Introducing SwiftNIO SSH

I am delighted to introduce a new open source project for the Swift Server ecosystem, SwiftNIO SSH. Distributed as a Swift package, SwiftNIO SSH is designed to enable Swift developers to interact with the SSH network protocol.

SwiftNIO SSH is a new open-source Swift package for the Swift Server ecosystem, providing a programmatic implementation of the SSHv2 protocol for building custom SSH clients and servers.

It supports session channels for executing commands or shells, direct and reverse TCP port forwarding, modern cryptographic primitives like Ed25519 and AES-GCM, and user authentication via asynchronous delegate protocols. Built on SwiftNIO, it uses a NIOSSHHandler to manage the multiplexed SSH protocol, creating child channels for ordered data flow, encapsulated as SSHChannelData.

Designed for flexibility, it enables innovative use cases like interactive interpreters or chat servers, while integrating seamlessly with SwiftNIO and Swift Crypto across supported platforms.
