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 cer-
       tificate.

       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.
