XLS Padlock offers several security features.
⇒ Make your workbook accessible on one computer only, thanks to hardware-locked keys.
⇒ Make your workbook accessible only when a dongle or USB stick is inserted.
⇒ Control who can use your workbook thanks to the online activation and validation features.
Keep your formulas secret with formula protection.
Calculations will work, but users will not have access to your formulas.
Disable the Formular Bar.
Secure your sensitive VBA code thanks to the Excel VBA compiler of XLS Padlock.
Stop access to the VBA Project by locking your project or preventing access to the Visual Basic Editor.
You have several options to prevent some usual user actions:
XLS Padlock lets you decide if you want your users to be able to save their changes in your Excel workbook or not.
→ If you disallow saving, your workbook will never be modified.
→ If you allow saving, your original workbook will still always be accessible. Changes will be saved in another crypted file that can only be opened with your secure application.
When you digitally sign a compiled workbook EXE file (this is called code signing), you ensure end users that the code within the EXE file they are to receive has not been tampered with or altered.
Thanks to XLS Padlock, it is easy to sign your .exe files since XLS Padlock handles everything itself. SHA-256 code signing is supported!
These limitations can be set if you use activation keys (simple or hardware-locked) or dongle protection. Just choose the appropriate options and deliver keys to your end users (trial or registered ones):
→ a given number of days
→ a given date.
Note: VBA programmers can determine whether the workbook is in trial state thanks to XLS Padlock VBA API code extensions.
