I don't know, it's a very basic tool that's good to have in a tool like nak, I wrote mostly it because I wanted a shared pubkey with nostr:npub10000003zmk89narqpczy4ff6rnuht2wu05na7kpnh3mak7z2tqzsv8vwqk that could be the "owner" of the https://github.com/fiatjaf/window.nostr.js and other git repos on we'll be hosting on https://git.njump.me instead of on GitHub soon (est 18 months).
