phpseclib - 我可以使用用户名、密钥和密码(不是密钥密码)进行连接吗

Apologies if I have missed this in the documentation but is it possible to connect to an SFTP server with a private key and a password (not a passphrase for my private key).

The examples show username/password, username/key and username/key/key passphrase authentication types.

When connecting via the command line I would get this prompt for my password...

user@x.x.x.x's password:

Hopefully this library can handle this?

Otherwise are there any other PHP based solutions that might support username/key and server password authentication? I'm quite flexible here and can install modules if need be.

EDIT

Thanks for the help so far... I had tried what you mentioned Neubert but this didn't seem to work. And to verify what is necessary to connect to the server I tested this on the command line.
sftp key user@ip - Prompted for password as expected
sftp user@ip - Prompted for password but when entered correctly told I am "authenticated with partial success".

I think the permission on directories and keys should be fine if I can get in using key and then password.

I am starting to think this library doesn't support what I need.

phpseclib supports multi factor authentication. Here's an example of how to do it:

<?php
include('Net/SSH2.php');
include('Crypt/RSA.php')

$rsa = new Crypt_RSA();
$rsa->loadKey(file_get_contents('/path/to/key.pem'));

$ssh = new Net_SSH2('www.domain.tld');
if (!$ssh->login('username', 'pass1', $rsa)) {
    exit('Login failed');
}
// this does the same thing as the above
//if (!$ssh->login($username, 'pass1') && !$ssh->login('username', $rsa)) {
//    exit('Login failed');
//}

echo $ssh->exec('pwd');
echo $ssh->exec('ls -la');
?>

Something to keep in mind, however: a lot of people confuse password protected private keys as being multi factor (password and public key) when in fact it is not. At least not in-so-far as SSH is concerned.
