people are always talking about a hypothetical technologically advanced alien race ... but I always wonder, if they exist, do they also have to deal with PKI?

The disagreement is just whether “memory safety” is a programming language theory definition or a security one. I think you are wrong to say it’s “embarrassing” for people to choose the other definition, and reasonable people can be on both sides of this fence.
Earlier this year, LWN.net featured an excellent article named "Linux's missing CRL infrastructure", and today
Canonical announced it will be working with me and @jbp.io over the coming weeks to start bridging the PKI infrastructure gap.

anyone need their horse rotated?
I spent a bit of time poking around the Firefox codebase and filed a bug with the findings: bugzilla.mozilla.org/show_bug.cgi...
Those entries are a combination of both Kamu SM as well as roots which have been locally added to Firefox's trust store
I think it’s a data error, possibly on Mozilla’s part - I found a comment suggesting bins 0 and 1 are reserved, but recently they put Kamu SM into bin 1. Maybe I’ll just exclude those suspicious bins.
Bar chart showing the largest CAs in Firefox's telemetry are Google, Digicert, ISRG, AWS, Entrust, Sectigo, Globalsign, and Godaddy. Other entries are all much smaller.
Firefox's telemetry has data on how many times a CA is used to successfully validate certificates. This is a pretty good measure for how "big" a CA is. The data is hard to view in Mozilla's site, so I've made a script to combine a few data sources and graph it! github.com/mcpherrinm/c...
Customers: We want a faster horse
Henry Ford: Ah. In fact—
Kubernetes: Let me stop you right there. What you really need is 1000 horses that die randomly
Inspired by the classic xeyes program, I made a thing:
ssh teyes.fly.dev
Or go install github.com/mcpherrinm/teyes@latest && teyes

I'll be speaking at the Ontario #Cryptography Day!
ontario-crypto-day.github.io
Where: University of Waterloo Davis Centre (DC) 1301 and 1302
When: Friday, June 6, 2025, from 10am to approx. 4:30pm
I hope anyone in the area interested in cryptography is able to attend!

OK, this is wild.
In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them.
It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*.
What the HELL?

A lot of Americans don't know this, but the winner of the Canadian election will be required live in a small cottage located in the backyard of the palace where the viceroy to the King of England lives.
The cottage just recently got a new wifi router, which was very exciting for all Canadians.

We've issued our first short-lived (6 day) certificate! letsencrypt.org/2025/02/20/f...
The key line here is:
> ... certificates issued on or after June 15, 2026 MUST include the extendedKeyUsage extension and only assert an extendedKeyUsage purpose of id-kp-serverAuth.
Chrome has published version 1.6 of their root store policy.
Notably, this includes a deadline of June 15, 2026 to get TLS Client Auth out from any intermediates under roots in Chrome's program.
TLS client cert users from public CAs may need to make changes.

Canadian MP Charlie Angus: Our beloved Canada is under threat.
The threat comes from the president of the US—a convicted felon and known predator. But the threat is also being driven by the hate algorithms of oligarchs like Elon Musk….
