SSH.NET仅通过私钥进行身份验证（公钥身份验证）

问题描述

仅尝试使用当前SSH.NET库通过用户名和私钥进行身份验证。我无法从用户那里获得密码，所以这是不可能的。

Attempting to authenticate via username and privatekey only using the current SSH.NET library. I cannot get the password from the user so this is out of the question.

这是我现在正在做的事情。

here is what i am doing now.

Renci.SshNet.ConnectionInfo conn =
    new ConnectionInfo(hostName, port, username, new AuthenticationMethod[]
        {
            new PasswordAuthenticationMethod(username, ""),
            new PrivateKeyAuthenticationMethod(username, new PrivateKeyFile[]
                   { new PrivateKeyFile(privateKeyLocation, "") }),
        });

using (var sshClient = new SshClient(conn))
{
    sshClient.Connect();
}

现在，如果我删除了 PasswordAuthenticationMethod AuthenticationMethod [] 数组中的c $ c>我得到了一个异常，因为找不到合适的身份验证方法。如果我尝试这样传递（主机名，端口，用户名，密钥文件2）

Now, if I remove the PasswordAuthenticationMethod from the AuthenticationMethod[] array I get an exception for for no suitable authentication method found. If i attempt to pass in the (hostname, port, username, keyfile2) as such

var keyFile = new PrivateKeyFile(privateKeyLocation);
var keyFile2 = new[] {keyFile};

找不到合适的方法。

似乎如上所述，必须使用 ConnectionInfo 对象，但似乎它会评估 PasswordAuthenticationMethod 并无法登录（因为我没有提供密码）并且从不评估 PrivateKeyAuthMethod ...是这种情况吗？

It seems I have to use the ConnectionInfo object as I outlined above, but it seems that it evaluates the PasswordAuthenticationMethod and cant log in (since i don't provide a password) and never evaluates the PrivateKeyAuthMethod... is this the case? Is there some other way to authenticate with only a username or hostname and private key using SSH.NET lib?

推荐答案

您的问题在这里吗？就是您仍在使用密码，即使密码为空。删除以下行：

Your problem here is that you're still using a password, even though it is blank. Remove this line:

new PasswordAuthenticationMethod(username, ""),

这对我来说很完美：

var pk = new PrivateKeyFile(yourkey);
var keyFiles = new[] { pk };

var methods = new List<AuthenticationMethod>();
methods.Add(new PrivateKeyAuthenticationMethod(UserName, keyFiles));

var con = new ConnectionInfo(HostName, Port, UserName, methods.ToArray());
