Hello Ming, looks like our paths have finally crossed. :-)

The encryption work is already done.  The CWS is blocking for the other
feature, the sheet protection options, mostly on the ODF TC file format
change approval.  Once the file change is approved the missing piece of
ODF load/save can be implemented quite easily for that sheet protection
options feature.

Here is the proposal:

(Actually any help pushing my proposal on the ODF TC would be great,
since you guys are pretty active on the TC...)

Thanks for your offer, but since the core encryption work is 99%
complete I don't think I need any more help on the core part of the
implementation.

Having said that, we are still lacking some UI fine-tuning since the UI
for security, which includes file encryption, has undergone major change
recently in the framework project.  So, some work has to be done to hook
the xls encryption bits to that new framework, which I haven't done yet.
So, help in that area would be great.  I've been talking with Mikhail
Voitenko and Mathias Bauer about the new security framework on the
framework list.

In terms of timeline, 3.2 integration is realistic.  Actually, I already
tried to integrate the CWS for 3.1 (without the UI bits, that is), but
couldn't because of new strings that it introduces (and it was after the
translation deadline).  So, 3.2 probably, unless we hit some unexpected
roadblocks.

So, that's the gist of it.

Best,

Kohei
