title: Adding server certificates to CA_BUNDLE in python
body: <p>I'm using requests to communicate with remote server over https. At the moment I'm not verifying SSL certificate and I'd like to fix that.</p>
  
  <p>Within requests documentation, I've found that:</p>
  
  <blockquote>
    <p>You can pass verify the path to a CA_BUNDLE file with certificates of
    trusted CAs. This list of trusted CAs can also be specified through
    the REQUESTS_CA_BUNDLE environment variable.</p>
  </blockquote>
  
  <p>I don't want to use system's certs, but to generate my own store.</p>
  
  <p>So far I'm grabbing server certificate with ssl.get_server_certificate(addr), but I don't know how to create my own store and add it there.</p>
