How to get CPU serial number using HISE?

[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?

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

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

Is this fix already implemented?

@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.

@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.

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..)

@ustk Got it sorted. Sending to beta for testing now.

@Dan-Korneff Hey buddy, sorry to bother you, I don't know what's going on with GitLab, I can't see your code on GitLab, will you publish it on GitHub? Or is there another way for me to get it? I will be very grateful

[Dan Korneff]

@CatABC I set the repo back to private.
Here's a link to the files:
https://hub.korneffaudio.com/index.php/s/M6kgXeaZ9BstR7Q
This will replace the existing method with the new one. No need to keep the old one since it's flawed.

[CatABC]

@Dan-Korneff Thank you so much! I don't know how to thank you, you are my big brother, hahahaha

[CatABC]

@Dan-Korneff I used your file, but the generated machine code is the same as the original one. I'm not sure if this is normal. Could you give me an answer?

[Dan Korneff]

@CatABC You have to enable this setting in projucer and rebuild HISE:

Now HISE will use the new code to gather system IDs.

Then you need to set JUCE_USE_BETTER_MACHINE_IDS=1 in your project so the exported plugin references the correct system ID.

[CatABC]

@Dan-Korneff well，I understand！thanks bro！
