NAME

       CURLOPT_SSH_PRIVATE_KEYFILE - 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  pointer  pointing  to a filename for your private key. If not used, libcurl
       defaults to $HOME/.ssh/id_rsa or $HOME/.ssh/id_dsa if the  HOME  environment  variable  is
       set, and in the current directory if HOME is not set.

       If the file is password-protected, set the password with CURLOPT_KEYPASSWD(3).

       The  SSH  library  derives  the public key from this private key when possible. If the SSH
       library cannot derive the public key from the private one and no public  one  is  provided
       with CURLOPT_SSH_PUBLIC_KEYFILE(3), the transfer fails.

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

DEFAULT

       As explained above

PROTOCOLS

       This functionality affects scp and sftp

EXAMPLE

       int main(void)

         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           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");
           res = curl_easy_perform(curl);
           curl_easy_cleanup(curl);
         }
       }
