So changing them after the connection is made still allows libcurl to reuse the existing connections. Reported-by: Bigtang on hackerone Closes #22211

# NAME
|
|
|
|
CURLOPT_SSH_PUBLIC_KEYFILE - public key file for SSH auth
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSH_PUBLIC_KEYFILE,
|
|
char *filename);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a char pointer pointing to a *filename* for your public key. If not used,
|
|
libcurl defaults to **$HOME/.ssh/id_dsa.pub** if the HOME environment variable
|
|
is set, and "id_dsa.pub" in the current directory if HOME is not set.
|
|
|
|
If NULL (or an empty string) is passed to this option, libcurl passes no
|
|
public key to the SSH library, which then rather derives it from the private
|
|
key. If the SSH library cannot derive the public key from the private one and
|
|
no public one is provided, the transfer fails.
|
|
|
|
The application does not have to keep the string around after setting this
|
|
option.
|
|
|
|
This option is used to set up a new connection only. The public key is used
|
|
when libcurl establishes a new SSH connection; once that connection has been
|
|
successfully set up and verified, it is deemed vetted and may be reused by
|
|
libcurl even if this option is changed.

# EXAMPLE

|
|
{
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
CURLcode result;
|
|
curl_easy_setopt(curl, CURLOPT_URL, "sftp://example.com/file");
|
|
curl_easy_setopt(curl, CURLOPT_SSH_PUBLIC_KEYFILE,
|
|
"/home/clarkkent/.ssh/id_rsa.pub");
|
|
result = curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
|
|
}
