EXE二合一源代码!不用多说了!用tasm编译!-source code! Needless to say! With Tasm compiler!

MD消息摘要程序，MD5以512位分组来处理输入的信息，且每一分组又被划分为16个32位子分组，经过了一系列的处理后，算法的输出由四个32位分组组成，将这四个32位分组级联后将生成一个128位散列值。-MD news summary procedures, MD5 to 512 groups to deal with the importation of information and each group was divided into 16 groups of 32 seats, after a series of processing, the output from the algorithm four groups composed of 32, these four sub-32 will generate a cascade 128 the hash value.

用MFC实现的对任意长度的文件的MD5加密，得到的是标准的32位十六进制数-Using MFC to achieve for any length of document MD5 encryption, receive the standard 32-bit hexadecimal number

LZW编码是围绕称为词典的转换表来完成的。这张转换表用来存放称为前缀(Prefix)的字符序列，并且为每个表项分配一个码字(Code word)，或者叫做序号。这张转换表实际上是把8位ASCII字符集进行扩充，增加的符号用来表示在文本或图像中出现的可变长度ASCII字符串。扩充后的代码可用9位、10位、11位、12位甚至更多的位来表示。
