ACME v2 and Wildcard Certificate Support is Live

Call me an idiot but I couldn't figure it out at first.

Apparently you need add "--server https://acme-v02.api.letsencrypt.org/directory" to your Certbot command to tell it to use the API that supports wildcard certificates.

I use this one:

https://github.com/lukas2511/dehydrated

and

https://github.com/kappataumu/letsencrypt-cloudflare-hook as the hook provider to update Cloudflare DNS.

I was able to create a wildcard certificate last night using them together :)

Great! Now I just need to upgrade to a client that supports those, pretty sure le.pl isn't being actively developed any more…

Useful for dynamically created subdomains

This should enable such things as self-hosting Sandstorm on your own domain, which is great. Sandstorm relies on using dynamically created subdomains to give each application instance it hosts a separate cookie domain.
