(Finish) Implementing SSH in Zig
a project by lmulling
Updated 13 days ago. 5 hacker ♥️. 4 followers.

Description

Following Zig's philosophy of reinventing the wheel -- for the better, a while ago I've started implementing the ssh protocol in it. I've got as far as implementing all of the primitives, keys, certs, and most of the agent protocol -- what I needed at the time. Now, the aim is to finish the implementation.

Current implementation: git.sr.ht/~mulling/zssh

Goals

  • Have a working implementation of the ssh protocol in Zig.
  • Be flexible, as to allow for hacking of the protocol (i.e. testing PQC algorithms).
  • Be agnostic of cryptography libraries (i.e. libcrypto, leancrypto).

      Hi! I saw this project being spoken about on Mastodon. If you haven't seen it, you might be interested in my SSH client and server in Zig. It's unmaintained and a bit scrappy - but, it does work. Hope it's helpful inspiration https://github.com/ringtailsoftware/misshod

        Initially I'd hoped to get further in the implementation but that didn't materialize. Essentially I'm doing a declarative implementation, so you can easy define things outside of the protocol. I haven't found a good way to do this with with the SSH2_MSG* packets and the state machine. But, I'll continue work outside of hackweek.
