Fair point! I think that quote should read "a random coprime to [...] to ϕ(n)". Then it makes sense. There's a lot of math behind RSA computation and we were trying to distill as much as we could, but it's not perfect. W

It's most likely to be Fly-specific, but you could replicate this behavior with passing appropriate to tls.Config#GetCertificate ( https://golang.org/pkg/crypto/tls/#Config ). You could then have something

tptacek: I think this sub-thread has been mainly to explain what RSA could be used for, not that it would be a good idea. On the side note, I have been positively surprised to see how many devices support ECDHE key exchange. Also, do you ha

what encryption are you talking about? IIRC, RSA has only been used for key exchange or authentication (sign/verify) in SSL/TLS. Even in the old days up to SSL 3.0, RC4 or (3)DES was used for actual (symmetrical) encryption.

you can also use RSA for actual encryption (like PGP) or for signing/verifying. ECDHE is better for key exchange, and ECDSA is better for signing/verifying. Check out goodroot's link!

Oh, and we use the basic Ghost theme, Casper, with some design tweaks.

Thanks! We're using ghost.org and of course all our illustrations are done by Annie ( https://twitter.com/annieruygt ) :)

Yeah A/CNAME to us and then you can use our API to issue certs of all subdomains or if you have a wildcard cert already you can upload that with us. Either way works :)

by matahwoosh 9y ago
for the time being, you could try to issue SAN certs with LE (from their website): "If you have a lot of subdomains, you may want to combine them into a single certificate, up to a limit of 100 Names per Certificate. Combined with the

Ohai! Yeah, you can do the same thing with Fly (which is what most of our customers do - just point DNS at Fly). I cannot stress enough how nice it is being able to build on top of Let's Encrypt! bows The API is mainly for people who

I'm assuming mrkurt meant that you send your users once to create a dns record (in case you haven't already) - you can add any hostname you want on Fly, it doesn't have to exist, yet. Then you go and create a DNS challenge fo

I think there's no straightforward answer to this. E.g. why would you have 2 DNS look-ups with cookieless domain? I imagine that means cdn.mydomain.com and mydomain.com? If you're using HTTP/2, then one domain is better, beca

I agree with you that the earlier you can catch those performance issues, the better. It's just like with catching bugs early in your development cycle. You could even argue that poor perf is a bug! The more you know about the performa

Also, a note on QUIC. Seems like the spec is a draft and is not going anywhere right now, but Google has made big progress with TCP BBR control-flow algo, and there's also TCP Fast Open and TLS 1.3 0-RTT to look forward to. Moving more

There's definitely some truth to how (at least some of) e-commerce sites could be easily sped up. Part of the problem is that you have a combination of legacy stack, organizational inertia, lack of know-how and resource outsourcing (so

Generally, yes, but I think `O(log n / log log n) == O(log n)` is wrong. log(n) / log(log(n)) = logx(n) (where x = log(n), wasn't sure how to describe logarithm base in a better way). So you get O(logx(n)). In general the log

small correction, it's Θ( log n / log log n ). I noticed though, when I copied the formula from the original paper, this what I got, too ;)
