EXCEL VBA工程密码破解方法（不破坏原密码）

发表于 2017-2-8 14:06:39

　　这种方法实际是避开VBA工程密码验证，即，骗vba编辑器，该密码输入成功，请求放行。
　　原理不多说了，先将方法公布：
　　===================================================
　　1.新建一个工作簿，打开，按ALT+F11，进入vba代码编辑器窗口：
　　2.新建一个模块，“插入”--“模块”把以下代码复制进模块并保存
　　---------------------------------------------------------------------------------------

Option Explicit
Private Declare Sub MoveMemory Lib "kernel32" Alias "RtlMoveMemory" (Destination As Long, Source As Long, ByVal Length As Long)
Private Declare Function VirtualProtect Lib "kernel32" (lpAddress As Long, ByVal dwSize As Long, ByVal flNewProtect As Long, lpflOldProtect As Long) As Long
Private Declare Function GetModuleHandleA Lib "kernel32" (ByVal lpModuleName As String) As Long
Private Declare Function GetProcaddress Lib "kernel32" (ByVal hModule As Long, ByVal lpProcName As String) As Long
Private Declare Function DialogBoxParam Lib "user32" Alias "DialogBoxParamA" (ByVal hInstance As Long, ByVal pTemplateName As Long, ByVal hWndParent As Long, ByVal lpDialogFunc As Long, ByVal dwInitParam As Long) As Integer
Dim HookBytes(0 To 5) As Byte
Dim OriginBytes(0 To 5) As Byte
Dim pFunc As Long
Dim Flag As Boolean
Private Function GetPtr(ByVal Value As Long) As Long
GetPtr = Value
End Function
Public Sub RecoverBytes()
If Flag Then MoveMemory ByVal pFunc, ByVal VarPtr(OriginBytes(0)), 6
End Sub
Public Function Hook() As Boolean
Dim TmpBytes(0 To 5) As Byte
Dim p As Long
Dim OriginProtect As Long
Hook = False
pFunc = GetProcAddress(GetModuleHandleA("user32.dll"), "DialogBoxParamA")
If VirtualProtect(ByVal pFunc, 6, &H40, OriginProtect) <> 0 Then
MoveMemory ByVal VarPtr(TmpBytes(0)), ByVal pFunc, 6
If TmpBytes(0) <> &H68 Then
MoveMemory ByVal VarPtr(OriginBytes(0)), ByVal pFunc, 6
p = GetPtr(AddressOf MyDialogBoxParam)
HookBytes(0) = &H68
MoveMemory ByVal VarPtr(HookBytes(1)), ByVal VarPtr(p), 4
HookBytes(5) = &HC3
MoveMemory ByVal pFunc, ByVal VarPtr(HookBytes(0)), 6
Flag = True
Hook = True
End If
End If
End Function
Private Function MyDialogBoxParam(ByVal hInstance As Long, _
ByVal pTemplateName As Long, ByVal hWndParent As Long, _
ByVal lpDialogFunc As Long, ByVal dwInitParam As Long) As Integer
If pTemplateName = 4070 Then
MyDialogBoxParam = 1
Else
RecoverBytes
MyDialogBoxParam = DialogBoxParam(hInstance, pTemplateName, hWndParent, lpDialogFunc, dwInitParam)
Hook
End If
End Function

复制代码

　　-------------------------------------------------------------------
　　3.右击sheet1工作表，“查看代码”复制以下代码进去并保存：
　　-------------------------------------------------------------------

sub 破解()
if hook then msgbox "破解成功"
end sub
sub 恢复()
RecoverBytes
msgbox "恢复成功"
end sub

复制代码

　　
　　
　　------------------------------------
　　4.到此,一个vba破解程序完成了,回到该工作簿窗口,文件-打开打开需要破解vba工程密码的工作簿.
　　5.运行call 破解稍后你再双击刚才要解密的VBA工程窗体.是不是如入无人之境啊,工程保护密码形同虚设啊?！
　　6.破解完成后,请右键刚破解的VBA工程,在查看工程时需要密码的地方复选框取消选择,OK.完成。再把该工作薄另存一下，即相当于有了一个没有vba密码的工作薄了。
　　7.最后执行call 恢复,恢复密码保护，这样，原来有vba工作密码的工作薄下次再打开的时候，又恢复了原来的密码。

最后如果对于上面的操作觉得太麻烦，那么可以直接下载下面这个破解文件即可。在sheet1里面点击"vba破解"即可。
