SSH.NET Authenticate via private key only (public key authentication)

Question

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.

Answer 1

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

new PasswordAuthenticationMethod(username, ""), 

This works perfectly for me:

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

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

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