You can use a local event loop to wait for the signal to be emitted :

QTimer timer;
timer.setSingleShot(true);
QEventLoop loop;
connect( sslSocket, &QSslSocket::encrypted, &loop, &QEventLoop::quit );
connect( &timer, &QTimer::timeout, &loop, &QEventLoop::quit );
timer.start(msTimeout);
loop.exec();

if(timer.isActive())
    qDebug("encrypted");
else
    qDebug("timeout");

Here it waits until encrypted is emitted or the the timeout reaches.
