MD5 (Message-Digest algorithm 5) is a widely used, partially insecure[1] cryptographic hash function with a 128-bit hash value. As an Internet standard (RFC 1321), MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files. An MD5 hash is typically expressed as a 32 digit hexadecimal number.

检查更改过的文件备份，节省操作时间。 按Ctrl+Alt+F9弹出界面菜单。 显示备份状态和文件大小次数。 当目的地址是网络时，需要帐户和密码。 当正在备份时可以按停止键停止备份。 暂时只有增量备份 备份时间设定，格式可以是 00.00.00 或者 00:00:00。 进程优先算法选中后不影响其他程序工作(默认)。 点击确定保存设定开始计时。 自动启动并计时开始。-inspection changes to the document backup, saving hours of operation. Press Ctrl-Alt-F9 pop-up menu interface. Show backup status and the number of file size. When the destination address of the network, need to account and password. When the backup is at the stop button can stop by the backup. Incremental backup is only temporary backup sets the time, format or can be 00.00.00 00:00:00. Priority algorithm process after the elections does not affect other procedures (default). Click OK to preserve set the timer. Automatically activated and start time.

目前，已经有不少的Sniff工具软件，如Windows环境下，最富盛名的工具是Netxray和Sniffer pro，用它们在 Windows环境下抓包来分析，非常方便。在UNIX环境下如Sniffit，Snoop，Tcpdump，Dsniff 等都是比较常见的。这里介绍一个用C语言和网络数据包和分析开发工具libpcap及winpcap实现的简易网络Sniffer。-Currently, there have been numerous Sniff software tools, such as the Windows environment, the most famous tool is the Sniffer pro Netxray and use them in the Windows environment capturing Packet analysis, very convenient. In the UNIX environment as Sniffit, Snoop, Tcpdump, such as Dsniff are relatively common. Presented here with a C language and network packet analysis and the development of tools to achieve libpcap and winpcap Simple Network Sniffer.
