The Hardware ID Extractor is a library for programmers. It offers functions that extract data about your computer's hardware (CPU, HDD, RAM, main board, video BIOS), including unique hardware identification numbers. The data is extracted via low level functions DIRECTLY from computer's hardware. This means that the data cannot be faked! The DLL is ideal for creating highly reliable protections schemes for your application. Source code, compiled DLL and demo application are available.
Programming languages supported The DLL provided was compiled using the standard calling convention (StdCall). Therefore, it is compatible with all modern programming languages such as C Builder, Visual C (basically all strains of C/C++), Visual Basic, Liberty Basic, Visual Fox Pro, Delphi, Lazarus, Free Pascal, PowerBuilder, Clarion, Visual Studio (C#, VB). The DLL also supports Microsoft VBA powered languages such as Word, PowerPoint 2000, 2003, 2007, Excel, Access or other scripted languages. Click here to see how to call the DLL from your language.

The functions offered by this library can read the following hardware information:
Hard disk
CPU
Physical memory
BIOS (NEW!)
Detailed list off exported functions is available here.
You can download the DLL right now. It is FULLY functional and requires no installation. Some of the functions exported are free, others will display an ad. Get a key to unlock all functions (to stop it from displaying the ad).
Delivering the DLL with your applications
You can deliver our DLL along with your product. You don't need to install the DLL in Windows folder. Just leave it in your application's folder. If you want you can rename the DLL to anything you want - it will still work. The DLL is very small and doesn't need to be registered with RegSvr32.
The DLL/source code is royalty free. Once you purchase it you can distribute it with your own applications.
This library can be used to:
Why any programmer MUST use hardware-signed keys?
Using hardware-signed keys you will increase your profit. There is a chain of three events that leads to increased revenue:
There are several good reasons to choose our library:
HDD For example when they read the HDD they get the volume ID. This number is indeed unique but it changes every time the user formats the drive to reinstall its operating system. We also offer a function to read this number. However, we offer the real deal: a function that reads the device ID written by manufacturer in hard drive's IDE chip. This number is absolutely unique on the planet (no other hard drive has this ID) and it is 100% unchangeable.
CPU The same for CPU. They offer a function to read the unique serial number of the CPU. While this worked perfectly with single core CPUs, none of the libraries we have tested works properly with multi core CPUs. This is because the application can have access only to the core in which it currently runs. Unfortunately, Windows can start the application in any core, therefore you will probably see four different ID's for a quad-core CPU. Our library is the only one that works properly and extracts the correct CPU ID number. Note:
NIC Other libraries offer you a function to read the MAC of the network card. We just decided not to bother offering such a functions since the MAC can be so easily changed.
PRICE There is also the "small" issue called PRICE. Similar libraries force you to pay the big buck to purchase them. Usually the prices are around $100 for DLL and many hundredths of dollars for source code.
FLEXIBILITY Other DLLs does not allow you low level access to the functions that extract the hardware identification numbers (maybe they try to hide that their library don't extract the true serial numbers). Instead the offer you access to a single function that extracts some the numbers hashes (MD5) these numbers and finally returns to you the hash. Our DLL gives you access to all its inner working! You can decide which hardware to read and which not and to implement the protection system exactly the way you want/need!
Overall, most concurrent products around do not offer you the true hardware ID, are really expensive, don't show you what happens under the hood, don't provide the code, are unreliable or difficult to use.
Here you can download the DLL, the source code and a compiled demo application called Hardware ID Extractor that reads the hardware information and displays it on screen. This demonstration application is 100% freeware. See screenshot.
DOCUMENTATION
The source code
The Hardware ID Extractor source code can be purchased separately. The source code contains assembler code and very few Windows API calls. The source code was tested under Delphi 7, Delphi 2006 and Delphi 2007. We offer the code as it is. We cannot offer support for other programming languages/versions, but since you have the source code you can easily adapt it for your needs. Of course, if you purchase the source code you won't have to distribute any DLL with your application anymore.
Functions exported by the DLL & additional info
The Hardware ID Extractor library was written in Delphi. However, it is available to all programers via our DLL. All functions in the DLL are exported a stdcall so the DLL is fully compatible with C, C++, Visual Basic (all editions), Dot Net languages (C# etc), Java, FoxPro, Liberty Basic, etc Most of these functions are also available via our DLL; other functions are used internally and are not exported by the DLL.
How to call the DLL from your programming language
In this page you will find examples of how to call the DLL and to use the functions exported from your preferred programming language (C, VB, C#, FoxPro, VBA, Basic, Java, etc). After you load the DLL you can access the hardware information as easy as calling a single function.
