PDF Crack is a tool for recovering the pass for Encrypted PDF files. Encrypted files means the metadata of the file was encrypted with some characters.

It has some special features like:

• Checks with the system password and also the user provided password.
• It can crack password by brute-forcing method only for character sets and only when we provide the maximum and minimum length of the password.
• Searches the password from the wordlist.
• Optimized search for owner-password when user-password is known.

sudo apt-get install pdfcrack

Usage

The general usage of pdfcrack for brute-forcing pdfcrack -f <file_name>

If you unfortunately, click ctrl+c then it will save the process until you clicked into an another file called savedstate.sav in the directory where the PDF is present or the current directory.
