## What it is
AsyncSSH is a Python library providing asynchronous client and server implementations of the SSHv2 protocol, including SFTP and SCP, built on Python's asyncio framework. It supports a wide range of SSH features such as port forwarding, multiple authentication methods, public keys, certificates, and ssh-agent integration.

## Use cases
- run remote commands over ssh from python asynchronously
- implement an ssh server in python
- transfer files with sftp or scp programmatically
- set up local or remote port forwarding over ssh
- automate ssh-based tasks with asyncio
- authenticate with public keys, passwords, or FIDO2 security keys

## When to choose
- you need SSH client or server functionality in an asyncio-based Python application
- you need SFTP/SCP file transfer with async I/O
- you need advanced SSH features like forwarding, agent support, or X.509 certificates

## When to avoid
- you need a simple blocking SSH client without asyncio
- you are not using Python 3.10+
- you need a command-line SSH tool rather than a library

## Facets
- artifact type: library
