.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 null-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.
|
|
Starting with curl-7.55.0, if both \fICURLOPT_CAINFO(3)\fP and
|
|
\fICURLOPT_CAPATH(3)\fP are unset, NSS-linked libcurl tries to load
|
|
libnssckbi.so, which contains a more comprehensive set of trust information
|
|
than supported by nss-pem, because libnssckbi.so also includes information
|
|
about distrusted certificates.
|
|
|
|
(iOS and macOS) When curl uses Secure Transport this option is supported. If
|
|
the option is not set, then curl will use the certificates in the system and
|
|
user Keychain to verify the peer.
|
|
|
|
(Schannel) This option is supported for Schannel in Windows 7 or later but we
|
|
recommend not using it until Windows 8 since it works better starting then.
|
|
If the option is not set, then curl will use the certificates in the Windows'
|
|
store of root certificates (the default for Schannel).
|
|
|
|
The application does not have to keep the string around after setting this
|
|
option.
|
|
.SH DEFAULT
|
|
Built-in system specific. When curl is built with Secure Transport or
|
|
Schannel, this option is not set by default.
|
|
.SH PROTOCOLS
|
|
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
|
|
.SH EXAMPLE
|
|
.nf
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
|
|
curl_easy_setopt(curl, CURLOPT_CAINFO, "/etc/certs/cabundle.pem");
|
|
ret = curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
.fi
|
|
.SH AVAILABILITY
|
|
For the SSL engines that don't support certificate files the CURLOPT_CAINFO
|
|
option is ignored. Schannel support added in libcurl 7.60.
|
|
.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.
