Encryption of ebooks in Calibre
This is inspired from the discussion about watermarking in the Harry Potter thread.
I have bought some ebooks that are secured by watermarking, a very commendable method.
But if my Calibre database should fall in the wrong hands, and the books in question be found on the darknet, then I could be in serious trouble. It would therefore be nice if you could encrypt selected books in Calibre and automatically decrypt the books when they are uploaded to your device.
I know there is third party software that can be of assistance and I would also like suggestions in that direction.
