Editor's review

Worried about unapproved users entering and reading the data you keep in your created Excel documents? Worry no more! LockXLS 1.0 allows the safety of your Excel documents by creating trial ware of your documents and allowing for encryption of the documents as well.

This program is pretty useful and is very user-friendly. The data in your spreadsheets will be safe if you choose to encrypt it because it shall be encrypted with a secure 128-bit algorithm. Your spreadsheets can be locked with passwords, trial periods, and hardware based keys. The formulas and the VBA code of the Excel document become invisible so a client will not be able to analyze the logic of the document.

As an extra random feature, a personalized message can be added to locked content. Also, this product boasts that protected excel worksheets will load just as quickly as if they weren`t locked. All in all, this seems like one of the more useful Excel add-ons.

LockXLS

George, or who uses this nick, you`ve retyped old review on several websites, which describes already resolved issue. This is proven by our customers - you can see their reviews. Your efforts are senseless. You can retype same report once again using another nickname, but more and more customers give up another products like DoneEx and switch to LockXLS.

By courtesy of WhiteHatXL, I reproduce part of his review dedicated to LockXls
PROS: The tool is programmed in C++. In protected solution everything works like in original workbook. Average user cannot see formulas in cells and vba code in protected workbook. Protects xla files. Lots of features.
CONS: The product uses unmodified, original workbooks in protected solutions and relies on hackers’ methods to take customer away from seeing the content of the workbook (Hooks Excel windows and blocks Excel’s COM objects methods calls). The tool is trying to stub all Excel’s security breaches, which is impossible with an unmodified, original workbook.
When a protected solution has been started on an end customer computer, the spreadsheet becomes as unprotected as newborn baby.
5 lines of C code extract the original workbook from the protected solution, doesn’t matter whether it’s xls or exe file.
To prove the vulnerability of LockXLS solutions, just e-mail a protected solution to WhiteHatXL at yahoo dot com, the original workbook will be returned.
SUMMARY: Fake. This product is not for a workbook protection.
