获取主机的硬件信息，CPU的ID，MAC，以及硬盘的ID

前段时间给公司的软件加密，需要获取主机的一些硬件信息，从网上搜集得来的资料，忘记来源网址了，现在整理了记录以下：

一。获取CPU的ID

CString GetCpuId()
{
CString CPUID;
unsigned long s1,s2;
unsigned char vendor_id[]="------------";
char sel;

sel='1';
CString VernderID;
CString MyCpuID,CPUID1,CPUID2;
switch(sel)
{
case '1':
__asm{
xor eax,eax      //eax=0:取Vendor信息
cpuid    //取cpu id指令，可在Ring3级使用
mov dword ptr vendor_id,ebx
mov dword ptr vendor_id[+4],edx
mov dword ptr vendor_id[+8],ecx
}
VernderID.Format(_T("%s-"),vendor_id);
__asm{

mov eax,01h   //eax=1:取CPU序列号
xor edx,edx
cpuid
mov s1,edx
mov s2,eax
}
CPUID1.Format(_T("%08X-%08X"),s1,s2);
__asm{

mov eax,03h
xor ecx,ecx
xor edx,edx
cpuid
mov s1,edx
mov s2,ecx
}
CPUID2.Format(_T("-%08X-%08X"),s1,s2);
break;
case '2':
{
__asm{
mov ecx,119h
rdmsr
or eax,00200000h
wrmsr
}
}
AfxMessageBox(_T("CPU id is disabled."));
break;
}

MyCpuID = VernderID+CPUID1+CPUID2;
CPUID = MyCpuID;
return CPUID;
}

二。获取MAC

BOOL GetMacAddress(CString& strMacAddress)
{
BYTE szSystemInfo[4096]; // 在程序执行完毕后，此处存储取得的系统特征码
UINT uSystemInfoLen = 0;
UINT uErrorCode=0;
IP_ADAPTER_INFO iai;
ULONG uSize = 0;
DWORD dwResult = GetAdaptersInfo( &iai, &uSize );
CString MacAddress;
if( dwResult == ERROR_BUFFER_OVERFLOW )
{
IP_ADAPTER_INFO* piai=( IP_ADAPTER_INFO* )HeapAlloc( GetProcessHeap( ), 0, uSize );
if( piai != NULL )
{
dwResult = GetAdaptersInfo( piai, &uSize );
if( ERROR_SUCCESS == dwResult )
{
IP_ADAPTER_INFO* piai2 = piai;

CopyMemory(szSystemInfo+uSystemInfoLen,piai2->Address, piai2->AddressLength );
uSystemInfoLen += piai2->AddressLength;
for(int i = 0; i < uSystemInfoLen; i++)
{
MacAddress.Format("%02X", szSystemInfo[i]);
strMacAddress += MacAddress;
}
}
else
{
uErrorCode = 0xF0000000U + dwResult;
}
assert( HeapFree( GetProcessHeap( ), 0, piai ) );
}
else
{
return FALSE;
}
}
else
{
uErrorCode = 0xE0000000U + dwResult;
}
if( uErrorCode != 0U )
{
return FALSE;
}
return TRUE;
}

三。获取硬盘的ID

CString GetDiskSeriesNumber()
{
CString str;
DWORD Serial;
DWORD Length;
GetVolumeInformation(_T("C:\\"),NULL,MAX_PATH,&Serial,&Length,NULL,NULL,MAX_PATH);
str.Format("%X",Serial);
return str;
}

另外，要使以上函数能编译，必须#include <Iphlpapi.h>；
