CURLOPT_CAPATH(3) curl_easy_setopt options CURLOPT_CAPATH(3)
NAME
CURLOPT_CAPATH - 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 null-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
A default path detected at build time.
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 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
