Every time Hyper-V is enable/disable cause the hwid changes (Ethernet)

Every time enable/disable Hyper-V, will cause hwid changes. (generat new Ethernets).

It means your customer able to trial permanent your hardware-lock trial version.

Additional information: My system installed VMWare and Hyper-V, so you can see multiple ethernets.

Re: Hardware identifier feature - useless

Maybe same problem to me.
If you enable/disable Hyper-V and restart, the hwid will change.

Re: Can not create serial number: Serial number is too long

I think I've figured out that a 2048-bit key can only encrypt up to 256 bytes of data.

After subtracting 11 bytes of nMinPadding, the remaining 245 bytes are available.

As image, I can't add a Custom Name that it's length 255 to the license.

Does HWID have a maximum length?

In some scenarios, I need to know its size in advance to set up storage buffers, such as database fields.

Re: Has anyone tried to use the Activation API in the driver(.sys) ?

1. Driver generate the "text block" then return to user-mode app via DeviceIoControl. 2. User-mode app sends the "text block" to WebLM offline activation. (I never try WebLM offline activation now, does it return a serial number to user for next step ?) Just use activation APIs ...

Re: Has anyone tried to use the Activation API in the driver(.sys) ?

Explain further why I insist on checking the serial number in the driver, since I don't know much about the field of software security, if there are any mistakes, please correct them. 1. Because user-mode applications can run without digital signatures, it can be modified and still run. So I think e...

Re: Has anyone tried to use the Activation API in the driver(.sys) ?

You can make an user-mode activator for your driver. I don't see any problem in this. Does the Offline Activate APIs works in driver ? My idea: 1. Driver generate the "text block" then return to user-mode app via DeviceIoControl. 2. User-mode app sends the "text block" to WebLM ...

What the "VMProtectDDK32(64).sys" works for ?

In the VMProtect installation directory "..\VMProtect Ultimate\Lib\Windows", I can see a file named "VMProtectDDK32(64).sys".

I know the "VMProtectDDK32(64).lib" is works for building driver, but what does the "VMProtectDDK32(64).sys" do ?

God, I bought both VMProtect Ultimate and WebLM, can I refund the WebLM ?

I read the description in the user manual, and it seems that it only supports http, not https. Is it safe?
