CURLOPT_CAPATH3
Directory holding ca certificates
Usage
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAPATH, char *capath);
Overview
Pass a char pointer 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 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.
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.
Examples
int main(void)
{
CURL *curl = curl_easy_init();
if(curl) {
CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
curl_easy_setopt(curl, CURLOPT_CAPATH, "/etc/cert-dir");
res = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
}
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
