B&N DRM encrypts the eBook using a hash of the credit card number that was used to purchase the book. The plus with the way B&N does it, is that it never needs to check into a central server to make sure you have the right to read your book. The nook has a hash of your credit card on it and just uses that to decrypt the book (a hash, not the actual credit card number).

There is a tool that will do it. There is a 2 step process. You have to enter you credit card number into a piece of software to generate the hash, and then use that hash to decrypt the book. You have to ask yourself if you're willing to enter your credit card number into a piece of software you know nothing about.

If your curious, a Google search of the words Apprentice Alf will tell you all you need to know.
