hi,here's the code

string cerpath = System.Environment.CurrentDirectory + @"\certs\" + Configs.CertFileName;

SshClient sc = new SshClient(host, username, new PrivateKeyFile(cerpath, Configs.CertPassPhrase)); //exception occurs here


var scom = sc.RunCommand(command);

return scom.Result;


and here's the stack trace:

Looks like you are trying to load an (for this library) invalid privatekey.

What kind of key you are trying to load? How was this key created?

Have you tried other keys?

@wanglvhang: I got the same error because I used the wrong passphrase.
