Remove the PROTOCOLS section from the source files completely and instead generate them based on the header data in the curldown files. It also generates TLS backend information for options marked for TLS as protocol. Closes #13175

# NAME
|
|
|
|
CURLOPT_SSH_PRIVATE_KEYFILE - private key file for SSH auth
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#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
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
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);
|
|
}
|
|
}
