.TH CURLOPT_CAINFO 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_CAINFO \- path to Certificate Authority (CA) bundle
.SH SYNOPSIS
#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAINFO, char *path);
.SH DESCRIPTION
Pass a char * to a zero terminated string naming a file holding one or more
certificates to verify the peer with.

If \fICURLOPT_SSL_VERIFYPEER(3)\fP is zero and you avoid verifying the
server's certificate, \fICURLOPT_CAINFO(3)\fP need not even indicate an
accessible file.

This option is by default set to the system path where libcurl's cacert bundle
is assumed to be stored, as established at build time.

If curl is built against the NSS SSL library, the NSS PEM PKCS#11 module
(libnsspem.so) needs to be available for this option to work properly.
.SH DEFAULT
Built-in system specific
.SH PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3, SMTPS etc.
.SH EXAMPLE
TODO
.SH AVAILABILITY
For SSL engines that don't support certificate files the CURLOPT_CAINFO option
is ignored. Refer to http://curl.haxx.se/docs/ssl-compared.html
.SH RETURN VALUE
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or
CURLE_OUT_OF_MEMORY if there was insufficient heap space.
