註冊碼類軟體
設斷點bpx hmemcpy
中斷後按F12鍵12次(第15次出錯)後,按F10鍵若干次,用D EAX便可看到註冊碼
註冊碼格式:BM-****-***
以下是註冊碼生成過程:
1.輸入使用者名稱:Killer(轉成大寫後HEX為 4B 49 4C 4C 45 52)
軟體內部有一字串:YOU BE SLICK(HEX為59 4F 55 20 42 45 20 53 4C 49 43 4B)
將使用者名稱與此字串的HEX相減,差乘3後累加起來.
59-4B=E E*3=2A 2A+0=2A
4F-49=6 6*3=12 12+2A=3C
55-4C=9 9*3=1B 1B+3C=57
4C-20=2C 2C*3=84 84+57=DB
45-42=3 3*3=9 9+DB=E4
52-45=D D*3=27 27+E4=10B
10B(HEX)=267(D) 267即第一組數字的前3位
2.第一組數字的第4位計算過程
37-30=7 7*3=15 15+0=15
36-30=6 不乘3 6+15=1B
32-30=2 2*3=6 6+1B=21
21(HEX)除A餘數為3,A-3=7 7+30=37
3.第2組數字的計算過程
到此註冊碼為:BM-2677-***(HEX:42 4D 2D 32 36 37 37 2D)
42-20=22 22+0=22
4D-20=2D 2D*1=2D 2D+22=4F 4F除67餘數為4F
2D-20=D D*2=1A 1A+4F=69 69除67餘數為2
32-20=12 12*3=36 36+2=38 38除67餘數為38
36-20=16 16*4=58 58+38=90 90除67餘數為29
37-20=17 17*5=73 73+29=9C 9C除67餘數為35
37-20=17 17*6=8A 8A+35=BF BF除67餘數為58
2D-20=D D*7=5B 5B+58=B3 B3除67餘數為4C
4C+20=6C 6C(HEX)=108(D)
整理後
使用者名稱:Killer
註冊碼:BM-2677-108
使用者名稱:LiuTong
註冊碼:BM-3964-100
破解註冊碼生成過程時,很費勁,差一點就放棄了.
