VBA工程加密PJ方式(两种)

两种方式破解VBA加密代码

第一种：

Sub VBAPassword1() '你要解保护的Excel文件路径

Filename = Application.GetOpenFilename("Excel文件（*.xls & *.xla & *.xlt）,*.xls;*.xla;*.xlt", , "VBA破解")

If Dir(Filename) = "" Then

MsgBox "没找到相关文件,清重新设置。"

Exit Sub

Else

FileCopy Filename, Filename & ".bak" '备份文件。

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 Sub

End If

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"

Close #1

End Sub

第二种：
