Java-WebSocket is a collection of classes for implementing WebSocket clients and servers using pure Java. It provides a framework for hosting servers that manage connections via event-driven subclasses and tools for establishing client connections to remote servers.
The library includes a secure communication tool for encrypting traffic using the WSS protocol and a compression library that uses per-message deflate extensions to reduce transmitted data size. It supports the configuration of cipher suites to limit encryption protocols and ensure compatible communication.
The project enables bidirectional, non-blocking data exchange between clients and servers. Its capabilities cover secure network communication and bandwidth optimization to facilitate real-time data exchange.
