examples and Ssl

[szarek]

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

Have you tried reading the documentation?

Thank you for your respond. It is perfect example for client but where is code for server?

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

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

I do not understand where should I set:

tcpServer->ignoreSslErrors();
    QFile *file = new QFile("server.key");
    QSslKey key(file, QSsl::Rsa, QSsl::Pem, QSsl::PrivateKey, "server" );
    tcpServer->setPrivateKey(key);
    tcpServer->setLocalCertificate("server.csr");

tcpServer->ignoreSslErrors();
    QFile *file = new QFile("server.key");
    QSslKey key(file, QSsl::Rsa, QSsl::Pem, QSsl::PrivateKey, "server" );
    tcpServer->setPrivateKey(key);
    tcpServer->setLocalCertificate("server.csr");

To copy to clipboard, switch view to plain text mode 

where should I set and what for it is:

QSslSocket *serverSocket = new QSslSocket;
    if (serverSocket->setSocketDescriptor(socketDescriptor)) {
        connect(serverSocket, SIGNAL(encrypted()), this, SLOT(zmien()));
        serverSocket->startServerEncryption();
    } else {
        delete serverSocket;
    }

QSslSocket *serverSocket = new QSslSocket;
    if (serverSocket->setSocketDescriptor(socketDescriptor)) {
        connect(serverSocket, SIGNAL(encrypted()), this, SLOT(zmien()));
        serverSocket->startServerEncryption();
    } else {
        delete serverSocket;
    }

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?

[squidge]

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:

What have to I correct?

[wysota]

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.

[szarek]

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

[wysota]

I try compile example.

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

[szarek]

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:

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.
