【軟體限制】：30天試用。

【作者宣告】：初學Crack，只是感興趣，沒有其它目的。失誤之處敬請諸位大俠賜教！

【破解工具】：TRW2000娃娃修改版、Ollydbg1.09、PEiD、W32Dasm 10修改版

―――――――――――――――――――――――――――――――――
【過程】：

暴風共享軟體管理器I.exe 無殼。Visual C++ 6.0編寫。

呵呵，分析完了後看到newlaos兄寫的《奇門遁甲演義V6.3》，發覺演算法很相似，再看看軟體的開發公司，哦，是一家的，“共享”了一套註冊演算法。看來函式影像大師、鼠到擒來等等同門軟體也是差不多了。

雖然註冊碼很長，但演算法基本的流程是一樣的，變換了引數而得到其它幾組註冊碼，所以我只是記錄了第一組的演算法過程。

使用者名稱：fly
試煉碼：12345-67890-ABCDE-FGHIJ-KLMNO

反彙編，看看參考，很容易就能找到下面的核心。
