--------------------------------------------------------------------------------
【详细过程】
下面算是本人分析笔记：首先用PEID查壳，UPX 0.89.6 - 1.02 / 1.05 - 1.24 -> Markus & Laszlo，窃喜，这种老壳大侠的脱壳工具都早做好了，不过为练习下，手动脱下看，顺利的话比找工具脱要快，好了，开始，用OD载入主程序如下

007E07A0 >  60             pushad
  007E07A1 BE 00A06A00    mov    esi, 006AA000
  007E07A6 8DBE 0070D5FF lea    edi, dword ptr [esi+FFD57000]
  007E07AC 57             push edi
  007E07AD 83CD FF       or    ebp, FFFFFFFF
  007E07B0 EB 10          jmp    short 007E07C2
  007E07B2 90             nop
  007E07B3 90             nop
  007E07B4 90             nop
  007E07B5 90             nop
  007E07B6 90             nop
  007E07B7 90             nop
  007E07B8 8A06          mov    al, byte ptr [esi]
  007E07BA 46             inc    esi
  007E07BB 8807          mov    byte ptr [edi], al
  007E07BD 47             inc    edi
  007E07BE 01DB          add    ebx, ebx
  007E07C0 75 07          jnz    short 007E07C9
  007E07C2 8B1E          mov    ebx, dword ptr [esi]

  呵呵，典型的特征码，既然有pushad那定有popad,点右键查找命令--输入 popad 查找到了这

  007E08E6 57             push edi
  007E08E7 48             dec    eax
  007E08E8 F2:AE          repne scas byte ptr es:[edi]
  007E08EA 55             push ebp
  007E08EB FF96 046D3F00 call dword ptr [esi+3F6D04]
  007E08F1 09C0          or    eax, eax
  007E08F3 74 07          je    short 007E08FC
  007E08F5 8903          mov    dword ptr [ebx], eax
  007E08F7 83C3 04       add    ebx, 4
  007E08FA  ^ EB E1          jmp    short 007E08DD
  007E08FC FF96 086D3F00 call dword ptr [esi+3F6D08]
  007E0902 61             popad                                  ; 找到这,下断
  007E0903  - E9 408EEBFF    jmp    00699748
  007E0908 2009          and    byte ptr [ecx], cl
  007E090A 7E 00          jle    short 007E090C
  007E090C 3009          xor    byte ptr [ecx], cl
  007E090E 7E 00          jle    short 007E0910
  007E0910 AC             lods byte ptr [esi]
  007E0911 A0 69000000    mov    al, byte ptr [69]

  这样明显的跳转指令， - E9 408EEBFF    jmp    00699748 奔向OEP，不用说了，就是OEP啦，不放心的再按B查找看看还别的没有POPAD，没找到，只有这一个，好了，F2下断007E0902，再按F4或F9运行断下，取消断点，按F8，到达OEP

  00699748 55             push ebp                      到此点右键DUMP此进程
  00699749 8BEC          mov    ebp, esp
  0069974B B9 07000000    mov    ecx, 7
  00699750 6A 00          push 0
  00699752 6A 00          push 0
  00699754 49             dec    ecx
  00699755  ^ 75 F9          jnz    short 00699750
  00699757 53             push ebx
  00699758 56             push esi
  00699759 57             push edi
  0069975A B8 B08E6900    mov    eax, 00698EB0
  0069975F E8 E8DED6FF    call 0040764C
  00699764 33C0          xor    eax, eax
  00699766 55             push ebp
  00699767 68 FF9A6900    push 00699AFF

  运行DUMP出来的程序，正常，点系统注册，晕倒，出现错误了，不出机器码，看来要OVERLY数据了，弄了半天，没找到什么原因，也没修复

好，算了，投降，用大侠脱壳工具看看，呵呵，运行正常点注册，机器码出现了，惭愧啊。好了，用PEID再查无壳，Borland Delphi 6.0 - 7.0语言编写。  用OD载入脱壳后程序如下

  00699748 > $  55          push ebp
  00699749 .  8BEC       mov    ebp, esp

  00699766 .  55          push ebp

  点右键查找注册失败字符 “注册码不正确”只有一处，好了，双击定位来到主程序领空，往上追踪查看如下入口代码，F2下断

  汗！按F9运行，直接关机，看来还用反调试的代码呀，还好，这种关机代码容易查找，不管调用DOS关机指令还是其它什么关机函数，应该有shutdown 字符。
重启电脑，重新载入，点右键查找字符串，在字符串界面上点右键查找“shutdown”，呵呵，找到了，再按B 查找下一个，无，只有一处

