## What it is
Apache MINA SSHD is a pure-Java library implementing the SSH protocol on both client and server sides, with pluggable I/O back-ends (built-in NIO2, Apache MINA, or Netty). It includes SFTP and SCP subsystems and is intended for embedding SSH support in Java applications rather than replacing Unix SSH tools.

## Use cases
- embed an SSH server in a Java application
- run SFTP file transfers from Java code
- execute remote commands over SSH from a Java program
- add SCP support to a Java service
- implement port forwarding in a Java app
- build a custom SSH daemon with pluggable authentication

## When to choose
- you need programmatic SSH, SFTP, or SCP support inside a JVM application
- you want an embeddable SSH server rather than shelling out to OpenSSH
- you need pluggable network transports like Netty or Apache MINA
- you want an Apache-licensed, actively maintained SSH implementation

## When to avoid
- you just need a command-line SSH client or daemon on Unix - use OpenSSH
- you are not on the JVM and need a native SSH implementation
- you need a lightweight wrapper around the system ssh binary instead of a full protocol implementation

## Facets
