Default Better protection for VBA project?

Hi All,

(I'm not a VBA pro, more of an enhusiastic amateur)


Is it possible to better protect a VBA project?

I wrote a simple trading sheet for a guy recently
and I put a bit of code in to disable the sheet after
a day or two until he paid me.

What he did though was ask about on a few forums
and got info on how to easily crack a VBA project security.

I tried it and it was alarmingy easy.

He got hold of a Hex editor and created a VBA project with
an easily recognisable password, say DOGBONE for example.

He then found where excel stored this password via the
hex editor, opened my sheet and with the hex editor replaced
my password with the simple one.

Lo and behold he had cracked my VBA project security in about
5 minutes.

Is there a better more secure way to protect a VBA project?

Thumbs up Answer: Better protection for VBA project?

Hi Ron,

I understand your concern about protecting your VBA project. There are a few steps you can take to make it more secure.
  1. Password protect your VBA project: You can password protect your VBA project by going to the VBA editor, clicking on "Tools" and then "VBAProject Properties". In the "Protection" tab, check the "Lock project for viewing" box and enter a password. This will prevent anyone from viewing or modifying your code without the password.
  2. Use a digital signatu You can sign your VBA project with a digital signature to ensure that it has not been tampered with. To do this, go to the VBA editor, click on "Tools" and then "Digital Signature". Follow the prompts to create and apply a digital signature to your project.
  3. Convert your VBA code to an add-in: You can convert your VBA code to an add-in, which is a separate file that can be loaded into Excel. This will prevent anyone from accessing your code directly. To do this, go to the VBA editor, click on "File" and then "Export File". Choose "Microsoft Excel Add-In" as the file type and save the file.
  4. Use third-party softwa There are third-party software programs available that can provide additional security for your VBA project. These programs can encrypt your code, add password protection, and more. Some popular options include VbaCompiler for Excel and XLS Padlock.

I hope these tips help you better protect your VBA project. Let me know if you have any questions or need further assistance.

Hi Ron,

Yes there is (misplaced the link to this one):

1. Save the Excel workbook (.xls) file into an add-in (File SaveAs.....)
2. After you have the saved add-in (.xla), close the Excel workbook (.xls)
3. Double click on the add-in to open it
4. Press Alt+F11 to access the add-in's vba project
5. Lock the vba-project with a password
6. Double-click on the "ThisWorkbook" code module
7. Press F4 to open the Properties window
8. Change the "IsAddin" status to FALSE
9. Return to Excel by Pressing Alt+Q (or close the vbe window)
10. Go to Tools Share Workbook
11. When the dialogue appears, check the box for: (Allow changes by.....)
12. Press OK to close the Dialogue
13. When prompted to save, Press OK
14. Press Ok to accept that "macros cannot be accessed"
15. You should feel giddy at this point because you just realized what you have
been missing right under your nose
16. Verify that the [SHARED] appears in the application title bar
17. Now save the workbook again as an Add-in (File SaveAs...) overwriting the
previous one
18. Close this Excel workbook without saving the changes (you don't need it)
19. Test out your newly saved add-in (open it, access the vbe, try to expand
the project window, you should get the new message "Project is Unviewable"
20. Your done

Jan, my spreadsheet uses XML data, so when I follow this procedure I
get an error at step 10 saying "This workbook cannot be shared because
it contains Excel tables or XML maps...". Is there any way of
protecting my VBA?

I got this to work once. Later when I updated the file, I got a message that
this was not a valid add-in? Thoughts? Thanks!

Best solution for the buck, IMO, I've ever found...

http://dombajsoft.com/protectvba.htm

...where it generates a protected copy for distributing and lets you
work with the original version in the normal fashion!

Displays "Project is unviewable" same as JKP's solution does, but not
'undoable' like JKP's is.

Unfortunately, I'll have to wait until I get home to look at it. My Work blocked that page.

However, using the code equivalent of JKP's solution I was able to get it to work (on 2007, haven't tried 2013):

Workbooks("test.xla").SaveAs "c:\test.xla", AccessMode:=xlShared

And so is undoable, allowing 'savy' users to 'break in'. The solution I
use requires binary editing of the file for do/undo and so not so easy
to 'break in' for most. Also lets me use 'version stamping' on the fly
so my install knows when it's upgrading vs updating apps that require a
license.

