Settting Passworf for HSSFWorkBook

HI , 

   is anyone know how to protect workbook/sheet using POI ?
   I believe HSSFWorkBook only can protect the sheet using no password which
anyone can unprotect it

   is there any tutorial/good url teaching us how to generate Excel using
WorkBook ( Low Level Api )
   simply because i want to protect workbook/sheet with some password and
dont let anyone tamper it.

    Or can it be done using HSSFWorkBook?

   Thanks

Hi
Do u meant for POI HSSFWorkBook only or even for WorkBook there is no way to
protect the workbook/sheet using password?
because i can see there is few methods in WorkBook such as CreatePassword()
and so on?
can we use it?

Thanks

This isn't supported. To protect a workbook with a password, you have to 
encrypt it. We can't find any documentation on how the encryption process 
works, so we can't add it to POI.
