在WTL程序中使用MD5算法的一个实现例子。

c++实现密钥为4的凯撒密码加密，其中支持明文的大小写-c++ achieve key for Caesar 4 password encryption, which supports the explicit case

文件中有说明,本程序主要提供了MD5算法的功能实现!-Document has indicate that this procedure provides the main function of MD5 algorithm realize!

128位(或192或256bit该代码以128为例)的密钥长度和分组长度，数据分组（输入的明文），先进行逐比特异或（AddRoundKey） 运算。然后通过循环十次非线性代换（SubBytes）、行变换（ShiftRows）、列变换（MixColumns）、逐比特异或【最后一轮不进行列变换】 的过程，输出128位（或192或256bit）数据即是密文。这就是加密过程。之后进行之前的逆过程，即可得到明文，此为解密过程。

et框架由于拥有CLR提供的丰富库支持，只需很少的代码即可实现先前使用C等旧式语言很难实现的加密算法。本类实现一些常用机密算法，供参考。其中MD5算法返回Int的ToString字串。返回数字字母型结果的算法参见之前Blog文章-* This program is free software you can redistribute it and/or modify it * under the terms of the GNU General Public License as published by the * Free Software Foundation either version 2, or (at your option) any * later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
