【管他正版盗版的】Woo咚加密算法程序 Pascal版

本Pascal版使用Delphi2009编译，因此对Unicode支持是很不错的，能够支持非英文字符的加密。
原算法参见 http://poketb.com/woodu/2010/04/04/789-published-the-answer/comment-page-1/
程序是在使用Unicode的前提下写的，若使用不支持Unicode的编译器重新编译可能导致对非英文字符的识别产生错误，所以慎重。

还有，我都不知道该怎么说了
目前没发现不兼容VB版的地方
坐等W挑刺

Delphi 2009+Windows 7 Ultimate下通过
