    Default examples and Ssl

    I want to learn how to use encryption using QSslsocket but it is to hard to me with out example. I know about Secure socket client but it is only client. I want to ask for write complet code changing: http://doc.qt.nokia.com/4.6/network-fortuneclient.html and http://doc.qt.nokia.com/4.6/network-fortuneserver.html

    Create a QTcpServer and use setSocketDescriptor to pass it a socket from QSslSocket.

    I do not understand where should I set:
    Qt Code:
    1. tcpServer->ignoreSslErrors();
    2. QFile *file = new QFile("server.key");
    3. QSslKey key(file, QSsl::Rsa, QSsl::Pem, QSsl::PrivateKey, "server" );
    4. tcpServer->setPrivateKey(key);
    5. tcpServer->setLocalCertificate("server.csr");
    To copy to clipboard, switch view to plain text mode 
    where should I set and what for it is:
    Qt Code:
    1. QSslSocket *serverSocket = new QSslSocket;
    2. if (serverSocket->setSocketDescriptor(socketDescriptor)) {
    3. connect(serverSocket, SIGNAL(encrypted()), this, SLOT(zmien()));
    4. serverSocket->startServerEncryption();
    5. } else {
    6. delete serverSocket;
    7. }
    To copy to clipboard, switch view to plain text mode 
    Could someone write complete code? It will be faster to learn for me.

    There are various complete examples out there, try the Qt-interest Archive for example, or doc.trolltech.com, both of which have SSL Server examples.

    You have right but example( http://doc.trolltech.com/solutions/4...r-example.html ) does not want compile because I have Qt 4.6.3, what should I do?

    Alter the code so it does want compile?

    If you don't understand the error messages, post them here. Perhaps someone can help.

    I modified http://doc.trolltech.com/solutions/4...r-example.html (see attachments)

    I am compaling typing: "qmake && make" and I see:
    Qt Code:
    1. sslserver.cpp: In constructor ‘SSLServerConnection::SSLServerConnection(quint16, QObject*)’:
    2. sslserver.cpp:22:33: error: ‘Server’ is not a member of ‘QSslSocket’
    3. sslserver.cpp:23:17: error: ‘class QSslSocket’ has no member named ‘socket’

    I would start with using method calls that actually exist. I have no idea where did you take that code from but it makes no sense - you are calling non-existing enums methods and even if they existed, they wouldn't work as you expect them to.

    It is not my code. I try compile example. I could not understand why compiler do not see "socket".

    What example? Please point me to an example that claims QSslSocket has a constructor like the one you are calling in your code.

    Maybe I do something wrong, I will start from original code. When I compile this: http://doc.trolltech.com/solutions/4...r-example.html I have:
    Qt Code:
    1. WARNING: /home/szarek/praca_inzynierska/temp/sslserver/sslserver.pro:5: Unable to find file for inclusion ../../src/qtsslsocket.pri
    2. sslserver.h:24:28: fatal error: qtcpserver.h: Nie ma takiego pliku ani katalogu(There is no such file or directory)
    3. compilation terminated.
    4. make: *** [main.o] BÅ‚Ä…d 1

    This example is not compatible with current Qt releases, it uses an outdated addition to Qt that since several months is incorporated into Qt. I suggest you turn to a "what I want to achieve" approach instead of "where do I find an example and how do I modify it to do what I want" one.
