【文章标题】: Win Image Converter 加法运算，也算走完个过程
【文章作者】: ella
【软件名称】: Win Image Converter V1.5.2
【下载地址】: http://www.pearlmountainsoft.com/win-image-converter-download.html
【保护方式】: UPX
【作者声明】: 凑热闹~^_^
--------------------------------------------------------------------------------
【详细过程】
1，去掉UPX
2，开始，输入注册码：IMGCT-00213-01913-05B12-04412，来到关键的地方
主程序里：
004032D0 55 push ebp
004032D1 8BEC mov ebp, esp
004032D3 6A FF push -1
............................略
00403394 FF15 5C104100 call dword ptr [<&albumdesigncore.CRegisterUtility::CheckCode>] ; >> &)>
0040339A 84C0 test al, al
0040339C 74 5F je short 004033FD ; 跳向提示失败
进 00403394 来到：
10028C90 >/$ 8B5424 04 mov edx, dword ptr [esp+4]
10028C94 |. 8D41 08 lea eax, dword ptr [ecx+8]
10028C97 |. 8B49 04 mov ecx, dword ptr [ecx+4]
10028C9A |. 50 push eax

10028CA2 |. 83C4 0C add esp, 0C
10028CA5 \. C2 0400 retn 4
验证是在DLL里的，进10028C9D call ; albumdes.CheckRandomSerialCode

3，回顾加法运算
a,注册码是否为29位
b,0x5,0xB,0x11,0x17是否为“-”
c,前5位是否为IMGCT
d,0x6~0xA 加0x11~0x16对应的整数是否为05D25,0xc~0x10 加0x18~0x1D对应的整数是否为05D25
4，注册机
4.1 C版部分代码，骗人的，因为相加等于固定数，只是让它取相应的字符，组成注册码～！
void GenSerial(HWND hWnd)
{
int len;
int i,j,p,q;
char szName[MAX_NAME+1];
char szSerial[MAX_SERIAL]={"IMGCT-00213-01913-05B12-04412"};
char szRand1[14]={"0123456789ABCD"};
char szRand2[6]={"012345"};
char szRand3[3]={"012"};
srand((unsigned int)(time(0)));
i=rand()%5;
j=rand()%13;
p=rand()%2;
q=rand()%5;
szSerial[7]=szRand2[i];
szSerial[19]=szRand2[5-i];
szSerial[8]=szRand1[j];
szSerial[20]=szRand1[13-j];
szSerial[9]=szRand3
;
szSerial[21]=szRand3[2-p];
szSerial[10]=szRand2[q];
szSerial[22]=szRand2[5-q];
i=rand()%5;
j=rand()%13;
p=rand()%2;
q=rand()%5;
szSerial[13]=szRand2[i];
szSerial[25]=szRand2[5-i];
szSerial[14]=szRand1[j];
szSerial[26]=szRand1[13-j];
szSerial[15]=szRand3
