CURLOPT_CAPATH(3) libcurl 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.
The default value for this can be figured out with CURLINFO_CAPATH(3).
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.
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
