Error when running example.py (SSL key to small) with SSL version 1.1.1d

[Rubske70]

Hi,

I'm getting the following error when running example.py on my Pi4 with latest raspbian

OpenSSL.SSL.Error: [('SSL routines', 'tls_process_ske_dhe', 'dh key too small')]

Any ideas?

Thanks for your help!

Hi! SSL errors usually indicate problems with your Python installation. Sorry I can't help more than that!

Thanks for the quick reply, i will search in that direction!

I did some investigating and think it's related to the latest python version including openssl 1.1.1d on my Windows 10 it's working with 1.1.1c

Do you think this could be true?

Seems to happen with anybody on Python 3.7.3 and openssl 1.1.1d

Hopefully anybody knows a solution..

Thx

A quick workaround is by adding this at the bottom of init.py

requests.packages.urllib3.disable_warnings()
requests.packages.urllib3.util.ssl_.DEFAULT_CIPHERS += 'HIGH:!DH:!aNULL'
try:
    requests.packages.urllib3.contrib.pyopenssl.DEFAULT_SSL_CIPHER_LIST += 'HIGH:!DH:!aNULL'
except AttributeError:
    # no pyopenssl support used / needed / available
    pass
