CURLOPT_CAPATH(3) 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 combination with the CURLOPT_SSL_VERIFYPEER(3) option.

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

DEFAULT

NULL

PROTOCOLS

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

EXAMPLE

TODO

AVAILABILITY

This option is supported by the OpenSSL, GnuTLS and PolarSSL backends. The NSS backend provides the option only for backward compatibility.

RETURN VALUE

Returns CURLE_OK if TLS enabled, and CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
