It's difficult to determine whether you follow an argument when you summarize it in a way that sounds incorrect.
If that's an attempt at highlighting that what you summarized is not persuasive, your tactic also isn't very persuasive. Instead it comes across as snarky, dismissive, or that you misunderstood. It might be worth reconsidering this tactic.
The main reason I wouldn't pick Ed448 is simpler: Nothing else really uses it.
- tptacek 4y agoFor what it's worth, I'm responding to this: There was a recent flurry of buffer overflows in SHA3 implementations. I'm aware of at least PHP being affected. Wanting Ed448 for political reasons, or purely for psychological comfort reasons, is a perfectly understandable stance to take as a non-expert. Unfortunately, the details that experts are privy to matter a ton, and severely outweigh any notions of having eggs in multiple baskets. We're open to having our risk calculus checked, but we're nearly unanimous on this one. Who's "we" here? I think Filippo has a mainstream take on the 448 curves, but I don't know that your take on SHA3 is widely shared.
- some_furry 4y agoWe here is people who don't advise using Ed448. It's tautology. You don't have to agree with the specific reason I cited. That isn't encapsulated by "we". I was providing an additional argument in case the mainstream take isn't sufficient. You cut the "To add to what Filippo said" part out of the excerpt you quoted, which was the necessary context to understand I was making an additional, supplementary argument.
- tptacek 4y agoI don't agree with the specific reason you cited, which is what I wrote about.
