title: Verify SSL certificate with Requests
body: <p>I'm trying to verify SSL but it doesn't work.</p>
  <ol>
  <li>I went on the confidential website I wanna get, on my browser.</li>
  <li>On Chrome I've clicked on the locker &gt; certificates &gt; Details &gt; copy in a file &gt; base 64 &gt; certif.cer</li>
  </ol>
  <p>My code is :</p>
  <pre><code>test = requests.get('https://confidential.xx/', verify='certif.cer')
  </code></pre>
  <p>And the error is :</p>
  <blockquote>
  <p>File
  &quot;C:\Users\xxxxx\Downloads\WinPython\WPy64-3850\python-3.8.5.amd64\lib\site-packages\requests\adapters.py&quot;,
  line 514, in send
  raise SSLError(e, request=request)</p>
  <p>SSLError: HTTPSConnectionPool(host='xxxxx',
  port=443): Max retries exceeded with url: / (Caused by
  SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED]
  certificate verify failed: self signed certificate in certificate
  chain (_ssl.c:1123)')))</p>
  </blockquote>
  <p>I don't wanna use verify=False which works but not securised.</p>
  <p>I have tried with and without the proxies, same error...</p>
  <p>I need to make this working, how make this code working please ?</p>
