Step by Step Guide to Crack PDF Passwords

PDFs are a common format for document files and almost everyone uses pdf files for their work or study. When the use of a pdf file has been restricted, be it an opening restriction or an editing restriction, it becomes a nuisance for someone who does not know the restricting password.

Some users often password-protect their important documents for privacy concerns. And there are situations where one comes across such a document or pdf file and is unable to utilise the file’s contents because, either they have forgotten the password or they do not know it at all. This may be a huge hindrance for someone in performing their tasks and duties.

Whatever the case might be, no need to be dismayed as there are ways that can be used to unprotect a pdf document.

Cracking the Opening-Password

Some pdf files have an opening restriction, meaning they cannot be opened without a password. The “Recover Passwords” option in Passper for PDF helps in this regard. It cracks the file’s password and presents it to the user. To utilize this functionality, follow the following steps.

Step 1: Click on the “Recover Passwords” option from the main menu.

Step 3: Passper offers a number of methods for password cracking. The efficiency of these methods depends on the type of password the file has. If you have partial knowledge or a good guess what the password might be, then it is better to use one of the first three options i.e. Combination Attack, Dictionary Attack or Mask Attack. If your guess or partial knowledge is correct, then these methods would be the fastest. If you have no idea what the password might be, then it is advised that you go with Brute Force Attack. This method tries all possible combinations and takes a longer time.

Now, select your preferred recovery method. By doing so, the grey-coloured “Recovery” button at the bottom right corner will turn red and active.
