CURLOPT_CAINFO

Section: curl_easy_setopt options (3)
Updated: May 27, 2017
Index Return to Main Contents

 

NAME

CURLOPT_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 module (libnsspem.so) needs to be available for this option to work properly. Starting with curl-7.55.0, if both CURLOPT_CAINFO(3) and CURLOPT_CAPATH(3) 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 only) If curl is built against Secure Transport, then this option is supported for backward compatibility with other SSL engines, but it should not be set. If the option is not set, then curl will use the certificates in the system and user Keychain to verify the peer, which is the preferred method of verifying the peer's certificate chain.

The application does not have to keep the string around after setting this option.  

DEFAULT

Built-in system specific  

PROTOCOLS

All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.  

EXAMPLE

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);
}
 

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  

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.
