Power of GPU Acceleration: How to Recover PDF, Word, Excel, PPT Password | How To KR

Have you lost your password to open your PDF or Office document? How do I break a password so that the file can be modified without restriction?

Disclaimer: Use this tool to retrieve PDF / Word / Excel / PowerPoint passwords when you have the legal right to view and edit the document, but you have forgotten their password. Do not use them for illegal purposes.

Steps for GPU-Accelerated Password Recovery

A powerful graphics card is good for more than just gaming, it turns out that its parallel processing power is excellent for cracking passwords. Even a low-end NVIDIA or AMD GPU can crack a password 20 to 40 times faster than a CPU alone.

Password Recovery Bundle uses CPU and GPU computing power to deliver the highest performance and is uniquely optimized for all modern AMD and NVIDIA graphics cards. In this tutorial, we'll take you through the steps of using it to retrieve PDF, Word , Excel, PowerPoint password with GPU acceleration.

Download Password Recovery Bundle from its official website to get started. After you download it, double-click the setup file and follow the simple wizard to finish the installation.

When the Password Recovery Bundle opens, click the "Recover From File" button. You'll see a list of options to retrieve documents, archives and passwords from your database. For example, if you want to unprotect an encrypted PDF document, simply select the "PDF Password" option.

When the File Browse dialog is opened, select the PDF file you want to decrypt, and then click Open.

The next window will prompt you to select Recovery for Password: Recover User Password or Remove Owner Password. If you are unable to open / view your PDF file, you should select the first option. When selecting the second option, you will instantly remove the password permissions that protect your PDF from being printed / copied / modified.

When you have chosen to retrieve your PDF password, the program offers three methods of retrieval of passwords: Brute-force attack, Mask attack, and Dictionary attack. Each method has its own advantages and disadvantages.

Brute-Force Attack – Tests all possible character combinations before the proper password is found. The effectiveness of the attack depends on the duration of the password and therefore the combination of numbers , letters and special characters.

Mask Attack – This approach helps you to choose where other styles of characters are likely to look in your password. as an example, if you wish to crack a 6- length password and begin with "qwe," you'll specify the mask as "qwe?

Dictionary Attack – Attempts to guess passwords by using well-known words or phrases as a password. All that's needed is to read line by line from a text file (aka “dictionary”) and take a look at each line as a password candidate.

After you customize the attack settings and click on Next, the program will begin to recover your forgotten password with GPU acceleration. A high-end GPU like NVIDIA GTX 1080 can crack passwords up to 250 times faster compared to a CPU.

The password cracking process won’t stop until your password is found. For testing purposes, we’ve locked a straightforward PDF with the password “qwe803” and Password Recovery Bundle can deliver the lead to under fifteen minutes.
