@jonfoster you may be interested in #633, see the [README](https://github.com/Carglglz/micropython-lib/tree/certifi/micropython/certificates)

@wohltat yes this is known see #846

@wohltat your test does not do what you think is doing e.g. ```py # allocate and prepare fixed block of data to be sent b = bytearray(10_000) for k in...

I think this is the same as #846

@felixdoerre this could be a good opportunity to add SSL support to WebREPL using `SSLContext` see https://github.com/micropython/micropython/pull/5611#issuecomment-1314686679 👍🏼
