Is there a nostr app, which would work as a pendent to GNU privacy guard for signing documents? Where I could input any kind of document before sending it to someone and then it would be signed with my npub?

Maby this could be a thing to share documents in a reliable way, to make sure whoever reads it can verify its autenticity more easily?

Could be even useful for corporate documents, to sign documents digitally to confirm the authenticity of a document. Or can this even be accomplished with current implementations of GPG and just feeding them the nsec together with the correct algorithm?
