同学编写的小软件，MD5编码器



md5的全称是message-digest algorithm 5。md5将对输入的任意长度的信息进行计算，产生一个128bit长度的大整数，并且它是一个不可逆的变换算法，至于它的原理，有兴趣的朋友可以自己上网查找相关资料。



md5的典型实际应用是对一段message(字节串)产生“指纹”，可以防止文件被人“篡改”。



使用介绍：

[choose ]：选择待加密文件；

[encrypt]：对选定文件进行加密运算；

[ save ]：以*.md5.txt（*：指原文件）的形式把“指纹”保存在原文件的目录下。-students prepared by the small software MD5 encoder md5 name is message-digest algorithm 5. Md5 will import of arbitrary length of the information, have a length of 128 bit integers, and it is an irreversible transformation algorithm as its principle, the friends are interested in their own Internet search relevant information. Md5 typical practical application of a message (byte string) to "fingerprint" that could prevent the document were "distorted." Use introduced : [choose] : choice question encryption; [Encrypt] : selected documents encryption algorithms; [Save] : md5.txt*. (* : refers to the original documents) in the form of the "fingerprints" preserved in the original document directory.
