Was the socket.IPPROTO_SEC variable removed from Micropython 1.8, since most examples online have it. If not, is there any way I could get the variable, without having to rebuild the whole firmware?

>>> sock=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> import ussl as ssl
>>> s=ssl.wrap_socket(sock)
ssl_handshake_status: -256
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [Errno 5] EIO

Running this on the Esp8266 NodeMCU and Micropython Version 1.8.6

I might be wrong, but IPPROTO_SEC is available for WiPy. Which "most" examples are you referring to and what board are you using?
http://docs.micropython.org/en/latest/w ... pproto_sec

You're right, I'm using the esp8266 Node MCU and used examples for the Wipy. I was trying to use ssl to wrap a socket and kept getting an "ssl_handshake_error:-256" I thought this was the error.

I'm currently unable to post data to secure "company" sites for a project I'm doing and this is because the ssl handshake fails.
I believe the reason to be because the current ussl module doesn't Validate server certificates.

Is there any ssl.wrap.socket () out there that does this?

">>ssl_handshake_status:-256"
Thank you in advance.

Can you also include the version of MicroPython that you are using and the board on which you are running it?

Done

This is, indeed, an error, I am going to merge your two topics together and move it to the esp8266 category.
Please don't cross-post and don't create multiple topics for the same issue.
