Description

The QSslSocket class provides an SSL encrypted socket for both clients and servers.QSslSocket establishes a secure, encrypted TCP connection you can use for transmitting encrypted data. It can operate in both client and server mode, and it supports modern SSL protocols.

SSL encryption operates on top of the existing TCP stream after the socket enters the ConnectedState. There are two simple ways to establish a secure connection using QSslSocket: With an immediate SSL handshake, or with a delayed SSL handshake occurring after the connection has been established in unencrypted mode. The most common way to use QSslSocket is to construct an object and start a secure connection by calling connectToHostEncrypted(). This method starts an immediate SSL handshake once the connection has been established.

#include <QApplication>
#include <QSslSocket>
#include <QDebug>
 
int main( int argc, char **argv )
{
QApplication app( argc, argv );
 
QSslSocket socket;
socket.connectToHostEncrypted( "bugs.kde.org", 443 );
 
if ( !socket.waitForEncrypted() ) {
qDebug() << socket.errorString();
return 1;
}
 
socket.write( "GET / HTTP/1.1\r\n" \
"Host: bugs.kde.org\r\n" \
"Connection: Close\r\n\r\n" );
while ( socket.waitForReadyRead() ) {
qDebug() << socket.readAll().data();
};
 
qDebug() << "Done";
 
return 0;
}
