Overview
A pure Dart implementation of the Signal Protocol, enabling secure, end-to-end encrypted communication in Flutter and Dart applications. Designed for cross-platform use, it supports Android, iOS, Web, macOS, Windows, and Linux. The library provides robust cryptographic primitives essential for private messaging, including key exchange, message encryption, and session management. Built by Mixin Network, it ensures compatibility with existing Signal Protocol ecosystems while maintaining performance and security standards across platforms.
