Can QSslSocket be used immediately after startServerEncryption()?

Question

After I've called QSslSocket::startServerEncryption() , can I proceed to immediately use the socket as an ordinary QTcpSocket, reading and writing data from it, or do I need to call waitForStartEncrypted() before using it?

socket->startServerEncryption();
socket->waitForEncrypted(); // <==== Is this line necessary?
socket->write(data);
QByteArray response = socket->read();

You can start to use it immediately. The data will be buffered and sent later. Note that you can't read any data from it yet, since none will have arrived. The actual connection and handshake will not occur until you enter the event loop.
