Q-Audion

Q-Audion is an end-to-end encrypted communication app for voice calls, video calls, and text messaging. Every conversation is protected by a hybrid handshake combining classical cryptography (X25519) and post-quantum cryptography (ML-KEM), so your communications stay secure even against future quantum computers. Content is encrypted with AES-256-GCM and XChaCha20-Poly1305: only you and your contact can read it, never the server. Key features: — End-to-end encrypted voice and video calls — Text messaging with encrypted delivery — Hybrid post-quantum key exchange (ML-KEM + X25519) — Contact identity verification via security fingerprint — Encrypted file attachments and voice notes — Block and report contacts directly in the app — Optional Bluetooth mesh: with no network, messages that are already encrypted can pass between nearby Q-Audion phones, only with your consent Q-Audion is built…
