Accessing Password-Protected VBA Projects

When tasked with updating Excel 2003 macros, you may encounter password-protected VBA projects. These protections are often in place to secure critical code and functionality within the macros. However, without proper documentation or known passwords, accessing and updating these VBA projects can become a significant challenge.

In such scenarios, finding a way to remove or bypass the password protection becomes essential. This guide explores potential methods to unlock these VBA projects, enabling you to perform necessary updates and modifications to the macros, even when the original passwords are unknown.

Command	Description
Hex Editor	A tool used to view and edit the raw bytes of a file. It allows for direct manipulation of binary data within the file.
zipfile.ZipFile	A Python module used for reading and writing ZIP files, enabling extraction and compression of files within a ZIP archive.
shutil.copyfile	A Python method for copying the contents of a file to another file, useful for creating backups before making changes.
os.rename	A Python function that renames a file or directory, essential for changing file extensions and managing file names during processing.
ActiveWorkbook.VBProject	A VBA object representing the active workbook's VBA project, allowing access to its components and properties.
VBComponents	A collection of VBA components within a project, including modules, forms, and class modules, used for iterating and modifying properties.
Properties("Password").Value	A property of a VBA component that holds its password. Setting this value to an empty string removes the password protection.
zip_ref.extractall	A method in the zipfile module that extracts all the contents of a ZIP file to a specified directory.

Unlocking Password-Protected VBA Projects in Excel 2003

The scripts provided are designed to help users unlock password-protected VBA projects in Excel 2003, a common challenge when documentation is missing and passwords are unknown. The first method involves using a Hex Editor, which allows direct manipulation of the binary data within the Excel file. By renaming the Excel file extension from .xls to .zip, you can extract its contents and access the vbaProject.bin file. Within this file, you search for the DPB string and modify it to DPx (where x is any character). This change tricks Excel into thinking the project is unprotected, allowing access without the original password. Recompressing the files and renaming the extension back to .xls completes the process.

The second script utilizes VBA code to remove the password. By accessing the ActiveWorkbook.VBProject object, it iterates through the VBComponents collection. For each component, the script sets the Properties("Password").Value to an empty string, effectively removing the password protection. This method is straightforward but requires initial access to the VBA editor. The third script employs Python, using modules like zipfile.ZipFile for handling ZIP archives and shutil.copyfile for creating backups. The script extracts the contents of the Excel file, modifies the vbaProject.bin file by replacing the DPB string, and recompresses the files. These methods provide robust solutions for accessing password-protected VBA projects, ensuring you can update and maintain your macros even without the original passwords.

Removing Password Protection from Excel VBA Projects Using Hex Editor

Using a Hex Editor to Bypass VBA Passwords

Step 1: Make a backup of your Excel file.
Step 2: Change the file extension from .xls to .zip.
Step 3: Extract the contents of the .zip file.
Step 4: Open the extracted file with a Hex Editor (e.g., HxD).
Step 5: Locate the 'vbaProject.bin' file and open it.
Step 6: Search for the DPB string within the file.
Step 7: Change DPB to DPx (x can be any character).
Step 8: Save the changes and close the Hex Editor.
Step 9: Re-compress the files into a .zip and rename to .xls.
Step 10: Open the Excel file, the VBA project should be unprotected.

Using VBA Code to Remove Password from Excel VBA Project

Executing VBA Code to Unlock VBA Projects

Sub RemoveVbaPassword()
   Dim vbaProj As Object
   Set vbaProj = ActiveWorkbook.VBProject
   Dim vbaComps As Object
   Set vbaComps = vbaProj.VBComponents
   For Each vbaComp In vbaComps
       vbaComp.Properties("Password").Value = ""
   Next vbaComp
   MsgBox "VBA Password Removed"
End Sub

Using Python to Crack Excel VBA Project Password

Python Script for VBA Password Recovery

import zipfile
import os
from shutil import copyfile
 <code>def remove_vba_password(excel_file):
    backup_file = excel_file.replace(".xls", "_backup.xls")
    copyfile(excel_file, backup_file)
    os.rename(excel_file, excel_file.replace(".xls", ".zip"))
    with zipfile.ZipFile(excel_file.replace(".xls", ".zip"), 'r') as zip_ref:
        zip_ref.extractall('extracted')
    with open('extracted/xl/vbaProject.bin', 'rb') as file:
        data = file.read()
    data = data.replace(b'DPB', b'DPx')
    with open('extracted/xl/vbaProject.bin', 'wb') as file:
        file.write(data)
    with zipfile.ZipFile(excel_file.replace(".xls", ".zip"), 'w') as zip_ref:
        for folder, subfolders, files in os.walk('extracted'):
            for file in files:
                zip_ref.write(os.path.join(folder, file), os.path.relpath(os.path.join(folder, file), 'extracted'))
    os.rename(excel_file.replace(".xls", ".zip"), excel_file)
    print("Password Removed, backup created as " + backup_file)

Additional Methods for Accessing Password-Protected VBA Projects

Beyond the methods previously discussed, another effective approach involves utilizing third-party software specifically designed to unlock VBA projects. These tools are often more user-friendly and provide a straightforward interface for removing passwords. However, it’s important to ensure that the software is reputable and secure, as using untrusted sources can pose significant security risks. Popular tools for this purpose include Password Lastic and VBA Password Bypasser, which are designed to target and remove the protection from VBA projects within Excel files.

Additionally, another technique involves using an older version of Excel to open the file. Excel 95, for example, has different security mechanisms, and sometimes opening a file in an older version and then resaving it can strip out some of the newer protection methods. This approach is less technical and doesn't require additional software, making it accessible for users with minimal programming knowledge. However, it may not work for all types of password protection, particularly those implemented in more recent versions of Excel.
