SSH.NET is a Secure Shell (SSH-2) library for .NET, optimized for parallelism.

Version NuGet download count Build status


This project was inspired by Sharp.SSH library which was ported from java and it seems like was not supported for quite some time. This library is a complete rewrite, without any third party dependencies, using parallelism to achieve the best performance possible.


Documentation is hosted at Currently (4/18/2020), the documentation is very sparse. Fortunately, there are a large number of tests that demonstrate usage with working code. If the test for the functionality you would like to see documented is not complete, then you are cordially invited to read the source, Luke, and highly encouraged to generate a pull request for the implementation of the missing test once you figure things out. 🤓

Multi-factor authentication

Establish a SFTP connection using both password and public-key authentication:

var connectionInfo = new ConnectionInfo("",
                                        new PasswordAuthenticationMethod("guest", "pwd"),
                                        new PrivateKeyAuthenticationMethod("rsa.key"));
using (var client = new SftpClient(connectionInfo))

Verify host identify

Establish a SSH connection using user name and password, and reject the connection if the fingerprint of the server does not match the expected fingerprint:

string expectedFingerPrint = "LKOy5LvmtEe17S4lyxVXqvs7uPMy+yF79MQpHeCs/Qo";

using (var client = new SshClient("", "guest", "pwd"))
    client.HostKeyReceived += (sender, e) =>
            e.CanTrust = expectedFingerPrint.Equals(e.FingerPrintSHA256);

Building the library

The library has no special requirements to build, other than an up-to-date .NET SDK. See also
