Hemmelig

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. It operates with a zero-knowledge architecture: all encryption and decryption happen in the browser, and only encrypted blobs are transmitted to and stored on the server, reducing the risk of leaks or unauthorized access. 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. The platform supports easy deployment via Docker or hosted options, making it practical for individuals, teams, or enterprises that want to safeguard secrets without relying on third-party storage.
