Qwing

Qwing is a private messenger built for the post-quantum era.

Every message, call and file is protected with end-to-end encryption based on NIST-standardized post-quantum cryptography (ML-KEM-1024 and ML-DSA-87 with XChaCha20-Poly1305) - designed so that even tomorrow's quantum computers can't read today's conversations.

FEATURES

PRIVACY BY DESIGN

- Servers never see message content - only encrypted envelopes

- Media travels peer-to-peer whenever possible
