base on SSH.NET is a Secure Shell (SSH) library for .NET, optimized for parallelism.  SSH.NET ======= SSH.NET is a Secure Shell (SSH-2) library for .NET, optimized for parallelism. [](https://www.nuget.org/packages/SSH.NET) [](https://www.nuget.org/packages/SSH.NET)  ## Key Features * Execution of SSH commands 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 public key, password and keyboard-interactive methods, including multi-factor * Connection via SOCKS4, SOCKS5 or HTTP proxy ## How to Use ### Run a command ```cs 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 ```cs 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}"); } } ``` ## Main Types The main types provided by this library are: * [Renci.SshNet.SshClient](https://sshnet.github.io/SSH.NET/api/Renci.SshNet.SshClient.html) * [Renci.SshNet.SftpClient](https://sshnet.github.io/SSH.NET/api/Renci.SshNet.SftpClient.html) * [Renci.SshNet.PrivateKeyFile](https://sshnet.github.io/SSH.NET/api/Renci.SshNet.PrivateKeyFile.html) * [Renci.SshNet.SshCommand](https://sshnet.github.io/SSH.NET/api/Renci.SshNet.SshCommand.html) * [Renci.SshNet.ForwardedPort](https://sshnet.github.io/SSH.NET/api/Renci.SshNet.ForwardedPort.html) * [Renci.SshNet.ShellStream](https://sshnet.github.io/SSH.NET/api/Renci.SshNet.ShellStream.html) ## Additional Documentation * [Further examples](https://sshnet.github.io/SSH.NET/examples.html) * [Logging](https://sshnet.github.io/SSH.NET/logging.html) * [API browser](https://sshnet.github.io/SSH.NET/api/Renci.SshNet.html) ## Encryption Methods **SSH.NET** supports the following encryption methods: * aes128-ctr * aes192-ctr * aes256-ctr * aes128-gcm<span></span>@openssh.com * aes256-gcm<span></span>@openssh.com * chacha20-poly1305<span></span>@openssh.com * aes128-cbc * aes192-cbc * aes256-cbc * 3des-cbc ## Key Exchange Methods **SSH.NET** supports the following key exchange methods: * mlkem768x25519-sha256 * sntrup761x25519-sha512 * sntrup761x25519-sha512<span></span>@openssh.com * curve25519-sha256 * curve25519-sha256<span></span>@libssh.org * ecdh-sha2-nistp256 * ecdh-sha2-nistp384 * ecdh-sha2-nistp521 * diffie-hellman-group-exchange-sha256 * diffie-hellman-group-exchange-sha1 * diffie-hellman-group16-sha512 * diffie-hellman-group14-sha256 * diffie-hellman-group14-sha1 * diffie-hellman-group1-sha1 ## 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") * PuTTY private key format ("PuTTY-User-Key-File-2", "PuTTY-User-Key-File-3") * 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") * PuTTY private key format ("PuTTY-User-Key-File-2", "PuTTY-User-Key-File-3") * ED25519 in * OpenSSL PKCS#8 PEM format ("BEGIN PRIVATE KEY", "BEGIN ENCRYPTED PRIVATE KEY") * OpenSSH key format ("BEGIN OPENSSH PRIVATE KEY") * PuTTY private key format ("PuTTY-User-Key-File-2", "PuTTY-User-Key-File-3") Private keys in OpenSSL traditional PEM format can be encrypted using one of the following cipher methods: * DES-EDE3-CBC * DES-EDE3-CFB * 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.

See also [CONTRIBUTING.md](https://github.com/sshnet/SSH.NET/blob/develop/CONTRIBUTING.md). ## Using Pre-Release NuGet Packages Pre-release NuGet packages are published from the `develop` branch to the [GitHub NuGet Registry](https://github.com/sshnet/SSH.NET/pkgs/nuget/SSH.NET). In order to pull packages from the registry, create a Personal Access Token with the `read:packages` permissions. Then add a package source for SSH.NET: ``` dotnet nuget add source --name SSH.NET --username <username> --password <personalaccesstoken> https://nuget.pkg.github.com/sshnet/index.json ``` Note: you may have to add `--store-password-in-clear-text` on non-Windows platforms. Then you can add the the package as described [here](https://github.com/sshnet/SSH.NET/pkgs/nuget/SSH.NET). ## Supporting SSH.NET Do you or your company rely on **SSH.NET** in your projects?
