CUEBES uses end-to-end encryption (E2EE) to protect your private messages, ensuring that only you and the recipient can read them.
How It Works
CUEBES implements a Signal Protocol-inspired encryption system:
- Key exchange — X25519 (Curve25519) for key agreement
- Message encryption — XChaCha20-Poly1305 for authenticated encryption
- Per-message keys — Each message uses a unique encryption key
What This Means for You
- CUEBES cannot read your encrypted messages, even if compelled by law
- Messages are encrypted on your device before being sent
- Only your registered devices can decrypt your messages
Managing Your Devices
Manage your E2EE devices from Settings > Encryption.
Important: If you lose access to all your devices and backup codes, you will not be able to recover encrypted messages.
