    Hemmelig is a privacy-focused secret sharing service that lets users securely share sensitive information like passwords, API keys, private notes, or confidential links using client-side encryption so that the server never sees unencrypted data.

Users can generate shareable links with optional expiration times, view limits, and password protection to tailor how and when secrets are consumed, and links automatically expire or self-destruct after use to prevent reuse or exposure. ...
