CURLOPT_ISSUERCERT(3)

CURLOPT_ISSUERCERT(3)      curl_easy_setopt options      CURLOPT_ISSUERCERT(3)



NAME
       CURLOPT_ISSUERCERT - issuer SSL certificate filename

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_ISSUERCERT, char *file);

DESCRIPTION
       Pass  a  char  * to a null-terminated string naming a file holding a CA
       certificate in PEM format. If the option is set,  an  additional  check
       against  the  peer  certificate  is  performed  to verify the issuer is
       indeed the one associated with the certificate provided by the  option.
       This  additional  check is useful in multi-level PKI where one needs to
       enforce that the peer certificate is from  a  specific  branch  of  the
       tree.

       This  option  makes  sense  only when used in combination with the CUR‐
       LOPT_SSL_VERIFYPEER(3) option. Otherwise, the result of  the  check  is
       not considered as failure.

       A  specific  error  code  (CURLE_SSL_ISSUER_ERROR)  is defined with the
       option, which is returned if the  setup  of  the  SSL/TLS  session  has
       failed  due  to  a  mismatch  with the issuer of peer certificate (CUR‐
       LOPT_SSL_VERIFYPEER(3) has to be set too for the check to fail). (Added
       in 7.19.0)

       The  application  does not have to keep the string around after setting
       this option.

DEFAULT
       NULL

PROTOCOLS
       All TLS-based protocols

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
         curl_easy_setopt(curl, CURLOPT_ISSUERCERT, "/etc/certs/cacert.pem");
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

AVAILABILITY
       If built TLS enabled

RETURN VALUE
       Returns CURLE_OK if the option is  supported,  CURLE_UNKNOWN_OPTION  if
       not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
