Python - requests.exceptions.SSLError - dh key too small

Question

I\'m scraping some internal pages using Python and requests. I\'ve turned off SSL verifications and warnings.

requests.packages.urllib3.disable_warnings()
p         


        

Answer 1

this is not an extra answer just try to combine the solution code from question with extra information So others can copy it directly without extra try

It is not only a DH Key issues in server side, but also lots of different libraries are mismatched in python modules.

Code segment below is used to ignore those securitry issues because it may be not able be solved in server side. For example if it is internal legacy server, no one wants to update it.

Besides the hacked string for 'HIGH:!DH:!aNULL', urllib3 module can be imported to disable the warning if it has

import requests
import urllib3

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

page = requests.get(url, verify=False)
