- .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
- If built TLS enabled
- .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_SSL_VERIFYPEER "(3), " CURLOPT_SSL_VERIFYHOST "(3), "
