**************************************************************
一、运行程序，进行注册，输入错误的注册信息进行检测，有提示信息
"Invalid user name or register code"
**************************************************************
二、用PEiD对AVI MPEG WMV RM to MP3 Converter.exe查壳，为 MoleBox V2.3X -> MoleStudio.com * Sign.By.fly [Overlay] *
**************************************************************
三、带壳调试，运行OD，打开AVI MPEG WMV RM to MP3 Converter.exe，用F12暂停后再查找字符串.

【破解总结】
--------------------------------------------------------------
【算法总结】
主要采用RSA算法
注册码形式如下：
11111111-22222222-33333333-44444444-55555555-66666663-77777777-88888888
sn1 sn2 sn3 sn4 sn5 sn6 sn7 sn8
运算过程中注册码作下面的变形
sn8' = (sn5 + sn4 + sn3 + sn2) xor sn8
sn7' = (sn1 + sn6) xor sn7
变形后的注册码
sn'=sn1-sn2-sn3-sn4-sn5-sn6-sn7'-sn8'
=======================================================
用RSATool计算RSA参数
n=p*q:
n:AC68F21CE8AF587FD0AD17300B69D083A6E08D8669BFDD46BD0341A8BBA18BE9
p:CDAAA985DD8FDC9397544BC5A4629CEF
q:D69AB2EA765881E2D17A8598A29D94A7
e:10001
d:46B6C49716D8D4739823665F4E4F18363ADB6C46A2AEC054B234CFD9B9FC741
=======================================================
举例说明：
用户名:tianxj，ASCII码为7469616E786A
则：X=786A00007469616E <------ m
Y=46B6C49716D8D4739823665F4E4F18363ADB6C46A2AEC054B234CFD9B9FC741 <------ d
Z=AC68F21CE8AF587FD0AD17300B69D083A6E08D8669BFDD46BD0341A8BBA18BE9 <------ n
用Bigclc“X^Y%Z”计算出C (基数选16)
C=1D212B983F5B1ED8F47BB13445AA974DD11DA613F6F1E77B8DD229B59C7C69E9
格式化"%08lX-%08lX-%08lX-%08lX-%08lX-%08lX-%08lX-%08lX"形式为
1D212B98-3F5B1ED8-F47BB134-45AA974D-D11DA613-F6F1E77B-8DD229B5-9C7C69E9
倒转9C7C69E9-8DD229B5-F6F1E77B-D11DA613-45AA974D-F47BB134-3F5B1ED8-1D212B98
计算：s7=(s6+s1) xor s7' =190F81B1D xor 3F5B1ED8 = 1AFA305C5
s8=(s5+s4+s3+s2) xor s8' =29B8C4E90 xor 1D212B98 = 286AD6508
注册码: 9C7C69E9-8DD229B5-F6F1E77B-D11DA613-45AA974D-F47BB134-AFA305C5-86AD6508
