I want to password protect an .xlsx excel file using Apache POI.

I am using an older version (3.8) of POI in my application. So is there any work around available for it. I want to protect all the worksheets as well the workbook. I am able to protect the worksheets but workbook is not getting password protected.

    _I am using an older version of POI_ - you obviously understand that the version number matters. So why have you to posted the exact version you are using? – Boris the Spider Aug 09 '14 at 07:48

  • I've recently added a [patch](https://issues.apache.org/bugzilla/show_bug.cgi?id=51483) for various sheet protection settings, how about upgrading the poi version? – kiwiwings Sep 21 '14 at 16:58
