## What it is
Russh is a low-level, Tokio-based SSH2 client and server library for Rust, forked from Thrussh. It supports a wide range of ciphers, key exchanges, MACs, authentication methods, port and UNIX socket forwarding, SFTP, and OpenSSH extensions.

## Use cases
- implement an SSH client in Rust
- build an SSH server in Rust
- run remote commands over SSH programmatically
- set up local and remote port forwarding
- transfer files with SFTP from Rust
- add SSH agent forwarding to an app

## When to choose
- you need async SSH client or server functionality in a Tokio-based Rust project
- you need broad algorithm support including legacy ciphers and post-quantum key exchange
- you want panic-safe, memory-conscious SSH implementation

## When to avoid
- you just need a CLI ssh command rather than a library
- you need a high-level wrapper with simple one-call APIs
- your project is not in Rust

## Facets
- artifact type: library
- maturity: active
- function: http-client, networking, security, cryptography, sdk
- domain: networking, security, developer-tools, backend
- platform: rust, cross-platform, windows
- tags: ssh, ssh-client, ssh-server, tokio, async, sftp, port-forwarding, thrussh-fork, linux, macos
