CURLOPT_SSH_PRIVATE_KEYFILE3
Private key file for ssh auth
Usage
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSH_PRIVATE_KEYFILE,
char *filename);
Overview
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
SFTP and SCP
Examples
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);
}
}
Return value
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
