CURLOPT_SSLKEY(3)

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 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.
