Subject Re: DO NOT REPLY [Bug 48900] XSSF doesn't have the method protectSheet as we have for HSSF API
Date Mon, 15 Mar 2010 16:46:55 GMT

This may well sound completely stupid but have you tried using a template
file yet? It may - and that is a big may - be possible to use Excel to
create a template file that is password protected. Then you could open that
file using POI, populate it with data and re-save it away again. I know that
POI passes through anything that it does not recognise and it may well do
the same with this sort of tempate file. If I have the chance later, I will
try it myself to see what happens, after all, what can we lose?

Yours

PS, the bit of the SpreadsheetML that Yegor is talking about contains the
password for the file but it has been encrypted in some manner. In fact, it
looks something like this;

<sheetProtection password="83AF" sheet="1" objects="1" scenarios="1"
formatCells="0" /> 

where the string 83AF is the password 'password' after encryption.

The best thing you could do would be to conduct some research to find out if
you could identify the encryption algorithm. That sort of information
may/will help the developers to more rapidly address this issue.