Unviewable+ VBA Projects for Excel & Powerpoint

http://spreadsheet1.com/unviewable-v...for-excel.html

An Unviewable VBA project cannot be defeated by numerous password hacking software, such as this password recovery add-in. The unviewable plus VBA application is NOT based on the old shared workbook trick, which is easy to overcome and cannot be created, if there are Tables in your workbook or add-in.

The software is an executable that will turn your add-in (or workbook) into an add-in (or workbook) with an unviewable VBA project. Besides Excel macro-enabled files, the unviewable+ application can also protect PowerPoint presentations.

This does same for all MS Office apps and most others that license VBA.
It only costs $20...

Hmm.., you appear to be correct. I don't know the status of the product
as I've been using it for some years and so not keeping track. I'm sure
contacting them will fix the situation!

Yes, I know this! I read extensively about Unviewable+ after a
recommendation by Chris Newman. It appears to modify the binary in the
same way PVC does, to render VBA projects unviewable!

PVC should be identical to Unviewable+ SIMPLE protection level. I believe that's where the similarities end. Certainly, it was a great program when it was first launched many years ago. Hacking methods have become more sophisticated since then, hence the need for a stronger protection.

It doesn't do anything else. It renders the same 'effect' as JKP's
shared workbook trick, (which as you probably know can be undone) by
altering the binary at various levels. Only admitted flaw to date is
that if you use the 'optional' advanced protection it loses a level
when you save your file. IMO, that degree of protection is overkill
anyway and so i not an issue with me!<g

My understanding is that the latest release of unviewable+ 'just
works'! I don't use it myself but I've done extensive work with another
monitor of these NGs (who is a MVP I will not name). I do know the
issues you cite are common with shared workbooks and so I suspect any
methodology that messes with anything to do with that feature will
cause trouble.

Of course, there's always the option to go DLL or COMAddin!

I did it about 7 years ago.
I moved all calculation logic to C++
Unfortunately a couple of things must stay in VBA or we simply do not
want client to add anything to VBA.

What I do is more like document facing project . File can be send around
the world.
I can't install anything. All VSTO or DLL requiring registration with
admin right can't be used.

Clients do not have rights to install anything.
They work on virtual desktops and every time they login they see brand
new computer. Nothing stays except data on shared drives.

They other reason is that they do not want to install anything.
They want to open excel file, do their work and send that file to
another person.
I call that iPhone syndrome. One button click and nothing more advanced.

Yes, I get that. My solution for portable apps (run from USB drive) is
to run DLLs reg-free via LoadLibrary(). No reason you can't do same
other than it requires you ship the DLL with your workbook. This
clearly won't work in your scenario!

Perhaps you can have someone using a current release unviewable+ lock
your VBA project so you can give it a test drive!?

Aplication.RegisterXLL
It solves a lot of problems with complicated calculation processes and
does not require any registration.

"Free" is not necessarily a bad thing. All of my publicly-available projects
have been released for free. (Also open source, a not-entirely-related
subject.)

I'm not willing to dig out the old thread just to get some context, but as a
general rule, why should I pay for something when there's something else just
as good (or almost so) that is free? It doesn't matter whether or not I can
afford it.

Hi Ron,

Is there a better more secure way to protect a VBA project?


Yes there is (misplaced the link to this one):

1. Save the Excel workbook (.xls) file into an add-in (File SaveAs.....)
2. After you have the saved add-in (.xla), close the Excel workbook (.xls)
3. Double click on the add-in to open it
4. Press Alt+F11 to access the add-in's vba project
5. Lock the vba-project with a password
6. Double-click on the "ThisWorkbook" code module
7. Press F4 to open the Properties window
8. Change the "IsAddin" status to FALSE
9. Return to Excel by Pressing Alt+Q (or close the vbe window)
10. Go to Tools Share Workbook
11. When the dialogue appears, check the box for: (Allow changes by.....)
12. Press OK to close the Dialogue
13. When prompted to save, Press OK
14. Press Ok to accept that "macros cannot be accessed"
15. You should feel giddy at this point because you just realized what you have
been missing right under your nose
16. Verify that the [SHARED] appears in the application title bar
17. Now save the workbook again as an Add-in (File SaveAs...) overwriting the
previous one
18. Close this Excel workbook without saving the changes (you don't need it)
19. Test out your newly saved add-in (open it, access the vbe, try to expand
the project window, you should get the new message "Project is Unviewable"
20. Your done

Default Better protection for VBA project?

It works for me. If you follow the steps given by Jan it works perfectly unless if you have tables or XML. May I know what is the error message that you get.. Thanks

Do you really think Jan is still waiting around for more replies to this
thread? (Hint: No.)
