说明：  网络安全与密码学技术，用qt作为界面，利用md5算法实现的文件防篡改程序。(Network security and cryptography, using qt as an interface, use the file md5 algorithm tamper program.)

wsk是win7上取代tdi驱动进行网络编程的技术，程序对wsk的接口进行封装，可以像应用层一样进行socket编程。(wsk is substituted on win7 tdi driven network programming techniques, procedures for wsk interface package, socket programming can be the same as the application layer.)

VB开发的IP测试程序，这是在我工作中写的调试程序，在配置文件中只需要写上相应的IP，程序就会循环测试IP地址是否在线，不在线的话就会报警提醒(VB development of IP test program, which is written in my work debugger, just write in the configuration file on the corresponding IP, the program will loop test IP address is online, not online, then it will alarm to remind)

程序可以获取本机IP地址，需要先加载Socket库(Program can access the machine IP address, need to load the Socket Library)

There is no souse code. Just trash

11mh的辅助源码，下载研究去吧！！！！(Source of the 11mh the secondary, download study go! ! ! !)

这是一个用于局域网内部进行聊天通信的小软件源程序，对于学习和了解winsock编程很有借鉴意义。(This is a chat for LAN communications within a small software source code, for learning and understanding of referential significance to winsock programming.)

1.局域网内设备IP搜索 2.发送广播包出去，同时启动侦听接收 3.支持局域网内跨网断搜索(1.IP search in local network 2.send broadcast packet, and receive request 3.support different gateway.)

用MFC 开发的基于UDP协议的网络科学计算中心,比较适用于局域网内(Using MFC development agreement based on the UDP network Scientific Computing Center, more applicable to the LAN)

网络内容过滤系统，使用中间层驱动过滤IP，LSP过滤URL和关键字！(Text content, url, URL, ip filter voice prompts can be issued according to the text, and fast alarm 3 software set certain security measures to protect and prevent tampering and unauthorized access 4. Through illegal information characteristics to upgrade the feature library.)
