SSL library

[sniperini]

Hello,

I am trying to enable SSL on my ESP32 Micropython latest compiled FW, but unfortunately your following requirements for SSL python library are hard to comply:

The ssl library must be implements SSLContext on Python 
version to support secured web server

The ussl (https://github.com/micropython/micropython-lib/blob/master/ssl/ssl.py) library that Micropython uses doesn't have create_default_context method and SSLContext class and , only wrap_socket method from it.

Same goes for Pycom: https://docs.pycom.io/firmwareapi/micropython/ussl/

The only one I found that has everything, is CPython full implementation of SSL.
https://github.com/python/cpython/blob/master/Lib/ssl.py

But then again, micropython doesn't have all those dependencies to even load it, starting from importing Enum module... Basically it needs to be rewritten how it was done with USSL.

Could you please clarify which library are you using that has that SSLContext class and create_default_context method?

Is it possible to adopt MicroWebSrv2 to comply with Micropython implementation of SSL somehow?

Thanks!

Hello @sniperini, and thank you for your interest 👍

About SSL, I know very well that SSLContext doesn't exists on MicroPython but the standard wrap_socket method and other implementations with a differed handshake do not works correctly in asynchronous mode and moreover, supported SSL versions are old.
For the moment, it is therefore intentionally that there is no support.

I was reading into this, still learning, and it throws a wrench in the plan I had. I want to run a little server on a Pycom Wipy 3.0, with secure log in.

Is there a way this could still be realized?

Hi,
I'm sorry but on MicroPython for Pycom, SSL client support is ok but the server mode is restricted and causes problems with web browsers to properly negotiate the TLS layer...
I was also disappointed. :(
