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

Version NuGet download count Build status

Key Features

  • Execution of SSH command using both synchronous and asynchronous methods
  • SFTP functionality for both synchronous and asynchronous operations
  • SCP functionality
  • Remote, dynamic and local port forwarding
  • Interactive shell/terminal implementation
  • Authentication via publickey, password and keyboard-interactive methods, including multi-factor
  • Connection via SOCKS4, SOCKS5 or HTTP proxy

How to Use

Run a command

using (var client = new SshClient("sftp.foo.com", "guest", new PrivateKeyFile("path/to/my/key")))
{
    client.Connect();
    using SshCommand cmd = client.RunCommand("echo 'Hello World!'");
    Console.WriteLine(cmd.Result); // "Hello World!\n"
}

Upload and list files using SFTP

using (var client = new SftpClient("sftp.foo.com", "guest", "pwd"))
{
    client.Connect();

    using (FileStream fs = File.OpenRead(@"C:\tmp\test-file.txt"))
    {
        client.UploadFile(fs, "/home/guest/test-file.txt");
    }

    foreach (ISftpFile file in client.ListDirectory("/home/guest/"))
    {
        Console.WriteLine($"{file.FullName} {file.LastWriteTime}");
    }
}

Public Key Authentication

SSH.NET supports the following private key formats:

  • RSA in
    • OpenSSL traditional PEM format ("BEGIN RSA PRIVATE KEY")
    • OpenSSL PKCS#8 PEM format ("BEGIN PRIVATE KEY", "BEGIN ENCRYPTED PRIVATE KEY")
    • ssh.com format ("BEGIN SSH2 ENCRYPTED PRIVATE KEY")
    • OpenSSH key format ("BEGIN OPENSSH PRIVATE KEY")
  • DSA in
    • OpenSSL traditional PEM format ("BEGIN DSA PRIVATE KEY")
    • OpenSSL PKCS#8 PEM format ("BEGIN PRIVATE KEY", "BEGIN ENCRYPTED PRIVATE KEY")
    • ssh.com format ("BEGIN SSH2 ENCRYPTED PRIVATE KEY")
  • ECDSA 256/384/521 in
    • OpenSSL traditional PEM format ("BEGIN EC PRIVATE KEY")
    • OpenSSL PKCS#8 PEM format ("BEGIN PRIVATE KEY", "BEGIN ENCRYPTED PRIVATE KEY")
    • OpenSSH key format ("BEGIN OPENSSH PRIVATE KEY")
  • ED25519 in
    • OpenSSL PKCS#8 PEM format ("BEGIN PRIVATE KEY", "BEGIN ENCRYPTED PRIVATE KEY")
    • OpenSSH key format ("BEGIN OPENSSH PRIVATE KEY")

Private keys in OpenSSL traditional PEM format can be encrypted using one of the following cipher methods:

  • DES-EDE3-CBC
  • DES-EDE3-CFB
  • DES-CBC
  • AES-128-CBC
  • AES-192-CBC
  • AES-256-CBC

Private keys in OpenSSL PKCS#8 PEM format can be encrypted using any cipher method BouncyCastle supports.

Private keys in ssh.com format can be encrypted using one of the following cipher methods:

  • 3des-cbc

Private keys in OpenSSH key format can be encrypted using one of the following cipher methods:

  • 3des-cbc
  • aes128-cbc
  • aes192-cbc
  • aes256-cbc
  • aes128-ctr
  • aes192-ctr
  • aes256-ctr
  • aes128-gcm@openssh.com
  • aes256-gcm@openssh.com
