QMaskGenerator¶
The
QMaskGenerator
class provides an abstract base for custom 32-bit mask generators. More…
Detailed Description¶
The specification as outlined in RFC 6455 requires that all communication from client to server be masked. This is to prevent malicious scripts from attacking badly behaving proxies. For more information about the importance of good masking, see “Talking to Yourself for Fun and Profit” by Lin-Shung Huang et al . By default
QWebSocket
uses the reasonably secureglobal()
->generate() function. The best measure against attacks mentioned in the document above, is to useQWebSocket
over a secure connection (wss:// ). In general, always be careful to not have 3rd party script access to aQWebSocket
in your application.
