ssh2_auth_hostbased_file --  Authenticate using a public hostkey


bool ssh2_auth_hostbased_file ( resource session, string username, string hostname, string pubkeyfile, string privkeyfile [, string passphrase [, string local_username]] )

Authenticate using a public hostkey read from a file. If privkeyfile is encrypted (which it should be), the passphrase must be provided. If local_username is omitted, then the value for username will be used for it.

Example 1. Authentication using a public hostkey

= ssh2_connect('', 22, array('hostkey'=>'ssh-rsa'));

if (
ssh2_auth_hostbased_file($connection, 'remoteusername', '',
'/usr/local/etc/hostkey_rsa', 'secret',
'localusername')) {
"Public Key Hostbased Authentication Successful\n";
} else {
'Public Key Hostbased Authentication Failed');

Note: ssh2_auth_hostbased_file() requires libssh2 >= 0.7 and PHP/SSH2 >= 0.7
