Async SSL/TLS server

[clue]

Migrated from reactphp/reactphp#2, originally reported 2012-05-11

This ticket aims to serve as a basis for discussion whether (and how) we should provide an async SSL/TLS server.

A possible alternative is to launch a SSL/TLS proxy server (such as stunnel, haproxy or nginx) in front of your unencrypted socket server.

I'm curious why there is no 1st party support for this yet? That old pull request basically had the gist of it all right. As for the alternative, once #25 is resolved, this issue will be a little more than a matter of parity between the server and client side capabilities of react and their completeness since we can actually set up a proper IPC socket between the two at that point, rather than using the loop back interface.

Ironically, php's openssl extension, and subsequently anything TLS related, seems to suffer a bit from the same problem as openssl itself when it comes to how they are documented (or lack thereof in some cases). The PHP 5.6 migration guide is the only official documentation that mentions most of the "recent" and relevant changes to PHP as far as I know.

Personally, I prefer this https://wiki.php.net/rfc/improved-tls-defaults to the migration guide, at the time of writing this though, because it seems to still be at least as accurate and more verbose than the former.

Just a heads up: I've started looking into this while trying to add test cases for our socket-client component: reactphp-legacy/socket-client#62

The resulting SSL/TLS socket server works reasonably well and I'll look into filing a PR for this in the upcoming weeks

However, we currently have to share some classes with the socket-client component, so I'll look into moving these elsewhere first. I'll keep this ticket updated.

Any E.T.A. on this? Need to know if I should continue using my own hack for now or wait for this in order to meet my own deadlines.

Any E.T.A. on this?

Unfortunately not. If your "own hack" works fine, I recommend you stick with it for the time being 👍

That being said, this task is high on my todo list and I plan on picking this up in the next week. However, this currently depends on reactphp/stream#42 first if we want to avoid some rather nasty hacks here.

Progress update: All referenced issues have been resolved in the meantime. The next (last!) batch of dependencies is #49, #50 and #51.

I'm ready to file a PR for my SSL/TLS server implementation once these are finally in
