CURLOPT_CAPATH (3)

Name

CURLOPT_CAPATH - specify directory holding CA certificates

Synopsis

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAPATH, char *capath);

Description

CURLOPT_CAPATH(3)          curl_easy_setopt options          CURLOPT_CAPATH(3)



NAME
       CURLOPT_CAPATH - specify directory holding CA certificates

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAPATH, char *capath);

DESCRIPTION
       Pass  a  char  * to a zero terminated string naming a directory holding
       multiple CA certificates to verify the peer with. If libcurl  is  built
       against  OpenSSL,  the certificate directory must be prepared using the
       openssl c_rehash utility.  This makes sense only when used in  combina-
       tion with the CURLOPT_SSL_VERIFYPEER(3) option.

       The  CURLOPT_CAPATH(3) function apparently does not work in Windows due
       to some limitation in openssl.

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

DEFAULT
       NULL

PROTOCOLS
       All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.

EXAMPLE
       CURL *curl = curl_easy_init();
       if(curl) {
         curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
         curl_easy_setopt(curl, CURLOPT_CAPATH, "/etc/cert-dir");
         ret = curl_easy_perform(curl);
         curl_easy_cleanup(curl);
       }

AVAILABILITY
       This  option  is supported by the OpenSSL, GnuTLS, PolarSSL and mbedTLS
       (since 7.56.0) backends. The NSS backend provides the option  only  for
       backward compatibility.

RETURN VALUE
       CURLE_OK if supported; or an error such as:

       CURLE_NOT_BUILT_IN - Not supported by the SSL backend

       CURLE_UNKNOWN_OPTION

       CURLE_OUT_OF_MEMORY
