CURLOPT_CAINFO(3) curl_easy_setopt options CURLOPT_CAINFO(3)NAMECURLOPT_CAINFO - path to Certificate Authority (CA) bundle
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAINFO, char *path);
DESCRIPTION
Pass a char * to a zero terminated string naming a file holding one or
more certificates to verify the peer with.
If CURLOPT_SSL_VERIFYPEER(3) is zero and you avoid verifying the
server's certificate, CURLOPT_CAINFO(3) 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 mod‐
ule (libnsspem.so) needs to be available for this option to work prop‐
erly.
DEFAULT
Built-in system specific
PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
EXAMPLE
TODO
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
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.
