typedef  ULONG (WINAPI *RtlRandom_NTAPI)(PULONG Seed);
LPWSTR GenerateRandomNumbers(int Length) //生成指定长度的数字
{
	RtlRandom_NTAPI RtlRandom_s=NULL;
	RtlRandom_s=(RtlRandom_NTAPI)GetProcAddress(GetModuleHandle(L"NTDLL.DLL"),"RtlRandom");
	static wchar_t wctRndNumbers[512];
	ULONG Seed = GetTickCount();
	for (int i = NULL; i < Length; i++)
		_snwprintf(&wctRndNumbers[i], sizeof(wctRndNumbers) - 1, L"%d", RtlRandom_s(&Seed) % 9);
	return wctRndNumbers;
}

LPWSTR GenerateRandomLetters(int Length) //生成指定成都的字母
{
	static wchar_t wctRndLetters[512];
	RtlRandom_NTAPI RtlRandom_s=NULL;
	RtlRandom_s=(RtlRandom_NTAPI)GetProcAddress(GetModuleHandle(L"NTDLL.DLL"),"RtlRandom");
	ULONG Seed = GetTickCount();
	for (int i = NULL; i < Length; i++)
		wctRndLetters[i] = RtlRandom_s(&Seed) % 26 + 97;

	return wctRndLetters;
}

调用示范:
std::wcout<<GenerateRandomLetters(10)<<std::endl;
std::wcout<<GenerateRandomNumbers(10)<<std::endl;

输出结果:
