Trick is a cross-platform offline messaging application that provides end-to-end encrypted communication without server infrastructure. It uses Wi-Fi Aware (Neighbor Awareness Networking) for direct peer-to-peer discovery and communication, and the Signal Protocol with Kyber-1024 post-quantum cryptography for message confidentiality. The application targets scenarios where internet access is unavailable, such as disaster response and remote deployments.
