Problems with PDF passwords

If you can neither copy, edit nor print text of a PDF document due to file restrictions…

Or, if you can’t type the password in the PDF password box because it seems to have slipped your mind…

Then you definitely need this program. Accent PDF Password Recovery successfully solves problems with lost passwords of any PDF file.

Password recovery with Accent PDF Password Recovery

Security settings of Adobe PDF offer two types of passwords:

  • Permissions password (also known as a Master password) limits access to a document by restricting certain features but you can still open and view it
  • A Document Open password (also known as a User password) blocks access to data completely and requires a user to type a password to open the PDF.

Accent PDF Password Recovery handles both types of protection, but the methods to remove each type of password are different.

The program can instantly remove a Permissions password, that is immediately after opening a PDF file in the program. The program will create a decrypted copy of the original document without password protection. That works out for all versions of PDF format.

However, it is impossible to instantly find or remove a Document Open password. You can only recover it, that is find it through a brute force attack. AccentPPR employs maximum CPU power of any PC and guarantees brute forcing at full speed.

As soon as you run a file in the program, you will see description of the enabled security options. The program will then offer you to choose a password attack – a method of generating passwords to be tested:

Accent PDF Password Recovery offers three types of password attacks:

  • brute force attack – systematic checking of all possible passwords and passphrases from a given range
  • brute force attack with extended mask – a method that consists in generating and checking data values individually for each position in a password (see examples)
  • dictionary attack – a form of brute force attack that consists in running through a set of dictionaries by trying each entry and modifying it on-the-fly (up to 4 dictionaries can be linked up simultaneously)

Select an attack, make the necessary settings and run the search. Accent PDF Password Recovery will check all values from the specified range, and when it finds the “Document open password”, you will see it on screen:

Read more about Accent PDF Password Recovery settings and password attacks, as well as tweaks and tricks in the help file and in the "Practice" section of our Knowledge Base.

NB: You can only expect successful recovery of a “Document open password” if this password is in the specified range of values. If the password has not been found or brute force attack is taking too much time, then try customizing your range, select a different attack or change the settings.
