I was wondering about which one is harder to be breached penetrated to reverse its engineer and get the vba codes recorded in an application made on excel spreadsheet.
So, which one can really make it harder to be penetrated of getting its vba codes?
I do find that XLS padlock does has obfuscation to the vba codes which is sounding ok.
But the DoneEx seems to be doing obfuscation to be impossible to really be cracked by any reverse engineering?
I’m also trying to decide on whether to purchase. My thoughts are 1.) I see XLS Padlock released a new version today (news link below) that apparently separates the EXE from the data file and includes code signing. I wonder if that won’t be more secure if the VBA is isolated in the EXE, depending on how it is compiled? Not sure. 2.) I cannot find any verifiable commercial applications using XLS Padlock. Have you come across any?
In the new application bundle format, the VBA code is still in bytecode if you use the VBA compiler. It doesn’t have more weakness than in standalone EXE file. The main reason to choose the bundle format is for end users who don’t have a code signing certificate and get issues with some antivirus software.
They are some, but not sure whether we are allowed to publish their names. Feel free to send us a PM to have some references.
Thanks the code signing aspect is useful.
