Remove PDF Password - How to Crack a Protected PDF File

A PDF file can have different contents: an important document, digitized documents, an e-magazine or e-book and so on.

Then how do you get to the content of the file? This is where Passper comes in. "Passper for PDF" is a Windows app with which the PDF password can be removed and the protected file cracked on the PC as well as under the Win partition on the Mac. Similar to the solutions for Word and Excel.

Crack PDF password: these “attacks” work!

In order to be able to remove the PDF password and to remove the protection of the file, the Passper app uses three different approaches that the user can actively choose. The individual processes are called "attacks" and they serve to guess the password as quickly as possible, to use it to unlock the document and of course to display it for reuse. Here are the three options:

• Dictionary attack: Use of user-defined or program-internal lists of possible passwords to try out frequently or repetitively used passwords
• Mask Attack: The user can specify parameters such as the password length in an input mask in order to speed up the search
• Brute-Force Attack: If no parameters are known at all and if it is a character string that does not appear in the dictionary, this attack is recommended

Note: Only remove PDF protection from your own documents

Of course, it is not legal if you remove the PDF password of foreign files and documents to which you are not granted access for good reason. So only use the app on your own recordings for which you have forgotten the password. In case of doubt, you need the consent of the person whose PDFs you should "crack" - for example if you should use Passper for PDF for a friend. I wish you success!
