letsencrypt VS libsignal

This seems to be not implemented in certbot, yet: https://github.com/certbot/certbot/issues/6566

If you do go with NPM or Traefik, under the covers it's using certbot to request/renew your certificates through Let's Encrypt using the DNS-01 challenge, meaning you can get wildcard certs and don't have to futz around with port forwards. Again I'd think Caddy has similar functionality, I just have not used it personally. Raw NGINX you probably don't want to try out yet considering it requires manually doing the configs

certbot won't be missed. The code quality is pretty poor.

https://github.com/certbot/certbot/issues 5000 bugs and it most of it can be replaced by much smaller tools

Here’s a good code reference (Python and rust): https://github.com/certbot/certbot

I am trying to migrate off of Linux and back to FreeBSD, but I hit a problem today. The Let's Encrypt Certbot is not installing. A bit surprising, given how important it is. So I thought I would notify the community Here is my bug report. https://github.com/certbot/certbot/issues/9394

Last release: https://github.com/certbot/certbot/releases (on 28th August 2022 = 1.29.0)

Right? It’s so ridiculous how you’re supposed to use Snap to install certbot. The (well, one of..) GitHub discussion is just beyond the pale:

https://github.com/certbot/certbot/issues/8345#issuecomment-...

It goes way beyond, since Let's Encrypt influence the ecosystem a lot and the standards that are used.

If you use Let's Encrypt, you are likely using Certbot, which means that everybody uses a tool that a central authority strongly recommends to you.

I wonder how they generate the key, for example, it may be using secp256r1: https://github.com/certbot/certbot/blob/5c111d0bd1206d864d7c...

I am in the process of building a Go implementation of the libsignal-protocol, which powers the Signal app.

How is twitter intending to use libsignal? I doubt it would be via the primary AGPL license[1], forcing them to publish the source code of their server source code. Does signal sell private licenses?
