Technology
AURA is a private messenger for chats, groups, channels and posts. Its architecture starts on the device: OPAQUE protects account access, the protected protocol encrypts every message, and AURA Core adds mode-specific safety without sending conversations to the cloud.
End-to-end message encryption
Hybrid post-quantum E2EE protocol. Wraps every message in a fresh key derived from the symmetric ratchet - neither AURA nor any intermediary can decrypt. Audit-ready Rust shipping in beta today.

Zero-knowledge sign-in (OPAQUE)
OPAQUE aPAKE protocol. Your password is never transmitted, never stored. Mutual authentication and forward secrecy, hardened with a post-quantum KEM layer using an AND-model combiner.

On-device contextual safety runtime
A messenger-native safety engine for Kids and Military modes. It combines patterns, local ML and conversation context to select proportional policy actions before harm escalates. In active development; specifications below describe the v1 scope.
