# PDFCrack

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.

### Installation¶

To install PDF Crack,

$sudo apt-get install pdfcrack  ### Usage¶ The general usage of pdfcrack for brute-forcing is, $ pdfcrack -f <file_name>


The genearal usage of pdfcrack when we provided a wordlist is,

$pdfcrack -f <file_name> -w <location_of_wordlist_file>  ### Example¶ Here is an example, using a wordlist. On opening the PDF, we found that the file was protected. We used dictionary attack(using a wordlist) to find the password. In this way cracking the password of PDF files is done when you don't know/forget the password. 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.
