CURLOPT_SSH_PRIVATE_KEYFILE(3) Introduction to Library Functions

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

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