An e2e secret sharing website with client-side encryption
Sub Rosa is a zero-knowledge secret sharer. We physically cannot read your messages. Most tools generate keys on the server. We don't. Your browser encrypts data locally using the Web Crypto API. The key lives in the URL hash (#) and never touches our logs or database. We only store the encrypted blob, which is burned instantly after reading. 100% Open Source. No ads. No trackers. Just privacy.
