Well, I guess that depends. What is the point of the second level of encryption? Yes a 4 digit key is not likely to be very secure, but lets say you are living in an oppressive third world country and are afraid the government will hack into your computer and arrest you for the books you are reading. There are plenty of file encryption programs out there that provide fairly strong encryption. No ebook readers support them, so you would have to manually decrypt before use, but while encrypted, only you would be able to get access to them...
