Subject: - Introducing CURLOPT_CERTINFO and the corresponding
 CURLINFO_CERTINFO. By   enabling this feature with CURLOPT_CERTINFO for a
 request using SSL (HTTPS   or FTPS), libcurl will gather lots of server
 certificate info and that info   can then get extracted by a client after the
 request has completed with   curl_easy_getinfo()'s CURLINFO_CERTINFO option.
 Linus Nielsen Feltzing   helped me test and smoothen out this feature.

  Unfortunately, this feature currently only works with libcurl built to use
  OpenSSL.

  This feature was sponsored by networking4all.com - thanks!
