NAME

       CURLOPT_SSLKEY - 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  null-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.
