CURLOPT_SSH_PRIVATE_KEYFILE - Man Page

private key file for SSH auth

Synopsis

#include <curl/curl.h>

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

Pass a char * 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 just "id_rsa" or "id_dsa" in the current directory if HOME is not set.

If the file is password-protected, set the password with 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

                   "/home/clarkkent/.ssh/id_rsa");
  curl_easy_setopt(curl, CURLOPT_KEYPASSWD, "password");
  ret = curl_easy_perform(curl);
  curl_easy_cleanup(curl);
