原帖地址：https://www.kechuang.org/t/66589首先应novakon的要求，在这里将贴出程序VB源代码。但是，曾听过不止一个DIY圈内的人说KC有山寨现象（即抄袭后拿去商业化、或者若干种嘚瑟用途），在帖子内的源代码我故意设置了不少bug，有数值的，也有逻辑的，有說出來的，也有沒說的。相信如果是编程高手，这方面的“武德”不会太差，毕竟写出来这东西不知道能用于什么用途，可大也可小，虽然它仅仅是个对称算法。如果有人能消化我的注解，就算不用看源代码自己也能写出一个99%类似的。不看注解的，就慢慢啃“生肉”吧。（我的是红烧芥末德国肉肠，在香肠机上转的那种，很快大家会知道为什么了。）
初步验证一下我的工具它的有效性，这里附上一个小题目。到上面地址中下载那个工具，如果缺少控件请看该贴二楼，然后运行主程序minen.exe

1.rar 200.32KB RAR 14次下载

题目密钥：223 152 145 56 220 100 45 88 179 2，看看是不是Hello, world!（这里有个程序bug，在后面无法输入220的时候，请先按一下size setting，因为尺寸大小导致了取模运算直接进行。
如果验证完了，可以尝试自己加解密一些纯文字信息。注意ASCII和Unicode开关，中文只能用Unicode模式。

好了，废话少说，贴上源代码。
