Very good. I have a specific way to derive the key using PBKDF2, where you don't need anything to do with Nostr - no NIP07, nothing.

See deriveKeys here:
https://github.com/jooray/anonmicroblog/blob/main/webposter/src/index.js

This way it's Npub Pro as a front-end for reading, static HTML page for posting, no knowledge of Nostr whatsoever needed.

But I like the project, so that's not criticism, just explanation why I coded anonmicroblog like this.
