Why I need to protect my ebooks against tampering? A good question! Well, I know some people who wouldn't publish anything in any format other than password-restricted PDF format.

I've thought of using digest, but the problem is where to put it? I mean, anyone can open the .epub and remove the hash value. Readers wouldn't notice that since message digest is not part of the standard after all!
