How to get CPU serial number using HISE?

[Oli Ullmann]

@ustk
Do I have to use this when I compile HISE, or do I use it when I compile the plug-in?

Thank you
Oli

[ustk]

@Oli-Ullmann Both, otherwise the ID created will not be the same during test and production.
Once you use this flag it's forever for compatibility reasons
It should be set to true by default imho, but I think it's for breaking old project compatibility that it's false... @Christoph-Hart ?

[Oli Ullmann]

@ustk
All right, that makes sense. Thanks for the info! :-)

I'm not sure what I'm doing wrong here, but HISE and my compiled plugin can't agree on a "better" machine ID.

I've compiled HISE like this:

and added this to my project:

When I launch the plugin, it detects that the ID is different and I update my license file. Then when I load HISE, it still thinks that the ID is different. What am I doing wrong?

[ustk]

@Dan-Korneff Have you tried to set it in the 'Modules` tab instead? That's what I do because I always think some pre-processor aren't working, that might be the case for this one...

[Dan Korneff]

@ustk I've changed the preprocessor in the module like this:

Still the same result

[Dan Korneff]

It appears to be something with the exported plugin. The machine IDs generated with JUCE_USE_BETTER_MACHINE_IDS=1 are the same as if it's set to false. At least I know where to start looking

[Dan Korneff]

Ok... I've obviously have not had enough coffee today. I'd probably have to export the plugin after I rebuild HISE for something to take effect.
Ignore my stupidity for now.

[ustk]

@Dan-Korneff yeah it can be troublesome to be sure both are working (hise and plugin)

[Dan Korneff]

I'm using JUCE_USE_BETTER_MACHINE_IDS=1 in my new project. It's mostly working well, but I have a couple Windows 11 users that have to reactivate their license every few reboots. Is there a way to list the devices that are used to create this number so I can debug what is changing on their system?

[ustk]

@Dan-Korneff Ouch! As it doesn't respect what the name says, that is very unfortunate!

[Dan Korneff]

@Christoph-Hart I think this is the issue:
https://github.com/juce-framework/JUCE/commit/120f9266dc881c81371109c69b37a0a246accdeb

Is this fix already implemented?

[Christoph Hart]

@Dan-Korneff welp it‘s time for a JUCE_EVEN_BETTER_MACHINE_IDS macro…

You can fetch the MachineGuid that Windows creates on install using powershell. Here's how you do it in HISE:

const BackgroundTask = {};

BackgroundTask.getMachineGuid = Engine.createBackgroundTask("GetMachineGUID");
inline function getMachineGuid()
{
	local command = "reg";
	local args = 
	[
	    "query",
	    "HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Cryptography",
	    "/v", 
	    "MachineGuid"
	];
	
	local logFunction = function(thread, isFinished, data)
	{
		if (!isFinished)
		{
			var id = data.substring(data.indexOf("REG_SZ")+6, data.length).trim();
			
			Console.print(id);
		}

	};

	
	BackgroundTask.getMachineGuid.runProcess(command, args, logFunction);
}

getMachineGuid();

A bit silly function naming since it won't return anything, but you get the gist.

[Dan Korneff]

@aaronventure I've created an app that displays the system ID with the Engine.getSystemID() function. I was looking for something that displayed the items in the system that were used to create the numbers.
Ultimately, it looks like there's a fix available from JUCE. Looking forward to the update

[Dan Korneff]

@Christoph-Hart No rush. Just checking in for a friendly ETA.

[Dan Korneff]

@Christoph-Hart Would you want to give me a "this is how I would do it" outline and I could take a run at it? Just trying to manage the pitchforks.

[ustk]

@Christoph-Hart said in How to get CPU serial number using HISE?:

@Dan-Korneff welp it‘s time for a JUCE_EVEN_BETTER_MACHINE_IDS macro…

Where are we at about this GENERATE_FOOL_PROOF_ID?

[Dan Korneff]

@ustk I think the method can just be swapped out with the new one.
I've been tinkering with implementation on this end. Lots of little hurdles backporting from juce 8. Got a huge stack trace to work out, but I've been too swamped to complete

Any chance you could take a look? (ignore the image file stuff..)
