As far as loading certificate and password from Windows Store is concerned, it is not supported however you can try at your end if it works for you.
Hi Claudio,cduranti:Also, we would like to avoid to store pfx files and related passwords in code / file system (which is a security issue), and use X509 certtificates issued directly from windows store. Is that possible?
We will further look into the details of this requirement and will keep you updated on the
status of a correction.
We apologize for your inconvenience.
just to add that company has also interest in document signing.
The issues you have found earlier (filed as SLIDESJAVA-33889) have been fixed in this update.
