PDF Password Unlocker
PDF Password Unlocker is a software application whose purpose is to help you recover PDF passwords using three different modes, namely brute-force attack, brute-force with mask attack and dictionary attack.
Upon a successful password recovery operation, you can open the target document, copy text and graphics, edit the content, as well as print the information.
You are welcomed by a simple layout that allows you to choose between two main tasks, namely recover PDF passwords or look for encrypted files in your computer. There’s support for a help manual in case you want to find out more about the tool’s features.
Scan your system for encrypted files
You can make the application automatically scan your computer for encrypted files. Plus, you are allowed to stop the scan and view details about the process, such as number of scanned items and encrypted files, running time, as well as scan speed.
A list with all the detected encrypted documents is revealed in the main window, along with information about the filename, folder, encryption algorithm, size, date when it last modified, and attack mode that can be applied for recovering the password.
Support for different attack types
PDF Password Unlocker gives you the possibility to recover passwords using three attack types, namely brute-force attack, brute-force with mask attack and dictionary attack. The first one comes in handy in case you do not remember any characters from your password.
The second mode can be used if some of the password characters are known. Plus, you are allowed to specify the password minimum and maximum length, select the character set (lowercase or uppercase letters, numbers, special symbols, and custom characters), and enter the prefix and suffix.
The last approach allows you to apply a user-defined dictionary (which can be uploaded from plain text file format) or built-in one for retrieving the password. You can also shut down the PC at the end of the task.
All in all, PDF Password Unlocker provides several handy features for helping you recover PDF passwords. On the downside, it eats up CPU and memory so your computer’s performance may be hampered.
