超級電腦伴侶 V1.12演算法流程,另有問題請教大家! (32千字)
超級電腦伴侶 V1.12
使用者名稱:powerboy
機器碼:1181312697122788555
註冊碼:2149539941815962387068573381168434743
軟體的註冊演算法部分用到了一些不常用的運算指令(只是我見的比較少)用到了立方和進位迴圈的指令,演算法
流程不是很麻煩!脫殼後可以用DEDE很容易找到演算法的部分!
(最近正在從98平臺轉移到XP下進行破解發現DEDE和OLLYDBG真的很方便,以前在98下基本只用SICE,根本沒有發現他們的長處.透過這段時間的使用深有體會阿~!在這裡感謝寫DEDE的xxxx和漢化OLLYDBGxxxxx兄弟的勞動!)

演算法流程:
首先對使用者名稱的每位進行處理,然後分別儲存成10進位制在連線;
powerboy-> B0 AC AF 96
9A 7F 7F 7A
變10進位制連線:176172175150154127127122
在最後連線機器碼:176172175150154127127122+1181312697122788555
1761721751501541271271221181312697122788555然後對這個新字串進行運算
從第1位開始取5位變成十六進位制
17617->$44D1
然後進行3次方運算EAX儲存低8位,EDX儲存高8位
LF($44D1)=4F905B39971:
EAX=05B39971;EDX=000004F9
ESI=000053F7,EAX=0B7D772E,ECX=0,EDI=0,EDX=0,EBX=00006ECB
然後進行一次進位迴圈左移64位RCL(LF($44D1))=21495($53F7)
儲存最後的高位資料,最後把每次運算的結果變10進位制在連線;
$53F7=21495

很可惜進位迴圈的部分我不能用程式設計模擬(水平太差,也沒有時間思考...)所以序號產生器不能完成.
不知道各位誰有時間可以跟蹤一下然後給出進位迴圈的原始碼^_^謝了!
這幾日單位的事情非常之多,而且工作壓力還特別的大~!所以想找一個軟體分析一下,作為鬆弛神經的方法.
不知道各位有什麼好的辦法給自己減壓啊!告訴小弟幾招阿~小弟不勝感激~!
