CURLOPT_SSH_PRIVATE_KEYFILE(3)                        curl_easy_setopt options

NAME
       CURLOPT_SSH_PRIVATE_KEYFILE - set private key file for SSH auth

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSH_PRIVATE_KEYFILE,
                                 char *filename);

DESCRIPTION
       Pass a char * pointing to a filename for your private key. If not used,
       libcurl defaults to $HOME/.ssh/id_dsa if the HOME environment variable
       is set, and just "id_dsa" in the current directory if HOME is not set.

       If the file is password-protected, set the password with
       _KEYPASSWD&section=3">CURLOPT_KEYPASSWD(3).

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

DEFAULT
       As explained above

PROTOCOLS
       SFTP and SCP

EXAMPLE
       CURL *curl = curl_easy_init();

         curl_easy_setopt(curl, CURLOPT_URL, "sftp://example.com/file");
         curl_easy_setopt(curl, CURLOPT_SSH_PRIVATE_KEYFILE,
                          "/home/clarkkent/.ssh/id_rsa");
         curl_easy_setopt(curl, CURLOPT_KEYPASSWD, "password");
