NAME

CURLOPT_SSH_AUTH_TYPES - set desired auth types for SFTP and SCP  

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSH_AUTH_TYPES, long bitmask);  

DESCRIPTION

Pass a long set to a bitmask consisting of one or more of CURLSSH_AUTH_PUBLICKEY, CURLSSH_AUTH_PASSWORD, CURLSSH_AUTH_HOST, CURLSSH_AUTH_KEYBOARD and CURLSSH_AUTH_AGENT.

Set CURLSSH_AUTH_ANY to let libcurl pick a suitable one. Currently CURLSSH_AUTH_HOST has no effect. If CURLSSH_AUTH_AGENT is used, libcurl attempts to connect to ssh-agent or pageant and let the agent attempt the authentication.

                   CURLSSH_AUTH_PUBLICKEY | CURLSSH_AUTH_KEYBOARD);
  ret = curl_easy_perform(curl);
  curl_easy_cleanup(curl);
}
