NAME

CURLOPT_SSLKEY - specify private keyfile for TLS and SSL client cert  

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLKEY, char *keyfile);  

DESCRIPTION

Pass a pointer to a zero terminated string as parameter. The string should be the file name of your private key. The default format is "PEM" and can be changed with CURLOPT_SSLKEYTYPE(3).

(iOS and Mac OS X only) This option is ignored if curl was built against Secure Transport. Secure Transport expects the private key to be already present in the keychain or PKCS#12 file containing the certificate.

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

DEFAULT

NULL  

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_SSLCERT, "client.pem");
  curl_easy_setopt(curl, CURLOPT_SSLKEY, "key.pem");
  curl_easy_setopt(curl, CURLOPT_KEYPASSWD, "s3cret");
  ret = curl_easy_perform(curl);
  curl_easy_cleanup(curl);
}

 

AVAILABILITY

If built TLS enabled.  

RETURN VALUE

Returns CURLE_OK if TLS is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
