HWID Info Grabber

Introduction

This project is an example of how computer components have hardware identifiers that can be used by developers to lock applications to specific computers.
This code is from a video where I explain how to control distribution of applications and prevent piracy.

Code Samples

Retrieving HDD information, the HDD serial is most commonly used for locking applications.

	TCHAR volumeName[MAX_PATH + 1] = { 0 };
	TCHAR fileSystemName[MAX_PATH + 1] = { 0 };
	DWORD serialNumber = 0;
	DWORD maxComponentLen = 0;
	DWORD fileSystemFlags = 0;
	if (GetVolumeInformation(
		_T("C:\\"),
		volumeName,
		ARRAYSIZE(volumeName),
		&serialNumber,
		&maxComponentLen,
		&fileSystemFlags,
		fileSystemName,
		ARRAYSIZE(fileSystemName)))
	{
		std::cout << "Volume Name: " << volumeName << std::endl;
		std::cout << "HDD Serial: " << serialNumber << std::endl; 
		std::cout << "File System Type: " << fileSystemName << std::endl;
		std::cout << "Max Component Length: " << maxComponentLen << std::endl;
	}

Retrieving the computer name, this is easily changeable by the user.

    	TCHAR computerName[MAX_COMPUTERNAME_LENGTH + 1];
	DWORD size = sizeof(computerName) / sizeof(computerName[0]);
	if (GetComputerName(
		computerName,
		&size))
	{
		std::cout << "Computer Name: " << computerName << std::endl;
	}

Retrieving the CPU hash.

    int cpuinfo[4] = { 0, 0, 0, 0 }; //EAX, EBX, ECX, EDX
    __cpuid(cpuinfo, 0);
    char16_t hash = 0;
    char16_t* ptr = (char16_t*)(&cpuinfo[0]);
    for (char32_t i = 0; i < 8; i++)
    hash += ptr[i];
    std::cout << "CPU Hash: " << hash << std::endl;
