CURLOPT_SSLKEYTYPE(3)curl_easy_setopt optionCURLOPT_SSLKEYTYPE(3)

NAME

     CURLOPT_SSLKEYTYPE - set type of the private key file

SYNOPSIS

     #include <curl/curl.h>

     CURLcode curl_easy_setopt(CURL *handle,  CURLOPT_SSLKEYTYPE,
     char *type);

DESCRIPTION

     Pass a pointer to a zero terminated string as parameter. The
     string  should  be the format of your private key. Supported
     formats are "PEM", "DER" and "ENG".

     The format "ENG" enables you to load the private key from  a
     crypto  engine. In this case CURLOPT_SSLKEY(3) is used as an
     identifier passed to the engine. You have to set the  crypto
     engine  with  CURLOPT_SSLENGINE(3).   "DER"  format key file
     currently does not work because of a bug in OpenSSL.

     The application does not have  to  keep  the  string  around
     after setting this option.

DEFAULT

     "PEM"

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_SSLKEYTYPE, "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.
