Watching trump fold on tariffs shouldn't surprise you. He folded to Russia before we even negotiated.

Sverige är ett av få EU-länder som inte redan infört EU-Alert, så detta är på tiden.

Just the fact that posts in Bsky by default (AFAIK) are sorted based on time (newest first), not by some AI that tries to give me what it deems most relevant, is reason enough to use it.

And being able to actually read comments, even if your are not logged in.

Governments identify dozens of Android apps bundled with spyware | TechCrunch The advisories say the spyware apps are used to target members of civil society who may oppose China’s state interests.

New, by @lorenzofb.bsky.social: A coalition of global governments have identified dozens of Android apps that are bundled with the prolific BadBazaar and Moonshine spyware strains, which they say are targeting civil society who oppose China's state interests.

fi-le.net fi-le.net, the Fiefdom of Files

This popped up on HN the other day, and it was one of the more fun “classical cryptography” posts I’ve seen in ages. Roughly speaking, someone discovered that AI models like Claude can decode the Caesar cipher, even when the “key” used is enormous. fi-le.net/byzantine/

Releases · openssl/openssl TLS/SSL and crypto library. Contribute to openssl/openssl development by creating an account on GitHub.

The upcoming release of OpenSSL (3.5.0) not only includes PQC agorithms ML-KEM, ML-DSA and SLH-DSA, it also makes the hybrid key kem schemes the preferred schemes. More PQC support in infrastructure we need. And once again a hybrid, not pure PQC solution.

Current status for cryptography in payment systems from the ICMC conference. We are still transitioning from DES to AES. And transition to PQC is basically around the corner.

Heatmap: Current State of PQC Standards and Adoption | Post-Quantum Cryptography Coalition

Nice heatmap over PQC adoption in major protocols, security solutions. Not stated, but probably all use NIST ML-KEM and ML-DSA, not other PQC algorithms. Also there seems to be preference for hybrid solutions.

Gick upp 20 kilo för att slippa lumpen – döms En man i Sydkorea har dömts till villkorligt fängelse för att ha undvikit sin militärtjänstgöring – genom att medvetet ha gått upp i vikt.

Detta är olagligt även i Sverige. Brottet heter "svikande av försvarsplikt".

Happy AES cipher day!

On this day, 23 years ago NIST published FIPS 197.

I keep coming back to that performance. The difference in artistry, the way he looked compared to the others. And the way he played. He is sorely missed.

The Ruble continues its negative advance and downward growth.

I don’t think the US government appreciates the degree to which Signal and end-to-end encryption has become a national security requirement — following the deep penetration of US telecoms by China.

The Russian ruble in freefall — having breached the 100 barrier despite a 20% interest rate — is a beautiful sight to see.

Not sure how I missed this: NIST is deprecating and then outright disallowing elliptic curve cryptography for key establishment as well as for digital signatures by 2035: nvlpubs.nist.gov/nistpubs/ir/...

Israel’s a nuclear power. Hamas should negotiate and cede territory.

Apparently that’s how this works.
