Loading an SSL certificate located in code



  • Hey,

    I want to make load a QsslCertificate which I have copied from the .pem file into the code. It looks like this:

          const char * certData = "-----BEGIN CERTIFICATE-----\
     dY32TQ==\
    (...)\
     -----END CERTIFICATE-----";
        QSslCertificate cert(certData);
        if (cert.isNull()) {
            QMessageBox::information(0,"Certificate is null.", certData);
        }
    

    But cert.isNull() returns true. How do I need to reformat my certificate data for it to load correctly?

    Thanks!
    Nathan



  • Well, I managed to load my certificate using

    QList<QSslCertificate>  certs = QSslCertificate::fromPath(":/certificate.pem");
    

    And adding certificate.pem to the resources.



  • Please this code from me where I did exactly this:
    https://github.com/cybercatalyst/qtwebserver/blob/master/tcp/tcpmultithreadedserver.cpp#L141

    void MultithreadedServer::setDefaultSslConfiguration() {
    // Set a default SSL configuration just to have it running out of the
    // box. Only for development purposes, never distribute an application
    // that relies on SSL with the default configuration set. You can
    // generate your own key and self-signed certificate:
    //
    // $ openssl req -x509 -newkey rsa:2048 -keyout server.key -nodes -days 365 -out server.crt
    
    QSslConfiguration sslConfiguration;
