support boringssl support

[GlenDC]

especially for the client side this is needed to emulate TLS using boringssl directly (for chromium profiles)

Hey Glen, I want to take a stab at this one, but I'm not really sure where to begin. I noticed we do have rustls client so I figured it may be similar to that but other than that, I'm not sure how to proceed.

Hi @AlvinKuruvilla if it's all the same with you I would prefer it if you can pick up an unassigned issue. When I assign them to me already it means that I either want to do it myself, or that I am not yet 100% certain what I exactly want from the ticket. In this case it's about the 2nd. Let me elaborate, if you will.

• This issue can be split into several parts, some parts are to do with the client side, others are to do with the server side;
• The server side is for now the most pressing as I want to also use this in rama-fp to get the exact and complete client hello, because for now I use rustls here and that gives an incomplete picture. E.g. I miss a lot of extensions and other data;
• The client side is also needed for the v0.2 release, but that can wait until later in the milestone as anyway first the entire UA part still needs to happen. Unrelated, but also something I wanted to do first is embedding the hyper fork in the codebase, and so forward
• For the client side we'll also need to provide a wrapper that can handle multiple TLS backends, e.g. such that based on some way to configure it it will use either rustls or boring
• Both server and client sides are to be implemented as middleware (layer services)
• It is unclear to me though what exact implementation details are needed (E.g. what to expose, what to allow to configure, etc etc...)

So TLDR: I honestly do believe you are more then capable enough to do this ticket. I would however regret it if I "burn" you out just because of me not knowing exactly what and how I want the code regarding this ticket and as a consequence it might result in very long winded Pull Requests will a big ping-pong review cycle. That said, perhaps you have a better vision of it all, based on me putting this message out, and feel more then ever motivated to still do it. If so, I suggest you hop on discord and we try to have an interactive chat about it all.

But of course, as I hinted earlier, maybe for now, you can pick up an unassigned issue, and preferably one with the "good first issue" label.

Do let me know what you think. And we can take it from there.

I agree with you and I appreciate the details you provided.
