Great work! Possible to show auto letsencrypt cert renewal with reverse proxy example?

1. Possible to show auto letsencrypt cert renewal with reverse proxy example?

Looking to use as replacement to current implementation.

2. Also, possible to integrate with monoio's hyper?

Possible to show auto letsencrypt cert renewal

It's definitely possible. But the example would be quite large since it needs to also include a HTTP/1 server to respond to the ACME challenges.

with reverse proxy example?

A reverse proxy example should be pretty straightforward. But note that s2n-quic doesn't ship with a HTTP/3 implementation so that would need to come from h3, for example. You can see an example of how to integrate with it in the s2n-quic-h3 crate. Keep in mind that the h3 crate does not have a release on crates.io so the API might change/break at any time.

Also, possible to integrate with monoio's hyper?

Hyper currently does not have HTTP/3 support (see hyperium/hyper#1818 (comment)). You'd have to use the h3 crate directly. But it should be possible to use that with tower.

Regarding monoio: it doesn't appear to have any UDP support so that wouldn't be possible: https://github.com/bytedance/monoio/tree/master/monoio/src/net.

@hiqsociety I've been working on a similar project.
You can find an example of getting a Letsencrypt cert here using DNS, not HTTP/S challenges:
