Encrypted real-time chat: how it works
Premium Chat is designed for temporary conversations where messages and files leave the browser already encrypted. It combines a real-time path with encrypted-history recovery when a direct connection is not enough.
Updated September 13, 2026
Encryption at the source
Chat content is encrypted in the browser before it is sent. The room password is transformed locally into key material; the server operates on ciphertext and the technical metadata required to keep the room working.
This reduces exposure of message content on the server, but it does not eliminate every operational metadata item.
Real time and reconnection
When possible, the chat uses WebRTC for fast participant-to-participant delivery. At the same time, persistent history is stored as ciphertext so a participant can recover events after a disconnection. Decryption takes place on the client.
Expiration, participants and destruction
A room has an expiration time and participant limit selected at creation. The creator can destroy the room before expiration. Server-side destruction removes encrypted history and room files; an offline device can only clear its local data when the application runs again.
Practical checklist
- Create a strong, unique room password.
- Send the room link and password separately when possible.
- Choose the shortest practical room lifetime.
- Confirm who is participating.
- Destroy the room when the conversation is complete.
Common questions
Does the server store chat history?
To support reconnection, the server can store persistent history as ciphertext together with minimal operational metadata.
Does Chat use only WebRTC?
No. WebRTC is the fast path when available, while HTTPS is also used for signaling, encrypted persistence and recovery.
