🇫🇷🚨 FRANCE BANS SOCIAL MEDIA FOR U15s → EVERYONE TO VERIFY THEIR AGE.
“For four months, all of us in France will have to prove our age,” said digital minister, Anne Le Hénanff 😡
What this means if you're in France → you'll need to user your ID card, France Connect, or facial recognition (selfie) to log in.
🚩 What’s sold as “online safety” means #surveillance via IDs checks or face scans. 🚩
We must fight against age verification - or the free web dies!

Here's a script using our PQCrypto 2008 software to decode the 2^255 size from tii_decoding_challenge in <1 sec on 1 core: cr.yp.to/2026/20260722-break… When TII announced its fake sizes in 2023, I said they had omitted "one of the central defenses in McEliece": web.archive.org/web/20260616…

The Crypto Forum Research Group (CFRG, part of the @inretafo), is holding a last call for two documents on hybrid KEMs: a mechanism that lets you safely combine post-quantum and classical algorithms into a single construction.

I've been involved with ISO/IEC JTC1 SC27 WG2 discussions about Simon/Speck, Kuznyechik, and QKD (and some more). This is nothing in comparison to the IETF TLS mailing list.
Somewhat behind schedule, but the Classic McEliece standard is finally out.

One interesting aspect of web.archive.org/web/20260622… is the demand that federal contractors (starting mid-2027) label "the use of non-FIPS approved algorithms" as a "vulnerability". The 1990s version of this would be telling contractors to label RSA above 512 as a "vulnerability".

The EU has a survey open on the QKD network EuroQCI, asking how they should invest their money. I've sent them some idea. (hint: replace by PQC).
You can also still contribute your input. Not sure how much longer this will stay up:
