【详细过程】
不久前分析过它的2.0版，前几天作者对软件进行了升级，算法也改了，只好重新分析一下。虽然算法改了，但有很多东西没改，有了2.0版的分析作基础，问题就好解决得多了。
1.脱壳＋去自检验
查壳，仍然是UPX的壳，脱壳后可看到是VB的程序，运行一下照样会关机，看来自校验和2.0版的没多大变化。还是下断rtcFileLen,F9运行，可找到如下几处自校验的地方：
......
0055CA22 BF 0A000000 MOV EDI, 0A ; EDI=0x0a
0055CA27 897D B4 MOV DWORD PTR SS:, EDI
0055CA2A 8D4D B4 LEA ECX, DWORD PTR SS:
0055CA2D 51 PUSH ECX
0055CA47 FF15 DC104000 CALL DWORD PTR DS:[<&MSVBVM60.rtcRandomNext>] ; 产生一个随机数

0055CA5F FF15 00134000 CALL DWORD PTR DS:[<&MSVBVM60.__vbaFpI2>] ; MSVBVM60.__vbaFpI2
0055CA65 8BF0 MOV ESI, EAX
0055CA67 8D4D B4 LEA ECX, DWORD PTR SS:
0055CA6A FF15 20104000 CALL DWORD PTR DS:[<&MSVBVM60.__vbaFreeVar>] ; MSVBVM60.__vbaFreeVar
0055CA70 0FBFC6 MOVSX EAX, SI
0055CA73 3BC7 CMP EAX, EDI ; 结果与0x0a比较（即与10比较）
0055CA75 0F87 33040000 JA 0055CEAE ; 这里改为JMP就可去除自校验
0055CA7B FF2485 30CF5500 JMP DWORD PTR DS: ; 根据结果跳向不同的分支（功能相同）
0055CA82 8B45 E0 MOV EAX, DWORD PTR SS:
0055CA85 50 PUSH EAX
0055CA86 FF15 CC124000 CALL DWORD PTR DS:[<&MSVBVM60.rtcFileLen>] ; 得到文件大小
0055CA8C 8945 BC MOV DWORD PTR SS:, EAX

0055CAA0 FF15 28134000 CALL DWORD PTR DS:[<&MSVBVM60.rtcLeftCharVar>] ; 得到文件大小的左边3位数
0055CAA6 C785 6CFFFFFF B>MOV DWORD PTR SS:, 1B2
0055CAB0 89B5 64FFFFFF MOV DWORD PTR SS:, ESI
0055CAB6 8D45 A4 LEA EAX, DWORD PTR SS:
0055CAB9 50 PUSH EAX
0055CABA 8D8D 64FFFFFF LEA ECX, DWORD PTR SS:
0055CAC0 51 PUSH ECX
0055CAC1 8D55 94 LEA EDX, DWORD PTR SS:
0055CAC4 52 PUSH EDX
0055CAC5 FF15 CC104000 CALL DWORD PTR DS:[<&MSVBVM60.__vbaVarXor>] ; 与0x1b2异或
0055CACB 50 PUSH EAX
0055CACC FF15 84104000 CALL DWORD PTR DS:[<&MSVBVM60.__vbaBoolErrVar>]; MSVBVM60.__vbaBoolErrVar
0055CAD2 8BF0 MOV ESI, EAX
0055CAD4 8D45 A4 LEA EAX, DWORD PTR SS:
0055CAD7 50 PUSH EAX
0055CAD8 8D4D B4 LEA ECX, DWORD PTR SS:
0055CADB 51 PUSH ECX
0055CADC 6A 02 PUSH 2
0055CADE FF15 40104000 CALL DWORD PTR DS:[<&MSVBVM60.__vbaFreeVarList>] ; MSVBVM60.__vbaFreeVarList
0055CAE4 83C4 0C ADD ESP, 0C
0055CAE7 66:3BF3 CMP SI, BX
0055CAEA 0F84 BE030000 JE 0055CEAE ; 异或结果为0,这里就会跳
......
程序先产生一个1～10内的随机数，根据这个数的大小跳向不同的分支（但完成同样的功能：检验文件有无被脱壳）。这里0x1b2为未脱壳前文件大小的左边3个数字，就是说运行程序的大小与未脱壳文件的大小相等时就会跳走，不等就会继续执行到错误的分支。同样的还有0055CB73、0055CCC9 、0055CD76、0055CDFF四处，将这五处JE都改为JMP就可除去自校验（或改0055CA75处JA为JMP一处即可）。这时你就可以放心大胆地对它进行开刀了，想怎么玩就怎么玩：）
2.注册

4.小结
从上面这段程序可看出，运行程序后它先判断自己有没有被脱壳，被脱壳就调用“快速关机”功能（这本身是该软件的一个功能），然后再计算机器码，并将其变形后写入注册表中，然后查找有没有注册文件X:\FXSYS\FXSYS.KEY，有就对其进行解密（xor 0xfb)并将解密结果存入临时文件X:\FXSYS\FXSYS.TMP中，然后打开FXSYS.TMP文件，将其中的4行内容读出分别进行判断：
第1行＝
第2行＝机器码
第3行＝用户名
第4行＝注册码
5.算法总结
注册码格式：第4部分－第3部分－第2部分－第1部分
1）第1部分与0x22b9（十进制数8889）比较大于等于就行,即第1部分≥22B9
2）第2部分要同时满足005624AB和005626B5两处就必须是大于0xC379（十进制数51001）的数
3）机器码前3字符的ASIIC码累加再加1后与机器码从第4位起后的各位字符ASIIC码累乘，得数A
4）A开方取结果右边5位（注意精度，好象是LONG）得数B，A开方结果×11001取整得数C
5）（C XOR D XOR 第2部分）－第2部分，得数D
6）（用户名各字符ASIIC码×所在位数的平方＋用户名长度）XOR 第2部分，结果替换“用户名长度”后循环，直到用户名所有字符取完，得结果E
7）E×2转为十六进制数后反转即为注册码第3部分
8）（用户名各字符ASIIC码×用户名长度×所在位数＋1）XOR 第2部分，结果替换“1”后循环，直到用户名所有字符取完，得结果F
9）D与F第2位起的10位数异或，再与F第3位起的10位数异或，再与F的第1位数异或，结果转为十六进制数后反转即为注册码的第4部分

[ 本帖最后由 dewar 于 2007-6-7 11:36 编辑 ] 厲害，有時間再慢慢跟著練練 佩服！！！这软件都搞定了！！！ 老大，看雪不让发注册机，您就发发慈悲在PYG首发下注册机啊！！！ 厲害，有時間再慢慢跟著練練 出新版本了2.81.
这里热情放送注册号,限10名
要的贴出机器码和注册名 学习了，有时间试试 最新版本貌拟2.82了..
不过算法好像又改了=.=|| 机器码：319145
