        Hi everybody,

        inspired by @Lindon's remarkable efforts to wrap a copy protection system....

        remarkable only in the level of doofus inability to work things out by me really....

          "we use the Engine.dumpAsJSON() method to just store their entered serial to a file which is loaded every time the plugin is instanciated."

          The only additional thing I usually do is obfuscate this "number" - put it at random spots in a inside a 60 digit sequence - 9's complement - that sort of stuff... but that might be a little paranoid on my part.

            What purpose does that serve?

              @d-healey it makes me feel good....☺

              Actually I dont store all the numbers in the interface - I use an formula to calc if the entered numbers are valid or not...Kontakt is so much easier to hack the (KSP) code so including the numbers was never really an option. HISE not so much of a problem. One more win for HISE...

                @Lindon Any good hacker can hack everything. If you don't use advanced challenge system (that requires taking machine ID and checks / registers online status...etc) they can hack everything including live serial generation formula system... So, this Serial protection with formula system has the same risks with "Simple Copy Protection" solution...

                      This is not designed to be a super secure copy restriction system, it is designed as a sharing deterrent for regular none techy users.

                          Yes, if you come up with a way to validate serials without storing strings in the binary, you solve a few issues of this approach:

                          • if you run out of serials, you have to reencode the plugin (or choose a big enough serial amount in the first place)
                          • smaller footprint and compile time (creating more than a few thousand strings will defer the plugin start for your user)

                          There aren't too much security features in HISEScript, but you can use one of these tricks:

                          • create the sum (poor man's hash) of the string character values and make sure it matches a rule you define.
                          • disallow certain characters
                          • any kind of cheap encryption algorithm should be enough.

                          This function can be used to create a "hash" from a string:

                          const var s = "ABCD";
                          
                          var x = 0;
                          
                          inline function createHash(text)
                          {
                              local sum = 0;
                              
                              for(i = 0; i < text.length; i++)
                              {
                                  sum += text.charCodeAt(i);
                              }
                              
                              return sum;
                          }
                          
                          x = createHash(s);

                              Use the latest (updated today) HISE version.
                              Use Authorisation.js code with Content.makeFrontInterface like below. Also don't forget to include("Serials.js") to make the function check. All of the UI elements will be activated. I tried and compiled a plugin, it works likea charm. It creates "RegistrationInfo.js" in User presets main folder. Interface code example is this;

                              Content.makeFrontInterface(600, 500);
                              
                              
                              include("Serials.js");
                              
                              
                              
                              namespace Authorisation
                              {
                                  const var SerialInput = Content.getComponent("SerialInput");
                                  const var Description = Content.getComponent("Description");
                                  const var SerialStateLabel = Content.getComponent("SerialStateLabel");
                                  const var AuthorisationDialogue = Content.getComponent("AuthorisationDialogue");
                                  const var GlobalMute = Synth.getMidiProcessor("GlobalMute");
                                  
                                  /** Checks if the serial input is valid and stores the result if successful. */
                                  inline function onSubmitButtonControl(component, value)

                                      local v = SerialInput.getValue();
                                      Console.print(v);
                              	
                                      // Checks if it's in the input

                                Yes you need today's HISE version, I changed the behaviour of the Engine.loadJSON() method to return undefined instead of throwing an error (which will be the default case if the file wasn't written yet).

                                  ok

                                  actually compiling the latest hise standalone project.

                                  if i understand well i also could add the SerialGenerator.js script to the interface to generate a brand new serial list instead of the given one ?

                                  all the component are labels (save in preset no, and just the input serial editable) ? except the Submibutton of course ;)

                                  EDIT:
                                  Just added this line:
                                  Description.set("text", "Valid serial number. The number you supplied does match");
                                  in :
                                  if(serials.Data.contains(v))
                                  {
                                  Console.print("Serial number found");
                                  Description.set("text", "Valid serial number. The number you supplied does match");

                                  Because without that it always shows that it's invalid in the Description Label. :D

                                  Excuse me i'm French.

                                          @Christoph-Hart OK quick supplemental question - has "today's HISE" fixed the problem of dialogs not showing fully in interfaces less than 500 px high or do I have to go modify my UI design a bit?
