CURLOPT_SSH_PUBLIC_KEYFILE(3)

NAME
CURLOPT_SSH_PUBLIC_KEYFILE - set public key file for SSH auth

SYNOPSIS
#include <curl/curl.h>

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

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

If NULL (or an empty string) is passed, libcurl will pass no public key to libssh2, which then tries to compute it from the private key. This is known to work with libssh2 1.4.0+ linked against OpenSSL.

The application does not have to keep the string around after setting this option.

DEFAULT
NULL

PROTOCOLS
SFTP and SCP

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

AVAILABILITY
The "" trick was added in 7.26.0

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.
