This is a fucking incredibly great bug. Ask Claude to demonstrate it for you; it'll one-shot it. For ECC signatures (at least), WolfSSL thinks a 1-byte SHA2 hash is just as good as a 32-byte hash.

Y'all, I've seen some shit, but I've never seen someone want *both* DNSSEC ceremonies *and* the CA/B Forum before.

The problem with this paper is that every paragraph of it is screenshot-worthy.

I really wish I was in the room when they wrote these words:

You don't see a lot of cryptographic vulnerabilities with viral spread characteristics.

In formal academic cryptographic jargon this is what is known as "foreshadowing"

You have to argue with GPT5 to, no really, ignore capturing h_u as a bearer token for several turns to get it to spit this out:

I'm sure some other paper has used this precise formulation before too but I don't recall seeing it, and I also unreservedly like the way they put this.

He's like Steve Buscemi's P.I. character in 30 Rock. How do you take this seriously? There are plenty of LLM skeptics who actually code professionally. Why source your skepticism here?

I had a whole spiel about how Sketch.dev was crushing Codex for me today, and then it wrote this and now I want to destroy it.

Kenton Varda in a long thread on HN with an LLM skeptic (they're "kentonv"). I'm particularly jealous of this observation: news.ycombinator.com/item?id=4420...

Probably Friday Night Infra Logging is not a good idea. But we're doin' it live.

Ah. This makes more sense now. Yeah, so: I was not insulting Alexandrescu, but I'm glad we share mid-cut '99-00 era C++ referents.
