首先以下方案只针对 Word 文档和 Excel 文档的 VBA 工程密码。
打开一个 Excel 的程序实例(无论待破解的是什么文档一律打开 Excel 实例),按 Alt + F11 打开 VBE,左侧“工程资源管理器”右键新建一个模块,复制下列代码粘贴进去后定位至过程 VBA_Password_remove 按 F5 运行选择要破解的包含工程密码的文件。
Option ExplicitPrivate Sub VBA_Password_remove()
Dim Filename As String, i As Integer
Filename = Application.Caption
If InStr(Filename, "Excel") > 0 Then
Filename = openfile()
Else
MsgBox "请在 Microsoft Office Excel Visual Basic of Application 环境下运行本程序!", vbExclamation
Exit Sub
End If
If (Filename = "False") Then Exit Sub
If Dir(Filename) = "" Then
MsgBox "未找到指定文件"
Exit Sub
Else
FileCopy Filename, Filename & ".bak"
End If
Dim GetData As String * 5
Open Filename For Binary As #1
Dim CMGs As Long
Dim DPBo As Long
For i = 1 To LOF(1)
Get #1, i, GetData
If GetData = "CMG=""" Then CMGs = i
If GetData = "[Host" Then DPBo = i - 2: Exit For
Next
If CMGs = 0 Then
Close #1
MsgBox "VBA 工程未设置密码", vbQuestion, "提示"
Exit Sub
End If
Dim St As String * 2
Dim s20 As String * 1
Get #1, CMGs - 2, St
Get #1, DPBo + 16, s20
For i = CMGs To DPBo Step 2
Put #1, i, St
Next
If (DPBo - CMGs) Mod 2 <> 0 Then Put #1, DPBo + 1, s20
MsgBox "文件解密成功!", vbQuestion, "提示"
Close #1
End Sub
Function openfile()
openfile = Application.GetOpenFilename("Excel 文件(*.xls & *.xla & *.xlt),*.xls*.xla*.xlt,Word 文件(*.doc & *.dot ),*.doc*.dot", , "选择破解 VBA 工程密码的文件")
End Function
