It looks like on the stats page, the "Let's Encrypt Growth" and "Let's Encrypt Certificates Issued Per Day" graphs only have data through Feb. 2, though I vaguely remember in the past them having data up to almost the current day. The "Percentage of Web Pages Loaded by Firefox Using HTTPS" graph still has data up through yesterday, for instance.
The Issuance stats are out of date and we are working on updating them.
Thanks. I was wondering if I was just imagining things and they'd usually been a couple months behind. I'm sure it's not the most pressing issue for you to all be working on, but I'm just amazed at how issuance is regularly over 2 million certs per day nowadays and occasionally like looking at the stats.
They occasionally fall behind and various things affect the priority of getting them totally caught up. I'll bump it a little since It's much further behind than usual. Thanks for the reminder!
Part of why I was looking was that I was also wondering if there were other stats, like how adoption of ECDSA certificates is going. But then it occurred to me that a lot of those kind of statistics ought to be able to get derived through certificate transparency records, though I don't know as anybody's put anything together to aggregate that kind of stuff. Most of the CT aggregation sites I've seen (and I don't think there are that many) are focused on getting info about specific domains rather than info on the WebPKI as a whole.
I'm not sure how long crt.sh can keep up with 'counting' big numbers but this is a quick way to see the E1 ECDSA cert counts. crt.sh has pages for all the PKI intermediates it knows about, we offer links for each of the Let's Encrypt: intermediates Chain of Trust - Let's Encrypt - Free SSL/TLS Certificates
Ah, once all the ECDSA certificates get signed by a different intermediate (E1) then yes that would give the data. I was wondering what percent of certificates would that be, that is what percent of certs signed by R3 today are ECDSA vs. RSA. (And that'd be just for Let's Encrypt, though now that I'm talking about it I wonder how it compares to other CAs as well.)
No big deal, I'm just being overly curious. Thanks again!
One example for this is Cloudflare's "Merkle Town": https://ct.cloudflare.com/
Awesome! That's just what I was looking for. Thanks!
Ahhh, I see. crt.sh might have ways to reduce the information down to key-type.
The stats page is updated!
Thank you. Continuing the pace of 2 million cert issuances a day and rising! Just absolutely incredible.
