Your conversations, your keys.
Direct messages and voice are end-to-end encrypted — the server stores zero plaintext and can't listen to your calls. Server channels are protected by transport encryption.
Hybrid Encryption Model
Voidcom uses a hybrid encryption model. Direct messages are end-to-end encrypted with post-quantum cryptography — the server never sees your DM content. Server channels use transport encryption so that server operators can moderate their communities.
- DMs encrypted end-to-end with XChaCha20-Poly1305 — the server stores zero plaintext
- Hybrid X25519 + ML-KEM-768 key exchange — quantum-safe, BSI TR-02102-1 compliant
- Voice E2E encrypted with per-channel keys — the server forwards packets it can't read
- Server channels protected by transport encryption
Key Management
DM encryption keys are generated locally and never leave your device. Hybrid post-quantum key exchange protects against harvest-now-decrypt-later attacks. Per-channel voice keys support rotation.
- DM encryption keys stored on your device only
- Per-channel encryption keys with rotation support
- Post-quantum key exchange protects against future quantum threats
