PassFab for PDF

PassFab for PDF is a lightweight but powerful password-elimination application that may enable PC users to unlock PDF passwords and gain access to files with a single click of a button and a little patience. With full support for all sorts of PDF files and a wide range of password detection processes, users who have locked PDF files can finally breathe a sigh of relief when they discover a solution to unlock documents for which they have lost or forgotten their password. These credentials can be used not just to access files, but also to enable services such as PDF editing, copying, printing, and more. PassFab for PDF allows anyone with a modern PC to maximize the potential of their PDF files.

However, even with current PCs, determining a reliable password is a difficult operation because the app must manually examine hundreds of millions of combinations of characters, symbols, and numbers that may be used in a competent lengthy password. To shorten the time required to crack a password, PassFab for PDF uses three different attack patterns - "Dictionary Attack" which will use terms and possible words from a large inbuilt or customized dictionary, "Brute Force with Mask Attack" where users can customize the length of the passwords, symbols, and numbers that they know were once part of the password, and "Brute Force Attack" that will try all possible combinations, which will naturally require more time than 

To speed up password generation and testing, the program features GPU acceleration, which can perform up to 40 times faster than traditional CPU processing. Both Nvidia and AMD graphics cards are supported, and users may use the built-in stop and auto-resume recovery procedure to free up their PC for other work as needed. 

The entire process of getting PassFab for PDF up and running on a modern desktop or laptop PC is simple: simply select the PDF file to unlock and then choose one of the three encryption-breaking methods available. The software will provide real-time information on total time spent, search speed, and the number of passwords examined, which can reach several million in only a few seconds. 
 

PassFab for PDF can be tested for free during the initial trial time, but the app's full functionality is only available in the paid edition. Users are encouraged to supply the app with a multi-core CPU or a powerful GPU for faster password recovery. 

Please keep in mind that purchasing the application grants you access to all of the features it offers.
