NAME¶

CURLOPT_SSH_AUTH_TYPES - 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.

DEFAULT¶

CURLSSH_AUTH_ANY (all available)

PROTOCOLS¶

This functionality affects scp and sftp

EXAMPLE¶

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_AUTH_TYPES,


                     CURLSSH_AUTH_PUBLICKEY | CURLSSH_AUTH_KEYBOARD);


    res = curl_easy_perform(curl);


    curl_easy_cleanup(curl);


  }
}
