万一你的街区 没有发生= \ r \ nDPB“XXXX”=“XXXXX”\ r \ nGC =“XXXXXX” 如果您的“已知密码”文件比“未知密码”文件中的现有块短，请用后面的零填充十六进制字符串以达到正确的长度。

e.g.

CMG=“xxxxxx”\r\nDPB=“xxxxx”\r\nGC=“xxxxx”

在未知密码文件中，应设置为

CMG="XXXX00"\r\nDPB="XXXXX000"\r\nGC="XXXXXX0000"保留文件长度。

我在office 2007中也使用过。xla(97/2003格式)文件。

ElcomSoft提供高级办公密码破断器和高级办公密码恢复产品，只要文档是在Office 2007或更早版本中创建的，就可以适用于这种情况。

编辑:这是已接受答案的更新版本，应该适用于更多的办公室版本。这很难，但让我们把这个答案说出来吧!

轮到我了，这是建立在kaybee99的优秀答案之上的，它建立在Đức Thanh nguykun的出色答案之上，允许这种方法与32/64位版本的Office一起工作。

概览一下更改的内容，我们避免了push/ret，它仅限于32位地址，并将其替换为mov/jmp reg。

它是如何工作的

Open the file(s) that contain your locked VBA Projects. Create a new file with the same type as the above and store this code in Module1 Option Explicit Private Const PAGE_EXECUTE_READWRITE = &H40 Private Declare PtrSafe Sub MoveMemory Lib "kernel32" Alias "RtlMoveMemory" _ (Destination As LongPtr, Source As LongPtr, ByVal Length As LongPtr) Private Declare PtrSafe Function VirtualProtect Lib "kernel32" (lpAddress As LongPtr, _ ByVal dwSize As LongPtr, ByVal flNewProtect As LongPtr, lpflOldProtect As LongPtr) As LongPtr Private Declare PtrSafe Function GetModuleHandleA Lib "kernel32" (ByVal lpModuleName As String) As LongPtr Private Declare PtrSafe Function GetProcAddress Lib "kernel32" (ByVal hModule As LongPtr, _ ByVal lpProcName As String) As LongPtr Private Declare PtrSafe Function DialogBoxParam Lib "user32" Alias "DialogBoxParamA" (ByVal hInstance As LongPtr, _ ByVal pTemplateName As LongPtr, ByVal hWndParent As LongPtr, _ ByVal lpDialogFunc As LongPtr, ByVal dwInitParam As LongPtr) As Integer Dim HookBytes(0 To 11) As Byte Dim OriginBytes(0 To 11) As Byte Dim pFunc As LongPtr Dim Flag As Boolean Private Function GetPtr(ByVal Value As LongPtr) As LongPtr GetPtr = Value End Function Public Sub RecoverBytes() If Flag Then MoveMemory ByVal pFunc, ByVal VarPtr(OriginBytes(0)), 12 End Sub Public Function Hook() As Boolean Dim TmpBytes(0 To 11) As Byte Dim p As LongPtr, osi As Byte Dim OriginProtect As LongPtr Hook = False #If Win64 Then osi = 1 #Else osi = 0 #End If pFunc = GetProcAddress(GetModuleHandleA("user32.dll"), "DialogBoxParamA") If VirtualProtect(ByVal pFunc, 12, PAGE_EXECUTE_READWRITE, OriginProtect) <> 0 Then MoveMemory ByVal VarPtr(TmpBytes(0)), ByVal pFunc, osi+1 If TmpBytes(osi) <> &HB8 Then MoveMemory ByVal VarPtr(OriginBytes(0)), ByVal pFunc, 12 p = GetPtr(AddressOf MyDialogBoxParam) If osi Then HookBytes(0) = &H48 HookBytes(osi) = &HB8 osi = osi + 1 MoveMemory ByVal VarPtr(HookBytes(osi)), ByVal VarPtr(p), 4 * osi HookBytes(osi + 4 * osi) = &HFF HookBytes(osi + 4 * osi + 1) = &HE0 MoveMemory ByVal pFunc, ByVal VarPtr(HookBytes(0)), 12 Flag = True Hook = True End If End If End Function Private Function MyDialogBoxParam(ByVal hInstance As LongPtr, _ ByVal pTemplateName As LongPtr, ByVal hWndParent As LongPtr, _ ByVal lpDialogFunc As LongPtr, ByVal dwInitParam As LongPtr) As Integer If pTemplateName = 4070 Then MyDialogBoxParam = 1 Else RecoverBytes MyDialogBoxParam = DialogBoxParam(hInstance, pTemplateName, _ hWndParent, lpDialogFunc, dwInitParam) Hook End If End Function Paste this code in Module2 and run it Sub unprotected() If Hook Then MsgBox "VBA Project is unprotected!", vbInformation, "*****" End If End Sub

Colin Pickard is mostly correct, but don't confuse the "password to open" protection for the entire file with the VBA password protection, which is completely different from the former and is the same for Office 2003 and 2007 (for Office 2007, rename the file to .zip and look for the vbaProject.bin inside the zip). And that technically the correct way to edit the file is to use a OLE compound document viewer like CFX to open up the correct stream. Of course, if you are just replacing bytes, the plain old binary editor may work.

顺便说一句，如果你想知道这些字段的确切格式，他们现在有文档:

我的工具VbaDiff直接从文件中读取VBA，因此您可以使用它从大多数办公文档中恢复受保护的VBA代码，而无需求助于十六进制编辑器。

保护是Excel中的一个简单的文本比较。 在你最喜欢的调试器中加载Excel (Ollydbg是我选择的工具)，找到进行比较的代码并将其修复为总是返回true，这应该可以让你访问宏。
