Python Requests getting SSLerror
python, python-requests, ssl, ssl-certificate
Solution
The certificate itself for www.reporo.com (not reporo.com) is valid, but it is missing a chain certificate as shown in the report by ssllabs:
Chain issues Incomplete
....
2 Extra download Thawte DV SSL CA
Fingerprint: 3ca958f3e7d6837e1c1acf8b0f6a2e6d487d6762
The "Incomplete" and "Extra download" are the major points. Some browsers will have the missing chain certificate cached, others will do the download and other will fail. If you try the site with a fresh Firefox profile (which does not have any certificates cached) it will fail too.
You could download the missing chain certificates and use it as trusted CA certificate with the `verify` parameter for requests. Don't just disable validation because then you are open to man-in-the-middle attacks.
Step by step instruction:
- Download the missing certificate at https://ssl-tools.net/certificates/vqgvhb-thawte-dv-ssl-ca (found by searching for the fingerprint given in the report from SSLLabs). Download the file in PEM format, i.e. https://ssl-tools.net/certificates/3ca958f3e7d6837e1c1acf8b0f6a2e6d487d6762.pem.
- Download the root certificate at https://ssl-tools.net/certificates/91c6d6ee3e8ac86384e548c299295c756c817b81.pem (also found by searching for fingerprint).
- Cat both files together into a new file `chain.pem`. Make sure that each of the files did end with a valid end of line character (which they do not as downloaded). The resulting file should look like this.
Modify your call to
requests.get('https://www.reporo.com/', verify = 'chain.pem')
Problem
Trying to make a simple get request using Requests session but I keep getting SSLerror for a specific site. I think maybe the problem is with the site (I did a scan using https://www.ssllabs.com, results are down bellow), but I cant be sure because I have no knowledge in this area :) I would sure like to understand what is going on. A solution/explanation would be great, thanks! The code: ``` import requests requests.get('https://www.reporo.com/') ``` I'm getting the next error: ``` SSLError: [Errno bad handshake] [('SSL routines', 'SSL3_GET_SERVER_CERTIFICATE', 'certificate verify failed')] --------------------------------------------------------------------------- SSLError Traceback (most recent call last) <ipython-input-7-cfc21b287fee> in <module>() ----> 1 requests.get('https://www.reporo.com/') /usr/local/lib/python2.7/dist-packages/requests/api.pyc in get(url, **kwargs) 63 64 kwargs.setdefault('allow_redirects', True) ---> 65 return request('get', url, **kwargs) 66 67 /usr/local/lib/python2.7/dist-packages/requests/api.pyc in request(method, url, **kwargs) 47 48 session = sessions.Session() ---> 49 response = session.request(method=method, url=url, **kwargs) 50 # By explicitly closing the session, we avoid leaving sockets open which 51 # can trigger a ResourceWarning in some cases, and look like a memory leak /usr/local/lib/python2.7/dist-packages/requests/sessions.pyc in request(self, method, url, params, data, headers, cookies, files, auth, timeout, allow_redirects, proxies, hooks, stream, verify, cert, json) 459 } 460 send_kwargs.update(settings) --> 461 resp = self.send(prep, **send_kwargs) 462 463 return resp /usr/local/lib/python2.7/dist-packages/requests/sessions.pyc in send(self, request, **kwargs) 571 572 # Send the request --> 573 r = adapter.send(request, **kwargs) 574 575 # Total elapsed time of the request (approximately) /usr/local/lib/python2.7/dist-packages/requests/adapters.pyc in send(self, request, stream, timeout, verify, cert, proxies) 429 except (_SSLError, _HTTPError) as e: 430 if isinstance(e, _SSLError): --> 431 raise SSLError(e, request=request) 432 elif isinstance(e, ReadTimeoutError): 433 raise ReadTimeout(e, request=request) SSLError: [Errno bad handshake] [('SSL routines', 'SSL3_GET_SERVER_CERTIFICATE', 'certificate verify failed')] ``` I ran a scan at https://www.ssllabs.com and got the following: ``` SSL Report: reporo.com Assessed on: Sun Feb 22 21:42:57 PST 2015 | Clear cache Scan Another >> Server Domain(s) Test time Grade 1 154.51.128.13 Certificate not valid for domain name reporo.com Sun Feb 22 21:40:53 PST 2015 Duration: 9.167 sec - 2 198.12.15.168 protected.ddosdefend.com Ready www.reporo.com Sun Feb 22 21:41:02 PST 2015 Duration: 115.189 sec F ```
