PDFCrack is a powerful tool designed to decrypt password-protected PDF files. Follow these steps to use PDFCrack effectively:

Step 1: Installation:

Ensure PDFCrack is installed on your Linux or Unix-based system. You can install it via the package manager or download it from the official website.

apt install pdfcrack

Step 2: Open Terminal:

Open a terminal and navigate to the folder where the encrypted PDF file is located.

Step 3: Launch Attack:

Enter the following command to initiate the attack:

pdfcrack -f filename.pdf

Replace "filename.pdf" with the name of the encrypted PDF file you want to crack.

Step 4: Customization (Optional):

You can customize the attack by using additional options. For example, to set a specific character set, use -c. To define a minimum password length, use -m. To set a maximum password length, use -M. To skip passwords below a certain length, use -n.

Example:

Let's say we have a file named "encrypted_file.pdf" with an unknown password. To crack it using PDFCrack with a minimum password length of 6 characters and using only numeric characters, enter the following command:

pdfcrack -f encrypted_file.pdf -c 0123456789 -m 6

Important Note:

Use PDFCrack responsibly and only on files you have the rightful permission to access. Unauthorized cracking of passwords is illegal and unethical. Always seek consent before attempting to crack a password-protected PDF.