【经验总结】
  本软件使用关机反调试及仿真代码CALL（是从网上查的，可能是仿真代码），按F7进入也都是虚拟地址，在CALL处按F8就跳出，调试起来有些麻烦的，不过一步一步来，也不是太难，算法并不复杂，还有那个壳手动脱了后运行其它都正常，只是点注册时不出注册码，不知何原因，补数据也不行，还得要努力学习才行
  好了，算法总结如下：分两段
第一，取机器码转成ASCII码，再用固定字符串"OFDSSDESDS"的ASCII码分别以第一组开始作十六进制双字节异或，异或结果再
  与下一组ASCII码异或。。。直到全部异或完，结果为C
  第二段，取注册码，与固定字符串"OFDSSDESDS"的ASCII码分别以相反顺序即先从最后一组的十六进制双字节作异或，异或结果
  再与下一组ASCII码异或。。。直到全部异或完，并把结果作为ASCII码转为字符串为D
  最后只要C=D就能注册成功，成功后软件具有完整功能。
  注册成功后在安装夹生成一个“备份.TXT“文件，并以一定格式写入CoTel.dll中，删除里面的信息，又可重注册，好了，
  算法出来了，用VB写个注册机：
  Private Sub Command1_Click()
  Dim a() As String, i As Integer
  Dim b() As String, j As Integer
  Dim c As String
  Dim d As String
  Dim m As String
  Dim t As String
  Dim s As String
  Dim u As String
  Dim v As String
  Dim w As String
  Dim x() As String
  Dim y() As String

  c = Text1.Text
  If c = "" Then Exit Sub
  For i = 0 To Len(c) - 1
  d = Hex(Asc(Mid(c, Len(c) - i, 1))) & " " & d
  Next i
  d = Trim(d)
  a = Split(d, " ")
  For i = 0 To UBound(a)
  If Len(a(i)) <> 2 Then MsgBox "输入的数据不对！": Exit Sub
  Next i
  m = "OFDSSDESDS"
  If m = "" Then Exit Sub
  For i = 0 To Len(m) - 1
  t = Hex(Asc(Mid(m, Len(m) - i, 1))) & " " & t
  Next i

  t = Trim(t)
  b = Split(t, " ")
  For i = 0 To UBound(b)
  If Len(b(i)) <> 2 Then MsgBox "输入的数据不对！": Exit Sub
  Next i

  For j = 0 To UBound(b)

  For i = 0 To UBound(a)

  a(i) = Val("&h" & a(i)) Xor Val("&h" & b(j))
  a(i) = Hex(a(i))

  Next i

  Next j

  For i = 0 To UBound(a)
  s = s & a(i)
  Next i

  For i = 0 To Len(s) - 1
  u = Hex(Asc(Mid(s, Len(s) - i, 1))) & " " & u
  Next i
  u = Trim(u)
  x = Split(u, " ")
  For i = 0 To UBound(x)
  If Len(x(i)) <> 2 Then MsgBox "输入的数据不对！": Exit Sub
  Next i
  m = "OFDSSDESDS"
  If m = "" Then Exit Sub
  For i = 0 To Len(m) - 1
  w = Hex(Asc(Mid(m, Len(m) - i, 1))) & " " & w
  Next i

  w = Trim(w)
  y = Split(w, " ")
  For i = 0 To UBound(y)
  If Len(y(i)) <> 2 Then MsgBox "输入的数据不对！": Exit Sub
  Next i

  For j = 0 To UBound(y)

  For i = 0 To UBound(x)

  x(i) = Val("&h" & x(i)) Xor Val("&h" & y(j))
  x(i) = Hex(x(i))

  Next i

  Next j

  For i = 0 To UBound(x)
  v = v & x(i)
  Next i

  Text2.Text = v
  End Sub

貌似经常看到你这样回复？

不可能，我就刚才看到别人这样回复的，感觉好猜用的

这样是不行的，会算恶意灌水的。一直这样刷帖是会被举报 1-2次还好。

感谢提醒。
