CURLOPT_CERTINFO(3)

CURLOPT_CERTINFO(3)        curl_easy_setopt options        CURLOPT_CERTINFO(3)



NAME
       CURLOPT_CERTINFO - request SSL certificate information

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CERTINFO, long certinfo);

DESCRIPTION
       Pass  a  long set to 1 to enable libcurl's certificate chain info gath‐
       erer. With this enabled, libcurl will extract lots of  information  and
       data  about  the  certificates in the certificate chain used in the SSL
       connection. This data may then be  retrieved  after  a  transfer  using
       curl_easy_getinfo(3) and its option CURLINFO_CERTINFO(3).

DEFAULT
       0

PROTOCOLS
       All TLS-based

EXAMPLE
       curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://www.example.com/");

         /* connect to any HTTPS site, trusted or not */
         curl_easy_setopt(curl, CURLOPT_SSL_VERIFYPEER, 0L);
         curl_easy_setopt(curl, CURLOPT_SSL_VERIFYHOST, 0L);

         curl_easy_setopt(curl, CURLOPT_CERTINFO, 1L);

         res = curl_easy_perform(curl);

         if (!res) {
           struct curl_certinfo *ci;
           res = curl_easy_getinfo(curl, CURLINFO_CERTINFO, &ci);

           if (!res) {
             printf("%d certs!\n", ci->num_of_certs);

             for(i = 0; i < ci->num_of_certs; i++) {
               struct curl_slist *slist;

               for(slist = ci->certinfo[i]; slist; slist = slist->next)
                 printf("%s\n", slist->data);
             }
           }
         }
         curl_easy_cleanup(curl);
       }
