      Compile OpenSSL and link it to your project, separately for each platform.

      On Android you can use KDAB's scripts: https://github.com/KDAB/android_openssl

      There is also some documentation about it https://doc.qt.io/qt-5/android-openssl-support.html

        @sierdzio , thank you, is this likely to be an option in the software somewhere as I don't see any openSSL references in the source, could it just be a Qt setting somewhere?

        Kind Regards,
        Sy

          On the node of OpenSSL I would like to mention, that the QtOnlineInstaller now comes with the option to download the correct/needed openssl dll's no need to search for/compile the correct versions yourself anymore 🎉

            @J-Hilk , its very odd, I have two projects, one is a newer version of the original project and that does not come up with these messages. The project I'm working on is the original version and my task is to port it to Qt 5.8.

            I've compared the .pro files and the libraries included are the same, I've also single stepped the source, these messages do not appear until the QML is opened.

            Kind Regards,
            Sy

              @SPlatten well QML allows for network access (its well integrated)

              This for example:

              Window {
                  id: window
              
                  width: 800
                  height: 600
              
                  visible: true
              
                  Image {
                      anchors.fill: parent
                      source: "https://www.extremetech.com/wp-content/uploads/2020/01/NASA-Sun.jpg"
                      fillMode: Image.PreserveAspectFit
                  }
              }
              

              works fine and should require openssl support

                @J-Hilk , there are no http references in the project, images are all from the resource file.

                  @SPlatten said in qt.network.ssl: QSslSocket cannot resolve...:

                  SSL_set_psk_client_callback

                  The missing symbols were added in OpenSSL 1.1.1. Most likely you are still linking OpenSSL 1.1.0 or something.

                      Just the regular linking:

                      INCLUDEPATH+=/path/to/openssl
                      LIBS+=/path/to/openssl
                      

                      I don't see any openSSL references in the source

                      Then, as I mention, you can just ignore these messages. Or disable them using categorizable logging config.

                        @sierdzio can this actually disable runtime messages?

                              @SPlatten if you are on Windows then simply copying libcrypto-1_1.dll and libssl-1_1.dll from the OpenSSL binaries (install them via the Qt Installer) to the path that contains your .exe should fix this as well (without needing to explicitly link at compile time).
