“Are they a single point of failure in that regard?” It depends. If the ACME client is configured to only use Let’s Encrypt, then the answer is yes. But the client could fall-back to Google’s CA, ZeroSSL, etc. And then there is no single point of failure.

Makes sense. I assume each of them is in control and at the whims of US president?

It seems that currently most free CAs have a big presence in the US, and employ quite a few US employees.

ZeroSSL/HID Global seems to be quite multi-national though, and it’s owned by a Swedish company (Assa Abloy).

I don’t know what what kind of mitigations these orgs have in place if the shit really hits the fan in the US. It’s an interesting question for sure.

They are not in control of the US president.

I'm pretty sure that the .org TLD can be shut off by the US at any point in time.

That’s not relevant though. These CAs will gladly give you a .se/.dk/.in/whatever cert as long as validation passes.

Next, I hope they focus on issuing certificates for .onion addresses. On the modern web many features and protocols are locked behind HTTPS. The owner of a .onion has a key pair for it, so proving ownership is more trustworthy than even DNS.

It's a huge ask, but i'm hoping they'll implement code-signing certs some day, even if they charge for it. It would be nice if appstores then accepted those certs instead of directly requiring developer verification.

1) For better or worse, code signing certificates are expected to come with some degree of organizational verification. No one would trust a domain-validated code signing cert, especially not one which was issued with no human involvement.

2) App stores review apps because they want to verify functionality and compliance with rules, not just as a box-checking exercise. A code signing cert provides no assurances in that regard.

Also I don't see the point of what TLS is supposed to solve here? If you and I (and everyone else) can legitimately get a certificate for 10.0.0.1, then what are you proving exactly over using a self-signed cert? There would be no way of determining that I can connecting to my-organisation 's 10.0.0.1 and not bad-org 's 10.0.0.1.

A public CA won’t give you a cert for 10.0.0.1

Exactly - no one can prove they own it (on purpose because it's reserved for private network use, so no one can own it)

If I can use my DHCP assigned IP, will this allow me to drop having to use self-signed certificates for localhost development?

No, they will only give out certificates if you can prove ownership of the IP, which means it being publicly routable.

It's just control isn't it, not ownership? I can't prove ownership of the IPs assigned to me, but I can prove control.

How are IP address certificates useful?

* DoT/DoH * An outer SNI name when doing ECH perhaps * Being able to host secure http/mail/etc without being beholden to a domain registrar

IP addresses arent valid for the SNI used with ECH, even with TLS. On paper I do agree though it would be a decent option should things one day change there.

I mean if it's not routable how do you want to prove ownership in a way nobody else can? Just make a domain name.

This is assuming NAT, with IPv6 you should be able to have globally unique IPs. (Not unique to IPv6 in theory, of course, but in practice almost no one these days is giving LAN devices public IPv4s).

But isn't it unnecessary to use https, since tor itself encrypts and verifies the identity of the endpoint?

It would give you a certificate chain which may authenticate the onion service as being operated as who it purports to. Of course, depending on context, a certificate that is useful for that purpose might itself be too much if an information leak
