Hardware IDs (HWIDs) are unique identifiers that can be used to authenticate devices or applications. They are often required for licensing or security purposes. In this article, we will show you how to generate HWIDs with Qt, a cross-platform framework for creating graphical user interfaces and applications.
Qt provides a class called QSysInfo that can access various system information, such as the operating system name, version, architecture, and build. It also has a static function called machineUniqueId() that returns a QByteArray containing a HWID for the current machine. The HWID is based on the MAC address of the primary network interface and the serial number of the CPU or motherboard. The function uses a cryptographic hash algorithm to ensure that the HWID is not reversible or guessable.
To use the QSysInfo class, you need to include the header file <QSysInfo> in your source code. You can then call the machineUniqueId() function and convert the returned QByteArray to a hexadecimal string using the toHex() function. For example:
The output of this program will look something like this:
You can then use this HWID for your own purposes, such as verifying licenses or encrypting data. Note that the HWID may change if you change the hardware components of your machine or reinstall the operating system. Therefore, you should always store the HWID in a secure location and update it when necessary.

If you want to create an epub file from your Qt HWID Generator program, you can use a library called qt-epub that is available on GitHub[^5^]. This library is a qt based epub reader that can also write epub files. It uses libarchive and QZip to handle zip compression and decompression, and QTextBrowser to display the epub content.
To use the qt-epub library, you need to clone or download the repository from GitHub and include the header files <QEPub> and <QZip> in your source code. You can then create an instance of the QEPub class and use its methods to write your epub file. For example:
QString html = \"<h1>Introduction</h1>\\n\"
\"<p>This is a Qt program that can generate hardware IDs (HWIDs) for your devices or applications.</p>\\n\"
\"<p>A HWID is a unique identifier that can be used to authenticate or license your software.</p>\\n\"
\"<p>To generate a HWID, you need to use the <code>QSysInfo</code> class and its <code>machineUniqueId()</code> function.</p>\\n\";
// Close the epub file
This program will create an epub file called \"Qt HWID Generator.epub\" that contains a cover image, a stylesheet, and a chapter with some html content. You can then open the epub file with any compatible reader or device.
