When Password Recovery Bundle opens up, click the “Recover From File” button. You’ll see a list of options for recovering your documents, archives and database passwords. For example, if you want to unprotect an encrypted PDF document, just select the “PDF Password” option.
When the File Browse dialog opens, select the PDF file that you want to decrypt and then click Open.

When you’ve chosen to recover PDF user password, the program offers 3 password recovery methods: Brute-force attack, Mask attack, and Dictionary attack. Each method has its advantages and disadvantages.
- Brute-force Attack – Checks all possible characters combinations until the correct password is found. The success of the attack depends on password length and the combination of characters, letters, and special characters.
- Mask Attack – This method allows you to determine where certain types of characters are likely to appear in a password. For example, if you want to crack a password of the length 6 and the password begins with “qwe”, you can specify the mask as “qwe???“
- Dictionary Attack – Attempts to guess passwords by using well-known words or phrases as a password. All that is needed is to read line by line from a text file (aka “dictionary”) and try each line as a password candidate.Tip – Read Using Common Phrases Makes Your Passphrase Password Useless
