Part 1. Two kinds of PDF password

Before starting to remove PDF security without password, we should know there are two kinds of PDF password:

a. user password (or called open password). People always set this kind of password to protect their PDF files from being opened by others, unless the PDF file's owner tell you the correct user password, you can't open or view the user-password-protect PDF files;

b. owner password. This one is used to put restrictions of copying, editing or printing. Most PDF files we meet are with owner password and we need to remove PDF restrictions when we want to print a PDF file with owner password.
