------------------------------------------------------------------
Why must the two fields be protected? CreateVisibleSignature.java isn't meant
as part of the library, it is a source code example for people to create their
own signing tool. Some parts may not be useful for all users, e.g. certify.
The only thing that we expose is to allow testing while building and
configuring the test.
