Hemmelig
Open source, encrypted secret sharing service with self-destruct and password protection.
About Hemmelig
Hemmelig is an open source tool for sharing secrets like API keys, passwords, and private URLs in a way that leaves no trace. It encrypts everything in the browser before any data reaches the server, so the host never sees your plaintext. You set a time-to-live or a maximum number of views, after which the secret is permanently deleted.
You can optionally protect a secret with a password and require a recipient to decrypt it on their end. Hemmelig runs as a web app but also ships as a self-hosted Docker container, so teams can keep everything inside their own infrastructure. The project is built with Node.js and uses AES-256-CBC encryption, all open source on GitHub.
It is especially useful for developers and SREs who need to hand over credentials in chat or ticketing systems without leaving a permanent record. The hosted version is free for basic use, and self-hosting is free under the MIT license. Hemmelig has no telemetry by default and no user accounts required.
