Introduction

QtWebSockets is a pure Qt implementation of WebSockets - both client and server. It is implemented as a Qt add-on module, that can easily be embedded into existing Qt projects. It has no other dependencies than Qt.

Features

• Client and server capable
• Text and binary sockets
• Frame-based and message-based signals
• Strict Unicode checking
• WSS and proxy support

Update Notice

In this update, we have added a pre-shared encryption handshake feature to QWebSocketServer, enhancing the security of communication between the server and clients.

New Feature

• Pre-Shared Encryption Handshake
  • Files: QWebSocketServer.h and QWebSocketServer.cpp
  • Added the preSharedEncryptionHandshake function to handle encryption handshakes using pre-shared keys.

void preStartedEncryptionHandshake(QSslSocket *pTcpSocket);

This modification is based on the Qt source code. For more information, please visit the Qt website.
