usocket and ussl https server

[gringtc]

I'm trying to setup an https server with sockets and ssl in micropython as shown here http_server_ssl.py.

When using exactly the example with the given key and cert, I get this error when connecting to the server via chrome on my laptop:

Logs:

Bind address info: [(2, 1, 0, '', ('0.0.0.0', 8443))]
Listening, connect your browser to https://<this_host>:8443/
Client address: ('192.168.0.104', 64191)
Client socket: <socket state=3 timeout=-1 incoming=0 off=0>

Error:

Traceback (most recent call last):
  File "<stdin>", line 95, in <module>
  File "<stdin>", line 65, in main
OSError: (-30592, 'MBEDTLS_ERR_SSL_FATAL_ALERT_MESSAGE')

line 65: client_s = ssl.wrap_socket(client_s, server_side=True, key=key, cert=cert)

When using my own signed key and cert like this:

with open('certs/privkey.pem', 'rb') as f:
    key = f.read()
with open('certs/cert.pem', 'rb') as f:
    cert = f.read()

I get an invalid key error:

Traceback (most recent call last):
  File "<stdin>", line 69, in <module>
  File "<stdin>", line 39, in main
ValueError: invalid key

Any help with setting up the https server would be appreciated. Thanks!

@gringtc
OSError: (-30592, 'MBEDTLS_ERR_SSL_FATAL_ALERT_MESSAGE')
This is the browser response to a self-signed certificate, to avoid this you need to add the self-signed certificate to the trusted sources in chrome, see https://stackoverflow.com/questions/7580508/getting-chrome-to-accept-self-signed-localhost-certificate

For ValueError: invalid key see https://github.com/micropython/micropython/tree/master/tests#test-keycertificates instructions to generate a key/cert pair (MicroPython only supports DER format by default, unless using esp32 port)
