Epub source code issue during extraction
题
I'm trying to 'see' the source code for an interactive ebook (.epub) that I have on my ipad and it is running fine on Ibooks app.
What I did is changing the ebook's file extention .epub to .zip and unzipping it. The problem is that whenever i try to open the files inside the epub folder they are completely messed up:
where is the problem? (The book I tested with is on itunes store "the wind and the sun")
解决方案
The book is encrypted using Apple's FairPlay DRM.
