Are you interested in particular types of scientist? I.e., physicists, chemists, biologists? Computer scientists? :)

> I don't know of any issuer key compromises detected with CT. Such compromises are rare. DigiNotar is an obvious example, but can you think of any recent ones? Not key compromise,…

Is Cirrus mentioned in the blog post? I can't find it. Right now, the way key compromise might be detected in RPKI is that a human network operator notices a signed object which is…

IPFS offers content integrity, which you can use to bootstrap confidentiality.

Not sure if this fully addresses your use-case, but I like the idea of serving a static bootloader from IPFS. The bootloader would contain all of a website's assets, and code for g…

I believe the IPFS team has already built a browser extension that runs a js-ipfs node. Running an IPFS node is not ideal for power and bandwidth constrained devices like a mobile …

No plans currently. I'm not really familiar with Dat. Can it do something that IPFS can't?

Kiwix has an archive of StackOverflow but its gigantic. :( We barely got the Math StackExchange uploaded in time.

> And ultimately, how can I know for sure that CloudFlare won't play the game where as acting as a proxy they will modify some of the files served? https://blog.cloudflare.com/e2e-…

There are lots of scenarios where you would want to let an untrusted intermediary handle critical operations for you without actually having to build trust with them. Typical examp…

Not for a while. DJB's curves have entirely too much structure and I'd prefer to get something general purpose working first. I don't even like having to implement NIST's speedup f…

I've tested a scalar of about 50% 1s against a scalar with almost no 1s, measuring at the nanosecond resolution, with 100 samples each. The p-value of the 2-sample T-test was great…

Issue #1: Yes, it's supposed to be like that. The point is that any n-bit scalar takes the same amount of time as any other n-bit scalar. Issue #2: Rust has explicitly taken all me…

I missed my edit window... I actually take the above back. Scalar multiplication on a point IS constant-time (the two distributions are indistinguishable). Field exponentiation isn…

About ElGamal: Agreed. I only planned to implement it for my own satisfaction, more than for anything else. The addition law only leaks general cases--doubling, negatives, one argu…
