CURLOPT_SSLKEY(3)          curl_easy_setopt options          CURLOPT_SSLKEY(3)

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
       TODO

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.
