How to get back the open password on your PDF file

PDF format is a popular format for file sharing. PDF files keep the format of the text unaltered when you transfer them across platforms. To make your textual information safer, it is important to set an open password on your PDF. Thus, unauthenticated people are asked for the correct password when they try to view the file content of your PDF. But there are times when you lose the password. A long or complicated password combination causes you to forget the password. Adding different passwords on multiple PDFs makes you mix up the passwords. The notebook you wrote down the password somehow is gone. The PDF encryption brings you big trouble once your open password is lost. You may ask yourself: "How to recover my PDF password?" Please continue reading this article. In this article, we will be looking at two methods to recover lost PDF passwords.

If you are less experienced with such a software program, let me explain each attack mode for you.

As long as the password is included in the dictionary, it will be found very fast. It is possible to build your own dictionary and attach it to the software. After you buy the product, you will receive a full dictionary of 3GB.

Mask Attack: Mask attack is the attack mode you should make good use of if you can recall some parts of your password. You can provide some information about the password including the length and the character types. The program searches your password according to your instructions, so the speed of password recovery will be dramatically enhanced. Tests indicate a four characters password is found within a few seconds to several minutes under the mask attack mode.

Brute Attack: The brute attack mode comes to your aid when you don't remember anything about the password. It tries all possible password combinations until it reaches the final result.
