Profile

This project has been kicking around in my head since I first heard about the webauthn PRF extension in early 2024. I've slowly chipped away at it since, and finally got things to a shareable state over the summer thanks to a very fun parental leave. Headed back to work tomorrow, so I figure there's no time like the present.tldr: A client-held encryption key derived during passkey authentication encrypts all sensitive user data prior to persistence so that only the user is able to decrypt and reuse that data on their device. This allows short-lived, privacy-preserving age proofs to be issued to requesting applications (18+, no PII shared) without requiring users to re-upload their documents.

The company sits in the show hn launch segment, where it competes on its core product or service.

Directory data places it at the Show HN launch stage.
