Crack RAR Password with PassFab for RAR

It’s 2021 and the topic is not new. We have already covered a detailed guide on RAR password recovery before but today we are introducing another great software for cracking RAR passwords – PassFab for RAR.

Before we jump on to the how-to part, I want to make it clear that this is going to be a time-consuming process and there is no way to bypass RAR passwords like claimed in some articles online.

How to recover RAR password with PassFab for RAR?

Before you get started, try to get as many details as possible about the password. This will help us in later steps.

1. Download & Install

Download PassFab for RAR from the link below and install it. Optionally, if you have purchased a license, activate it.

You can use their trial version for dictionary based attacks but it will only retrieve the first few characters of the password.

2. Import the RAR file

Click Add, navigate to the folder which contains the RAR, and select the RAR.

3. Select Attack Type

This is the most important step when it comes to a fast successful recovery.

Dictionary Attack

If you are sure that your password is one among a set of supplied words, you can use the Dictionary method. PassFab provides a large dictionary file with commonly used English passwords. But you can also download dictionary files from the web and supply them to PassFab using the settings button next to Dictionary Attack.

For example, the following two links provide two such dictionary files which you can download and load into PassFab for RAR.

Brute Force with Mask Attack

Use Brute Force with Mask Attack option when you know parts of the password such as what it starts/ ends with, the password length range, etc.

Supplying as much information about the password can bring down the recovery time exponentially!

To give you some perspective, let us consider our password is 7 characters in length and consists of smaller case alphabets and numbers. This makes a total of 1,028,071,702,528 possible passwords, takes roughly 11 days to crack with 1M pass/sec speed. Now if we knew just one character in the password and its location, it brings the search set down to 19,770,609,664 and it takes just 5.5 hrs to crack with 1M pass/sec!!

Brute Force Attack

If you know nothing about the password then go for the Brute Force Attack but bear in mind that it is a painfully slow process.

4. Start & Wait

The next step is to click the Start button and wait! This could take hours or days to complete. But the good thing about PassFab for RAR is that you can stop the search and resume it later; how convenient!

I was able to get an average speed of 9k Passwords/ sec with my i5 8400 processor and GTX 970 graphics card.

Congratulations if you find the password! And if not, you can rerun the recovery with different settings 🤞.
