Question

我想使用RSA密钥通过ssh与debian系统建立远程连接，我需要在C＃中生成这些RSA密钥。

我已使用充气城堡以以下方式生成RSA密钥：

using (var rsa = new RSACryptoServiceProvider(2048))
{
    try
    {
       RsaKeyPairGenerator r = new RsaKeyPairGenerator();
       r.Init(new KeyGenerationParameters(new SecureRandom(), 2048));
       AsymmetricCipherKeyPair keys = r.GenerateKeyPair();

       AsymmetricKeyParameter private_key = keys.Private;                    
       AsymmetricKeyParameter public_key = keys.Public;

       TextWriter textWriter = new StringWriter();
       PemWriter pemWriter = new PemWriter(textWriter);
       pemWriter.WriteObject(keys.Private);
       pemWriter.Writer.Flush();

       privateKey = textWriter.ToString();

       textWriter = new StringWriter();
       pemWriter = new PemWriter(textWriter);
       pemWriter.WriteObject(keys.Public);
       pemWriter.Writer.Flush();

       publicKey = textWriter.ToString();

       Console.WriteLine("Private: \n" + privateKey);
       Console.WriteLine("Public: \n" + publicKey);                    
    }
    finally
    { rsa.PersistKeyInCsp = false; } 
}

打印的键如下所示：

打印的密钥似乎是有效的RSA密钥。我试图用它们在一个在线工具中对数据进行签名和验证，并且它起作用了。但是，当我尝试使用这些密钥建立ssh连接时，它不起作用，并提示我输入密码。

然后我将私钥保存在文件中，并使用ssh-keygen打印公钥：

ssh-keygen -y -e -f privateKey.pem

输出与c＃公钥不同：

  ----结束SSH2公钥----

如果我使用ssh-keygen的此输出和c＃私钥建立ssh连接，则它起作用。

我假设两个公钥必须是一个公钥和同一公钥的不同表示形式，但是有人可以向我解释为什么它们不同，或者如何调整我的c＃代码以获取与{{1}相同的公钥}？

或者也许总的来说：如果我想在Debian Linux计算机上使用这些密钥进行SSH登录，用C＃生成RSA密钥的一种好方法是什么？

在C＃
