PDF Security Hacks

When documents need to be limited in access, it’s about time to convert that file into a PDF document. Just like what professionals say, a good document format is one that can be universal and can answer to the needs of the user. PDF files prove that point.

PDFs are also best used for files that need limited access and need layout retention. Unlike Word documents that easily gets edited on a single touch of a keyboard, PDF documents stay within its layout and remain non-editable when viewed. Editing PDFs is also possible and can even have a password if you need it to.

Converting is easy with a powerful PDF software but locking and unlocking one is very tricky. Encryption can be in different interpretations and there are different hacks for each one. Let’s tackle five different situations that tackle PDF security:

Remove security

PDF unlock tools can be misunderstood as a hack that makes an encrypted PDF file magically unlocked. What it actually does is to strip the document of its security after you’ve confirmed your rights on the document by encoding its password so that the next user can open it without the need for one.

Unlock hack with Google drive

From our past article, we have tackled how to hack, open and unlock a secret PDF file that has a password. This time, unlocking doesn’t just mean removing the password permanently, it also means opening a document without one and recreating the PDF as a new file. This was easily done by opening the file in Google drive and saving it as another PDF.

The problem with this method though is that it doesn’t always follow the layout that was originally made but at least you can open it.

Add restrictions

Open passwords are those passwords that let people open a PDF document. An uncommon feature that can be added on these files is to add an Owner’s password, which allows users to add limitations and restrictions on a PDF document. You can limit people who print, copy, modify, print in high resolutions, fill a form or sign the document just by adding this password. The owner’s password may look as if the document is available to everyone since it can be opened easily but once the reader tries to do anything other than viewing it, this is where the password becomes required.
