- Author.bikey's are public
- Author.privatebikey's are private
- NameOf.pbo.Author.bisign are public (two versions)

DsCheckSignatures (and probably the MP engine too) does not check filenames. it reads *all* *.bikeys from wherever it can (eg root or ~expansions) and only checks the internal signames at that point. you can rename your bikey PinkElephants.bikey for all it matters.
