Need solution for asyncio SSL/TLS connections #8647
Description
I am running esp32c3-usb-20220117-v1.18.bin
TL;DR
How to open a SSL or TLS connection using uasyncio?
I am tryign to port a CPython project onto Micropython.
In CPython asyncio, we could open a SSL connection easily by using ssl argument in asyncio.open_connection() method.
When I am trying to use uasyncio.open_connection(..., ssl=True), it raises an exception saying that there's no ssl argument. We can confirm it on the doc page here.
Then I try to use ssl module to warp the socket in StreamWriter.get_extra_info("socket")(I never test this, I don't know whether this would work, just have a try), but I cannot get the "raw" socket of this connection, because function uasyncio.Stream.get_extra_info only accept "peername" as a param, no support for "socket". We can check it here.
If there's a method to open an SSL/TLS connection by using uasyncio? I really want to use asyncio because I think that is the best part of python language.

Here is the code https://github.com/RuofengX/uPyxy/blob/c3772838be208056282e01ed0d3f8da0c8fa4de8/main/lib/client.py#L103

You might like to look at mqtt_as which uses nonblocking sockets and works over TLS.

I implemented a workaround for my project here. It's basically a custom connection maker based on the original one.

I ran into this last week and also implemented my own asyncio friendly implementation. My version is optimized for my application, but asyncio ssl open_connection is surely something that would be apprecaited by future travelers.
I will also agree asyncio is my favorite part of python language! Game changer for microcontroller dev.

Asyncio SSL server and client are now supported.
