wtf is ssh?

The gliderlabs/ssh package lets developers build custom SSH servers in the Go programming language without wrestling with low-level cryptographic details. SSH is the secure protocol normally used to remotely log into servers and run commands. This library makes it straightforward to create your own SSH server that can do whatever you want when someone connects. Under the hood, Go already includes a basic SSH toolkit, but its API is complex and meant for experts. This package wraps that lower-level toolkit with a simpler, higher-level interface. The goal is to make writing an SSH server as easy as writing a basic web server in Go: you define what happens when a session starts, tell the server to listen on a port, and it handles the secure connection mechanics for you. A developer would use this to build tools that accept SSH connections for purposes beyond traditional remote shell access. For example, you could build a chat application accessible via SSH, a custom deployment tool that developers connect to with their existing SSH keys, or a service that delivers information or runs tasks when someone logs in. The project includes an examples directory showing various use cases. The project is still approaching its 1.0 release, with features like non-session channel handlers and a cleanup callback API on the roadmap. The maintainers note that API design is a priority, so they encourage discussing changes before submitting code.
