SSH.NET

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

Version Build status

Introduction

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.

Features

  • Execution of SSH command using both synchronous and asynchronous methods
  • Return command execution exit status and other information
  • Provide SFTP functionality for both synchronous and asynchronous operations
  • Provides SCP functionality
  • Provide status report for upload and download sftp operations to allow accurate progress bar implementation
  • Remote, dynamic and local port forwarding
  • Shell/Terminal implementation
  • Specify key file pass phrase
  • Use multiple key files to authenticate
  • Supports 3des-cbc, aes128-cbc, aes192-cbc, aes256-cbc, aes128-ctr, aes192-ctr, aes256-ctr, blowfish-cbc, cast128-cbc, arcfour and twofish encryptions
  • Supports publickey, password and keyboard-interactive authentication methods
  • Supports RSA and DSA private key
  • Supports DES-EDE3-CBC, DES-EDE3-CFB, DES-CBC, AES-128-CBC, AES-192-CBC and AES-256-CBC algorithms for private key encryption
  • Supports two-factor or higher authentication
  • Supports SOCKS4, SOCKS5 and HTTP Proxy

Key Exchange Method

SSH.NET supports the following key exchange methods:

  • diffie-hellman-group-exchange-sha256
  • diffie-hellman-group-exchange-sha1
  • diffie-hellman-group14-sha1
  • diffie-hellman-group1-sha1

Message Authentication Code

SSH.NET supports the following MAC algorithms:

  • hmac-md5
  • hmac-md5-96
  • hmac-sha1
  • hmac-sha1-96
  • hmac-sha2-256
  • hmac-sha2-256-96
  • hmac-sha2-512
  • hmac-sha2-512-96
  • hmac-ripemd160
  • hmac-ripemd160@openssh.com

Framework Support

SSH.NET supports the following target frameworks:

  • .NET Framework 3.5
  • .NET Framework 4.0 (and higher)
  • .NET Standard 1.3
  • Silverlight 4
  • Silverlight 5
  • Windows Phone 7.1
  • Windows Phone 8.0
  • Universal Windows Platform 10

Usage

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

var connectionInfo = new ConnectionInfo("sftp.foo.com",
                                        "guest",
                                        new PasswordAuthenticationMethod("guest", "pwd"),
                                        new PrivateKeyAuthenticationMethod("rsa.key"));
using (var client = new SftpClient(connectionInfo))
{
    client.Connect();
}
