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.

主要功能： 1.可以搜索局域网内的所有工作组和计算机； 2.利用了win2k的net send 功能。可以向对端直接发送桌面消息，对端不 用有该程序； 3.可以查看对方的共享资源； 4.可以直接登录对方计算机，可以建立空连接； 5.可以点对点的进行语音通话； 6.可以匿名发送消息； 7.可以传送文件，（最好是小于10M的文件，这个功能还没有优化好）；-main functions : 1. LAN can search all the working group and the computer; 2. Win2k use of the net send function. To be sent directly to end desktop news is not right side of the proceedings; 3. View can share each other"s resources; 4. The other side can be directly logged in the computer, we can establish air links; 5. Could the point-to-point voice calls; 6. Anonymous information can be sent; 7. documents can be transmitted, (preferably less than 10M of the document, and the optimization feature is not good);

　各个线程任务分配是这样实现的。在开始下载时，文件平均分成若干块进行下载。如第一个线程一开始的任务是从文件的0位置开始下载一直到72908位置处。线程1每次下载一块数据后就要调整任务，如第一次下载了20800字节的数据，那么线程1的任务将改为：20800-72908。如此下去，直到任务为72908-72908时表示线程1完成了当前的下载任务。此时，线程1就分析各个线程的任务，找出任务最为繁忙的一个线程：如线程3：14816-218724。那么线程1就自动去调整任务，拿50%的任务来再次下载。周而复始直到各个线程都完成任务。不过这里有一点需要注意：为了避免重复下载部分数据，在调整任务的时候，起始的文件便移量必须加上接受缓冲器的字节数，因为如前面所举的列子来看。线程1和线程3在平衡负载的时候，线程正在下载数据，如果所剩的数据比接受缓冲器的大小还小，线程1和线程3的部分下载数据将会重复。 　　在调整任务和分析任务的时候，会发现一个问题。就是读取文件数据太过频繁。于是我用了一个数据结构。在下载文件的过程中始终打开配置文件，这样速度提高了很多。在文件下载完毕后关闭文件。-various threads assignment is achieved. At the beginning of the download, the paper divided into a number of pieces of the download. As a thread of a task is to start from the position paper of 0 to start the download has 72,908 locations Department. Thread a download each one will have to adjust the data tasks, such as the first downloaded 20,800 gigabytes of data, then threaded a task will be re :20800- 72908. This situation continues until the mandate of 72908-72908 said threaded a completion of the cu
