| .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, POP3S, SMTPS etc. |
| .SH EXAMPLE |
| TODO |
| .SH AVAILABILITY |
| For SSL engines that don't support certificate files the CURLOPT_CAINFO option |
| is ignored. Refer to https://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. |
| .SH "SEE ALSO" |
| .BR CURLOPT_CAPATH "(3), " |
