libriscv looks amazing but its's much larger. It says "Less than 40kB total memory usage". My first version (unpublished) of uvm32 was called uvm80 and emulated a Zilog Z80 CPU. My aim is to have a safe, embeddable sandbox for any device, rather than the best performance.

I use SSH every day. I login to remote machines, push code changes to github and scp files. Like many programmers, I know how to use SSH to get things done but had never looked deeper to understand the protocol itself.

I recently wrote a minimal SSH client to help demystify the protocol. In this post, I'll explain some of the core concepts to help anyone else doing the same. This will be a 10,000ft overview with references to some interesting parts - not an implementation guide.
