.TH CURLOPT_CAPATH 3 "17 Jun 2014" libcurl libcurl
|
||
|
|
.SH NAME
|
||
|
|
CURLOPT_CAPATH \- directory holding CA certificates
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAPATH, char *capath);
|
||
|
|
.fi
|
||
|
|
.SH 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 combination with the
|
||
|
|
\fICURLOPT_SSL_VERIFYPEER(3)\fP option.
|
||
|
|
|
||
|
|
The \fICURLOPT_CAPATH(3)\fP 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 \fICURLINFO_CAPATH(3)\fP.
|
||
|
|
.SH DEFAULT
|
||
|
|
A default path detected at build time.
|
||
|
|
.SH PROTOCOLS
|
||
|
|
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
|
||
|
|
.SH EXAMPLE
|
||
|
|
.nf
|
||
|
|
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);
|
||
|
|
}
|
||

}

|
||
|
|
