## What it is
SSH.NET is a Secure Shell (SSH-2) client library for .NET, optimized for parallelism. It provides SSH command execution, SFTP and SCP file transfer, port forwarding, and interactive shell support with multiple authentication methods.

## Use cases
- run remote commands over ssh from c#
- upload and download files via sftp in .net
- scp file transfer from a dotnet application
- set up ssh port forwarding in c#
- connect to ssh through a socks or http proxy
- automate remote server tasks from .net

## When to choose
- you need SSH, SFTP, or SCP functionality in a .NET application
- you need async/sync SSH operations with good parallelism
- you need proxy support or multi-factor authentication for SSH connections

## When to avoid
- you need an SSH server implementation rather than a client
- you are not working in the .NET ecosystem
- you need a command-line ssh tool rather than a programmable library

## Facets
- artifact type: library
- maturity: stable
- function: ssh, networking, cryptography, file-upload, http-client
- domain: networking, security, developer-tools, files
- platform: dotnet, cross-platform
- tags: sftp, scp, port-forwarding, ssh-client, secure-shell
