NAME

CURLINFO_SSL_VERIFYRESULT - get the result of the certificate verification

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SSL_VERIFYRESULT,
                           long *result);

Pass a pointer to a long to receive the result of the server SSL certificate verification that was requested (using the CURLOPT_SSL_VERIFYPEER(3) option).

0 is a positive result. Non-zero is an error.

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    long verifyresult;
    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
    res = curl_easy_perform(curl);
    if(res)
      printf("error: %s\n", curl_easy_strerror(res));
    curl_easy_getinfo(curl, CURLINFO_SSL_VERIFYRESULT, &verifyresult);
    printf("The peer verification said %s\n", verifyresult?
           "BAAAD":"fine");
    curl_easy_cleanup(curl);
  }
}
