Add zeroes on the end of the known macro password until it is the same length as the unknown macro password. ![]() Repeat steps 3-5 with the macro with the unknown password.ħ. Copy the value of this key, as shown below.Ħ. Open this macro in HxD and search for “DPB”.Ĥ. Create and save a new macro with a very short password, like the letter “a”.ģ. #VISUAL BASIC EDITOR PASSWORD CRACK INSTALL#Download and install HxD, which is a free and easy-to-use hex editor.Ģ. With Excel macros, it is sometimes necessary to modify all three keys (and sometimes in both places where they occur in the macro file), but the technique I am going to show you has worked for me when I modify only the first instance of the DPB key. We just need to know that this is where the password is stored. We don’t know what encryption algorithm Microsoft uses here and we don’t care. All three relate to the security mechanism, but, in particular, the DPB key contains the encrypted password. These three keys occur in two different places in the. The key word is “mostly” because if you look carefully, you will run into some metadata written in English that looks something like this:ĭPB=”5B59F77F6C9C6C9C93646D9C1EDAF1C91AF11C1729F7168075B76D9D66F46FEE731BC7DB9D” swp in Notepad, you’ll mostly see characters and symbols with no obvious meaning. SolidWorks VBA macros (.swp), as you probably know, are binary (non-text) files. Highlight the insecurity of VBA macros, thereby encouraging programmers who want to protect their source code to use. ![]() Help those with legitimate reasons to access the source code to do so more quickly.Ģ. Therefore, my purpose in writing this post is two-fold:ġ. For example, if the programmer leaves the company and the CAD manager needs to modify the macro, they will be forced to rewrite the macro or stop using unless they can access its source code. #VISUAL BASIC EDITOR PASSWORD CRACK CRACKED#Moreover, we have to keep in mind that just as a locked macro can be cracked for bad reasons, it can also be cracked for good reasons. #VISUAL BASIC EDITOR PASSWORD CRACK HOW TO#The steps I demonstrate here are simply adapted from StackOverflow posts explaining how to crack Excel VBA macros. “Wait, so aren’t you just making piracy easier by documenting how to crack VBA macros?”ĭoubtful. NET addin or stand-alone and use obfuscation alongside a password mechanism. If piracy is a concern, I recommend that you create your program as a. Second, VBA macros can be easily cracked, as this blog post will demonstrate. First, as mentioned, locking a macro doesn’t stop anyone from running it. This creates a neat little safeguard against tampering on the part of curious users, but it is not, in my opinion, a safeguard against piracy, for two reason. The password is required to view the source code but not run the macro. Any VBA macro, whether for SolidWorks or an Microsoft Office product, can have be locked using a password. NET, that allows developers to navigate, search, disassemble and analyze. For example, Reflector is a class browser and analysis tool for.
