Hi everybody, I'm new to this forum and I need a little help: I've found on the internet some PDFs but they are encrypted and I can't decrypt them. Who can help me?

PS. Sorry for my bad English uploads/2756/pdf-6534104-1.pdf - pdf-6534104-1.pdf

This is not a PDF document. It is a file with binary data.

At the end of the file is the data structure of PDF files visible. The begin of the file is damaged by binary data.

I don't think so.

The file come from an application for read scholastic books, I want to read this book without the application because it is very slow and uncomfortable. each page has its own file.
Do you think is possible to do what I want?
