//.用户名不参与计算；
//.注册码必须用“-”连接，长度不限；
//.注册码前六位必须是ALLDJVC；
//.注册码形式：ALLDJVC-XXXX-YYYY-ZZZZ；
//.注册码分四个单元，第一个单元固定，每个单元之间用短横线“-”分开，计算时只取每个注册码单元的前四位；
//.软件名称：AllDJVideoConverter；
V的十六进制数=56；
56÷（13-5）=L……Sn1；
d的十六进制数=64；
64÷（13-7）=M……Sn2；
o的十六进制数=6F；
6F÷（13-9）=N……Sn3；
//.XXXX÷13=A……Sn1，（XXXX指第二单元注册码前四位ASCII码十六进制之和，A随意）；
//.YYYY÷13=B……Sn2，（YYYY指第三单元注册码前四位ASCII码十六进制之和，B随意）；
//.ZZZZ÷13=C……Sn3，（ZZZZ指第四单元注册码前四位ASCII码十六进制之和，C随意）。
//.Serial Number:
Name：yAtEs
Code：ALLDJVC-101A-101C-1098
//.注册表信息：
Windows Registry Editor Version 5.00
"DiscountDate"=hex:00,00,00,00,60,b2,e3,40
"RegName"="yAtEs"
"SN"="ALLDJVC-101A-101C-1098"
不错噢！楼主 Alldj Video Converter算法分析 By：yAtEs 2010.6.10

请问是楼主原创分析吗?怎么每次发帖的名字不一样? 是楼主的原创！
