NAME

       CURLOPT_SSLKEY - private key file 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).

       (Windows,  iOS  and  Mac OS X) This option is ignored by Secure Transport and Schannel SSL
       backends because they expect the private key to be already present  in  the  key-chain  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.
