1.输入用户名:Killer(转成大写后HEX为 4B 49 4C 4C 45 52)
软件内部有一字符串:YOU BE SLICK(HEX为59 4F 55 20 42 45 20 53 4C 49 43 4B)
将用户名与此字符串的HEX相减,差乘3后累加起来.
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即第一组数字的前3位
2.第一组数字的第4位计算过程
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余数为3,A-3=7 7+30=37

3.第2组数字的计算过程
到此注册码为: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余数为4F
2D-20=D  D*2=1A 1A+4F=69  69除67余数为2
32-20=12 12*3=36 36+2=38  38除67余数为38
36-20=16 16*4=58 58+38=90  90除67余数为29
37-20=17 17*5=73 73+29=9C  9C除67余数为35
37-20=17 17*6=8A 8A+35=BF  BF除67余数为58
2D-20=D  D*7=5B 5B+58=B3  B3除67余数为4C
4C+20=6C  6C(HEX)=108(D)
