[-]Module uasyncio is lack of support for SSL/TLS support.[/-][+]Need solution for asyncio SSL/TLS connections[/+]on May 10, 2022 You might like to look at mqtt_as which uses nonblocking sockets and works over TLS.
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.
Reacted by Peter HinchAsyncio SSL server and client are now supported.

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
sslargument inasyncio.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 functionuasyncio.Stream.get_extra_infoonly 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.
