E2EE Protocol
End-to-End Encryption protocol for WebSocket messaging. Messages are encrypted on the sender and can only be decrypted by the intended recipient — the server never sees plaintext.
End-to-End Encryption protocol for WebSocket messaging. Messages are encrypted on the sender and can only be decrypted by the intended recipient — the server never sees plaintext.
End-to-end-encrypted direct + group messaging subprotocol. The server only sees ciphertext — keys are exchanged client-to-client.
