What is 0 am and ULDA?

0 am’s ULDA (Universal Linear Data Authentication) is a lightweight JavaScript/TypeScript library that adds strong client-side encryption to your project in just three lines of code. All data are encrypted and signed in the browser with the Web Crypto API, then streamed over a secure WebSocket channel (socket.io-client) for fast real-time sync. ULDA runs 100 % on the front-end—no server-side changes required.

Rather than serving as a full data-management framework, ULDA gives you a straightforward model of “master” and “content” JSON files—a minimal, easy-to-grasp scaffold that lets you encrypt, sign, and keep multiple clients in sync without deep cryptography knowledge. If your app needs rock-solid confidentiality, integrity, and live updates with zero backend refactor, ULDA is the drop-in toolkit.
