如果Excel文件的打开密码忘记了,且密码是6位数以内的数字,可用以下步骤解开(关掉所有程序,为了速度):
新开一Excel,同时按Alt和F11,进入7a64e58685e5aeb9339VBA界面,点菜单上的插入,模块,在新出来的窗口粘贴一下代码:
Sub crack()
Dim i As Long
Dim FileName As String
i = 0
FileName = Application.GetOpenFilename("Excel文件(*.xls & *.xlsx),*.xls;*.xlsx", , "VBA破解")
FileName = Right(FileName, Len(FileName) - InStrRev(FileName, "\"))
Application.ScreenUpdating = False
line2: On Error GoTo line1
Workbooks.Open FileName, , True, , i
MsgBox "Password is " & i
Exit Sub
line1: i = i + 1
Resume line2
Application.ScreenUpdating = True
End Sub
然后在此界面直接按F5运行此宏,选择文件,等啊等(看密码长度了)
Sub MoveProtect()
Dim FileName As String
FileName = Application.GetOpenFilename("Excel文件(*.xlsm & *.xlam),*.xlsm;*.xlam", , "VBA破解")
If FileName = CStr(False) Then
Exit Sub
Else
VBAPassword FileName, False
End If
End Sub
Private Function VBAPassword(FileName As String, Optional Protect As Boolean = False)
If Dir(FileName) = "" Then
Exit Function
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
MsgBox "请先对VBA编码设置一个保护密码...", 32, "提示"
Exit Function
End If
If Protect = False Then
Dim St As String * 2
Dim s20 As String * 1
'取得一个0D0A十六进制字串
Get #1, CMGs - 2, St
'取得一个20十六制字串
Get #1, DPBo + 16, s20
'替换加密部份7a64e78988e69d83365机码
For i = CMGs To DPBo Step 2
Put #1, i, St
Next
'加入不配对符号
If (DPBo - CMGs) Mod 2 <> 0 Then
Put #1, DPBo + 1, s20
End If
MsgBox "文件解密成功......", 32, "提示"
Else
Dim MMs As String * 5
MMs = "DPB="""
Put #1, CMGs, MMs
MsgBox "对文件特殊加密成功......", 32, "提示"
End If
Close #1
End Function
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e799bee5baa6e79fa5e98193e59b9ee7ad94336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 Explicit
Private 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
重装一遍excel,正版的
