xplorer2之破解和序號產生器
【物件】xplorer2 V1.1.0.2，http://www2.skycn.com/soft/21143.html
【軟體簡介】xplorer2是2xExplorer的後續版本，xplorer2擁有全新、非常友好 的介面，和Windows的資源管理器一模一樣的操作，讓你不用學習即 迅速上手。
■>>>> xplorer2體積小巧，卻提供相當前衛、個性、豐富的功能：
①很有創意的“臨時碎片容器”，用過了才知道爽不爽！
②擁有一個目錄視窗，兩個瀏覽視窗，可以大圖示、詳細資訊等方式檢視檔案(跟Windows的完全一樣！用過Total Commander、EF Commander嗎，也是雙視窗，但它們顯示的圖示較小，用xplorer2就好啦！)
③支援快速書籤，批次重新命名，方便的快捷鍵。
④強大的檔案搜尋功能，直觀地統計目錄資訊讓你看個明明白白，提供檔案的分割/合併/永久刪除等功能。
⑤可即時預覽文字及眾多型別的多媒體檔案（需要相應系統外掛支援，建議安裝暴風影音，等）。
⑥極好的命令列執行功能，內建DOS控制檯，跑DOS命令再無需啟動黑視窗！
⑦隨時隨地的提示資訊，上手極快。
⑧附帶有一個不錯的文字編輯器，比Windows記事本強多了。
⑨沒有FTP等雞肋型功能(怎麼說還是FlashFXP專業！)，等等...
總之，這是一款功能豐富、介面簡潔、操作簡單、身材相當苗條的增強型檔案管理器！

首先用peid看一看，呵呵無殼，VC++。不要高興得太早
這邊要注意：你在程式中下斷點看看（記憶體斷點也算），你會聽到咚咚咚三下（或者死的不明不白）
說明程式中有校驗部分，校驗使得跟蹤更難，爆破不行。當然你可以除去它
但是在這裡我想給出序號產生器，不用暴力，所以忍了。
先隨便輸入字串試試，它會提示你字串要~200（其實就是200）云云
找到它，如下：
.text:0043F1CF Sub_PreProcessKey proc near ; CODE XREF: sub_43EF3C+A9p
.text:0043F1CF
.text:0043F1CF Var_Handle = dword ptr -4
.text:0043F1CF Arg_0C = word ptr 0Ch
.text:0043F1CF
.text:0043F1CF push ebp
.text:0043F1D0 mov ebp, esp
.text:0043F1D2 push ecx
.text:0043F1D3 cmp [ebp+Arg_0C], 1
.text:0043F1D8 push ebx
.text:0043F1D9 push esi

.text:0043F1DB mov edi, ecx

.text:0043F1E3 mov eax, dword_46AB68
.text:0043F1E8 push 47Ah ; nIDDlgItem
.text:0043F1ED push dword ptr [edi+4] ; hDlg
.text:0043F1F0 mov [ebp+Var_Handle], eax
.text:0043F1F3 call ds:GetDlgItem
.text:0043F1F9 mov ebx, eax
.text:0043F1FB lea eax, [ebp+Var_Handle]
.text:0043F1FE push eax
.text:0043F1FF push ebx
.text:0043F200 call sub_43278B
.text:0043F205 pop ecx

.text:0043F207 lea ecx, [ebp+Var_Handle]
.text:0043F20A call sub_401BA2
.text:0043F20F lea ecx, [ebp+Var_Handle]
.text:0043F212 call sub_405DF2
.text:0043F217 mov esi, offset word_46FDAC
.text:0043F21C lea ecx, [ebp+Var_Handle]
.text:0043F21F push esi
.text:0043F220 push offset asc_46D6C4 ; "\n"
.text:0043F225 call sub_41874D
.text:0043F22A push esi
.text:0043F22B push offset asc_46B070 ; "\t"
.text:0043F230 lea ecx, [ebp+Var_Handle]
.text:0043F233 call sub_41874D
.text:0043F238 push esi
.text:0043F239 push offset asc_46DFB0 ; "\r"
.text:0043F23E lea ecx, [ebp+Var_Handle]
.text:0043F241 call sub_41874D
.text:0043F246 push esi
.text:0043F247 push offset asc_46AFDC ; " "
.text:0043F24C lea ecx, [ebp+Var_Handle]
.text:0043F24F call sub_41874D
以上是從你輸入的字元中去掉'\n','\t','\r',' '.
.text:0043F254 mov ecx, [ebp+Var_Handle]
.text:0043F257 mov eax, [ecx-8]
.text:0043F25A test eax, eax
.text:0043F25C jz short loc_43F297
.text:0043F25E mov edx, 0C8h
.text:0043F263 cmp eax, edx
.text:0043F265 jnz short loc_43F2B6
比較長度是否為0xC8=200，不是則錯
由於程式不能預先下斷點，所以一切都要等要求註冊的對話方塊出來後（即校驗完畢後）再下
.text:0043F267 xor esi, esi

.text:0043F307
在這邊，註冊碼是對是錯程式透過postmessage到訊息處理處統一處理------這樣我們斷下最後的錯誤提示資訊就沒有用了，因為我們根本不知道是哪段發出的訊息
這樣我們只能我們在keys記憶體處設斷，慢慢的分析每個記憶體斷點處
終於找到了一個比較有價值的地方

0038FAFA C2 0C00 retn 0C
由此我們可以得出序號產生器演算法
key符合下列條件
1.第8位=1
2.從第4位開始的4個char組成一個int在0x1C42F0F和0x1D2D9A0之間並且不等於給定字串的前4個char組成的int（0x98989898）
3.從0A開始取出值p[a]，再以該值為偏移量得到零一個值p[b]，p[b]^m[i] ==p[b+1],a = b+2,繼續進入迴圈
4.上面的每個p[a]的值之間的距離大於2，並且在0xA-0x62之間
下面給出序號產生器的程式碼：在這個程式碼中我只算出了一組key。當然你可以改一下算出所有key
#include <stdio.h>
void main()
{
char p[100];
char q[201] = {0};
char t[20];
int a = 0x0a;//a的初始值
char b = 0x1f;//我把它從0x1f開始，0x1f在0xA-0x62之間
char m[] = "\xA5\x5D\x12\xE4\x37";\\這時程式初始化的值
for(int i = 0; i < 100; i ++)
p[i] = (char)0x88;//沒事就用88來填
for (i = 0; i < 5; i ++)
{
p[a] = b;
p[b + 1] = p[b] ^ m[i];//上面的第三的條件
a = b + 2;
b = b + 8;//第四個條件，我讓他們相差8〉2
}
p[4] = 0x11;
p[5] = 0x11;
p[6] = 0x0D1;
p[7] = 0x01;//這4個值組成0x1d11111在0x1C42F0F和0x1D2D9A0
p[8] = 1;//這個值必須為1
//下面是hentostr轉化，方法很土，其實可以仿照他的程式中strtohen
for(i = 0; i < 100; i ++)
{
sprintf(t,"%02X",p[i]);
if((unsigned int)p[i] >= 0x80)
{
q[2 * i] = t[6];
q[2 * i + 1] = t[7];
}
else
{
q[2 * i] = t[0];
q[2 * i + 1] = t[1];
}
}
//存放在檔案中
FILE *fp = fopen("C:\\key.dat","w");
if(NULL == fp) return ;
fprintf(fp,"%s",q);
fclose(fp);
}
至此，分析完畢！
