Unfortunately in Windows store 8.1 there is no API available to extract or create a archive with password ,at least this what i find out after a lot of recherche on the web,
And because this is very important for us to find out something, we created a package on nuget.org that works like magic. Basically we manage to create/extract archive with password but sadly this does not pass the certification Kit evaluation.

I wonder if anyone can help us to get this API pass the test.
this is what i get in the certification Kit evaluation
