Locking your PDF document behind a password is one of the best ways of keeping your information private and secure. Yet, sometimes forgetting or losing the password is unavoidable, thus locking yourself out of your own data. If that happens, the wise thing to do is to look after a software capable of recovering the credentials. You need an app like Any PDF Password Recovery, a straightforward app that can help you re-access your PDF documents.

From the moment you load the PDF in, to the final scanning process, there's just one thing to do, and that is choosing and configuring the attack modes. These cryptanalytic attacks influence the way your password will be cracked, so read their short description found between parentheses carefully.

The first method is also the one that needs a small disclaimer regarding the processing times. Why? Because the Brute-force Attack will try all possible combinations in order to find your password, which means that the waiting times will vary, from mere minutes to hours, or even days. One important aspect of this cracking method is that it comes in handy when you have no idea about the actual password. If you've partially forgotten or have a huge list of combinations and you don't know which goes where the other two attack modes can do a quicker job.

Brute-force Attack with mask attack might sound similar to the first approach, but it's way more effective. How so? Well, if you remember even the tiniest bit of a password, you can use that to customize the search and pin-point the combination way faster.

Regarding the third and last mode — Dictionary Attack — this one will only work if you upload a list of combinations and let the app snoop through it in order to find the right credentials and match them.

If your PDFs are locked behind passwords you no longer remember, Any PDF Password Recovery can pitch in and help. With an intuitive operation and well-explained attack modes, this app can quickly grow on you, especially if you are dealing with tons of locked PDFs daily.
