SSH.NET is a popular, open-source Secure Shell (SSH-2) library for .NET, written entirely in C# and optimized for parallelism and performance. It functions as a fully managed client-side library, allowing developers to safely connect to remote servers, execute automated commands, and securely transfer files without requiring native system dependencies like OpenSSL. Key Features
Command Execution: Run remote shell commands via synchronous or asynchronous methods and easily capture exit statuses or output streams.
SFTP & SCP Support: Transfer files securely using standard Secure Copy Protocol (SCP) or SSH File Transfer Protocol (SFTP), including built-in progress tracking for UI progress bars.
Port Forwarding: Set up remote, local, and dynamic (SOCKS4, SOCKS5, or HTTP proxy) port forwarding tunnels through your application.
Interactive Terminal: Establish a live, interactive shell session to manipulate a remote terminal programmatically.
Multi-Factor Authentication: Authenticate using traditional passwords, keyboard-interactive prompts, single/multiple private key files, or combinations for multi-factor setups. Cryptography & Compatibility
The library is continuously updated and maintains compatibility across modern .NET (.NET 6/8/9), .NET Standard, and legacy .NET Framework environments, meaning it runs natively across Windows, Linux, and macOS.
