phpseclib OpenSSH或PuTTYgen密钥生成

Question

我正在尝试生成私有和公共RSA密钥，以便我可以将其传递给供应商并连接到他们的SFTP服务器。为此，我使用phpseclib，但无论我创建什么密钥，供应商都会收到错误消息，指出输入的SSH密钥无效且不受支持。请输入有效密钥(OpenSSH或PuTTYgen)

我试过了：

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

$rsa = new Crypt_RSA();

$rsa->setPrivateKeyFormat(CRYPT_RSA_PRIVATE_FORMAT_PUTTY);
$rsa->setPublicKeyFormat(CRYPT_RSA_PUBLIC_FORMAT_OPENSSH);

//define('CRYPT_RSA_EXPONENT', 65537);
//define('CRYPT_RSA_SMALLEST_PRIME', 982451653); // makes it so multi-prime RSA is used
extract($rsa->createKey()); // == $rsa->createKey(1024) where 1024 is the key size

echo $privatekey;
echo "\n\n\n";
echo $publickey;
?>

以下是生成密钥的示例：

PuTTY-User-Key-File-2: ssh-rsa
Encryption: none

我做错了什么？
