How to get CPU serial number using HISE?

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.

@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.

@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

@Christoph-Hart Here's where I'm at:

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

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

Dan Korneff

@Christoph-Hart @ustk Confirmed working:

https://gitlab.korneff.co/dankorneff/HISE/-/commit/70837baec92f3dda87ca88f34c694017978a5c57

It requires 2 new files:
juce_Span.h
juce_EnumHelpers.h

and edits to:
juce_core.h
juce_win32_SystemStats.cpp
juce_SystemStats.cpp
juce_OnlineUnlockStatus.cpp

@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.

Felix W

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

Felix W

@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.

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

@Dan-Korneff Hello Dan, after compiling your C++ code, I found a problem. When a new display device is connected, the machine code will change. I wonder if you have this problem?

I haven't seen this yet.

It seems this issue is still here.

I have a situation where a customer apparently needs to re-activate the license each time he wants to use the plugins.

I have very sparse information, but this is probably due to a changing MachineID after a restart. I have told the customer to verify if the current ID matches the one in the currently activated license to confirm the theory. Hopefully I'll get this crucial information.

In the waiting, is there anything I could do aside of just using JUCE_USE_BETTER_MACHINE_IDS?
