pycurl and SSL cert


You are right, the way you are doing it subjects you to a man-in-the-middle attack, especially in light of the most recent SSL vulnerabilities. You can resolve it as follows:

import pycurlcurl = pycurl.Curl()curl.setopt(pycurl.URL, "https://your-secure-website.com/")curl.setopt(pycurl.SSL_VERIFYPEER, 1)curl.setopt(pycurl.SSL_VERIFYHOST, 2)curl.setopt(pycurl.CAINFO, "/path/to/updated-certificate-chain.crt")curl.perform()

curl by default comes with an outdated certificate list. Whether you want to update it or just use your own certs for testing, make sure to place the updated-certificate-chain.crt file in an accessible location and use the pycurl.CAINFO option to point to it.

Also make sure pycurl.SSL_VERIFYHOST is set to 2, the highest security check setting.


Have you read the cURL documentation about SSL certificates? This seems to directly address your question...in particular, item 2:

 2. Get a CA certificate that can verify the remote server and use the proper    option to point out this CA cert for verification when connecting. For    libcurl hackers: curl_easy_setopt(curl, CURLOPT_CAPATH, capath);

It looks like the pycurl module contains the CAPATH option, so this should be simple to implement in your code.


The Solution to this problem lies in providing the curl object access to the 'https' based protocol url's via insecure argument In a cmd terminal we exclusively input the arg '-k'

In Pycurl we have to set the same option to the curl object by the methods as below, with minimal level of security i.e '0'.

c.setopt(pycurl.SSL_VERIFYPEER, 0)   c.setopt(pycurl.SSL_VERIFYHOST, 0)

allow the insecure connectionAfter which, access to the SSL is made without any obstruction
