NAME

CURLOPT_PROXY_CAPATH - specify directory holding proxy CA certificates  

SYNOPSIS

#include <curl/curl.h>

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

DESCRIPTION

Pass a char * to a zero terminated string naming a directory holding multiple CA certificates to verify the HTTPS proxy with. If libcurl is built against OpenSSL, the certificate directory must be prepared using the openssl c_rehash utility. This makes sense only when CURLOPT_PROXY_SSL_VERIFYPEER(3) is enabled (which it is by default).

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

DEFAULT

NULL  

PROTOCOLS

Everything used over an HTTPS proxy  

EXAMPLE

CURL *curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
  /* using a HTTPS proxy */
  curl_easy_setopt(curl, CURLOPT_PROXY, "https://localhost:443");
  curl_easy_setopt(curl, CURLOPT_PROXY_CAPATH, "/etc/cert-dir");
  ret = curl_easy_perform(curl);
  curl_easy_cleanup(curl);
}

 

AVAILABILITY

Added in 7.52.0

This option is supported by the OpenSSL, GnuTLS and PolarSSL 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
