WISH: List public keys of other pico.sh users => encrypt and sign messages

[HenrikBengtsson]

Just like GitHub allows us to list public keys of other users;

$ curl -s https://github.com/bob.keys
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIFhj0e/TthyrXlaTTSyd6B7/J4XpPwAHruiOJAnDOk52
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAICzeSiOPuhuLSqzS9ljy8SlptJjXrlU16O1dQPQkOT0l
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAILZzs/Uawuom1WUvl24j7LryC8/C2+NBNkwJJ41TH7T3
ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEAv91jFaTvWprx3mo07uDSB5jI0Fzyu8xOuqgz9HGmu+UyvqfpGD33dB9Di+hx+Ug/e49KLgRWr7EMKpHg8vMzb7C00k0mt7tALS4pDBrqGOTd9IM3SAmwR0qm2ynH7m0+JIrLrxF31TUhG/Z520gEeDnAS/dOlmvS+CasopVgkXfQa1gyN9zVYSTsSh6anhKxjCk6TvWVoiZXBAf8khs6NaSAyicTQu94F8YXWJAjSJEPaPzyM5RVK7GvoyOYhvUwUfGOgj+FJ9/p+Mii60mRDegtfFO1JHVUJbT6vhDgx/jRs5vtVvEAP7sfUyLp0G9MzsHSNJRTQ8Y0hq5paHb6Kw==

It would be useful if one could list public keys of another pico.sh user, e.g.

$ ssh pico.sh keys bob

Knowing another user's public key would allow you to send them encrypted messages that only they can decrypt. You could also sign your own messages and they could validate with your public keys on pico.sh that you've sent it.

FWIW, the default could be to list your own keys, e.g.

$ ssh pico.sh keys

Hi! This is a good idea, contributions are welcome! The pico cli code is here: https://github.com/picosh/pico/blob/main/pkg/apps/pico/cli.go#L163

I'm a rookie when it comes to Go, but could give it a go when I find time. Maybe my first task should be to:

• spin up the current implementation as a localhost:4321 service to confirm that ssh http://127.0.0.1:4321 provides all the regular functions

Q1. Is there a pre-built binary for this, or a Linux container?

Q2. Are there instructions for building "whatever I need here" from source? I see there's a Makefile in the repo, but I don't know if that applies here - is there a make rule somewhere for building from source?

There's a linux container: https://github.com/picosh/pico/pkgs/container/pico%2Fpico-ssh

When developing locally we run go run ./cmd/pico/ssh

The main thing you need besides the go binary is to setup postgresql:
