Cloudfare doesn't let me through. 🙄

How does the anonymity work?

OnionShare already has a chat feature that works pretty well. What does this add?

Thanks for sharing I recommend Cheogram web which is in beta but will reach the full feature set of the app in due time

A few ideas that could further strengthen the design:

• Consider deriving separate keys from a master secret using HKDF (e.g. encryption key, authentication key, attachment key) instead of relying on a single key for everything.
• Room IDs alone could leak metadata if discovered. An HMAC-based room authentication scheme could help without requiring the server to know any encryption keys.
• Adding replay protection with counters/nonces and periodic key rotation would make the protocol more resilient.
• For public deployments, some abuse protection (rate limiting, room creation limits, optional proof-of-work) would help prevent DoS attacks.
