我正在尝试使用SSH密钥验证方法通过PHP脚本连接到SFTP服务器。
我的PHP代码是：
<?php
$host = 'my_host';
$port = 22;
$conn = ssh2_connect($host, $port, array('hostkey'=>'ssh-rsa'));
$username = 'my_user';
$pub_key = 'c:/UserKeys/pub_key.pub';
$pri_key = 'c:/UserKeys/priv_key';
ssh2_auth_pubkey_file($conn, $username, $pub_key, $pri_key);
?>
我总是收到以下错误消息： Warning: ssh2_auth_pubkey_file(): Authentication failed for my_user using public key: Invalid key data, not base64 encoded in 。

我正在Internet上查找，但无法使脚本正常工作。
有人可以帮我吗？
