Windows用户层使用指令操作内核程序执行指令! (10) 应用程序入口和演示

我们终于能够开始我们的主题了,关于应用程序怎么写.可以根据自己的需要如后台运行执行进程保护指令让自己的进程无敌都可以,以下为代码

LyService.cpp:

#include <iostream>
#include <string>

#include "driverInit.h"
#include "encryption.h"

#define debugMode false

HANDLE hDevice = nullptr;

int init();

void menu() {
	printf("1. Get data\n");
	printf("2. Send data\n");
	printf("3. Exit\n");
}

void test() {
	int choice = 0;
	while (choice != 3) {
		menu();
		std::cin >> choice;
		switch (choice) {
		case 1:
		{
			std::string data;
			data = read_kernel_service(1024);
			std::cout << "Received data: " << data << std::endl;
			break;
		}
		case 2:
		{
			std::string data;
			std::cout << "Enter data to send: ";
			std::cin.ignore();
			getline(std::cin, data);
			std::string encryptedData = encryption::encrypt(data);
			std::string result = data + encryptedData;
			write_kernel_service(result, result.length());
			break;
		}
		case 3:
			exit(0);
			break;
		default:
			std::cout << "Invalid choice" << std::endl;
			break;
		}
	}
}

int main(int argc, char* argv[]) {

	if (init() != 0 && debugMode == false) {
		return 1;
	}
	test();
	return 0;
}

int init() {
	hDevice = CreateFileA(
		"\\\\.\\LyKernelService",
		GENERIC_READ | GENERIC_WRITE,
		0,
		nullptr,
		OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL,
		nullptr
	);
	if (hDevice == INVALID_HANDLE_VALUE) {
		CloseHandle(hDevice);
		std::cout << "Failed to open device" << std::endl;
		return 1;
	}
	return 0;
}

我们正式的结束了!接下来为软件部分测试:

先对驱动签名就行,可以向微软申请签名,

文件属性即签名
