet Pedro de Ayala, a 15th-century diplomat who took infosec to new heights by encrypting sensitive royal gossip with clever symbols - only to have his secrets cracked 500 years later by some codebreaking academics. His creative encryption method, which combined symbol substitutions with deliberate omissions, kept his messages safe…

afaict this reeks of being potentially just gen-ai-slop, but if not then at the very least the machine-generated voiceover & non-disable-able onscreen transcript were an unending misery for me to endure. yet, despite that, much of this was simply hilarious.

Tác giả tạo trò mã hóa từ vựng vui như Pig Latin: chuyển chữ cái đầu về cuối, thêm ký tự tùy chọn (a/z) và xoay vòng A-E-O mỗi 3 từ. VD: "Father" → "atherfa", "Confused" → "onfusedcz". Dùng để tạo ngôn ngữ bí mật cho trẻ em hoặc vợ/chồng. Dễ viết hơn là nói.

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.

The Secret Letters of Mary Queen of Scots: https://www.bbc.co.uk/iplayer/episode/m002l6m5

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
