Serpent encryption algorithm source code

md5是常用的加密算法，但是在vc中没有系统的类可以用。本程序完成了md5类，使用简单。不是国内网上流传的类。-md5 is a commonly used encryption algorithm, but in vc no class system can be used. This procedure was completed md5 categories, using a simple. Rather than domestic circulating online class.

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。

常用的密码算法，如RSA，MD2，MD5等，还包括简单的例程，很久以前写着玩的-commonly used cryptographic algorithms, such as RSA, MD2, MD5, also includes a simple routine, a long time ago wrote a play
