CURLOPT_SSH_PRIVATE_KEYFILE explained

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 CURLOPT_KEYPASSWD.

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

DEFAULT

As explained above

PROTOCOLS

EXAMPLE

                   "/home/clarkkent/.ssh/id_rsa");
