For whatever reason, Kobo does not encrypt the ePub3 navigation document, the ePub2 NCX document or the CSS stylesheet(s).

I don't have a Kobo device, so no serial number. I download them to my PC for reading.

Well, that doesn't actually work, since i've already gone through and added metadata (incl. cover) to these books.

I see. I'm getting curious about how to write plug-ins for calibre. Seems useful in this type of situation.
Thank you!
