We all know we can use aircrack-ng to run a wordlist attack to crack WPA/WPA2, in this article I’m going to show you how to do the same using a tool called HashCat, and compare its speed with aircrack-ng.
The advantage of using HashCat is unlike aircrack-ng which uses the CPU to crack the key, HashCat uses the GPU, this makes the cracking process MUCH faster (results below).
Installing & using Hashcat
Wi-Fi Security: Cracking WPA With CPUs, GPUs, And The Cloud. By Andrew Ku. Pyrit Benchmark, 3949.13 PMKs/s, 17 771.6 PMKs/s.
- First you need to download Hashcat from https://hashcat.net/hashcat/
- Navigate to the location where you downloaded it, and unzip it, personally I like to use 7zip.
- Open the Command Prompt (go to windows search and type cmd).
- Navigate to your Hashcat folder where it’s unzipped.
- Type hashcat32.exe or hashcat64.exe depending on the architecture of your CPU.
- In order to use the GPU, you need to get its id using the following command
mine is #3. Then you need to use the hash type which is 2500 for WPA, I do recommend using
to get familiar with the tool.

To specify device use the -d argument and the number of your GPU.
The command should look like this in end
Example:
Where Handshake.hccapx is my handshake file, and eithdigit.txt is my wordlist, you need to convert cap file to hccapx using https://hashcat.net/cap2hccapx/
Results:
Test1: Using HashCat, with Asus GTX 1080 OC edition which has GPU Boost Clock with 1936 MHz, total GB ram of 8 Gigabytes, and Cuda cores 2560.
CUDA = Computing performance Boost Clock = Increases the Clock speed.

Hashcat took 4 mins, 45secs to reach the end of the wordlist and crack the handshake with a wordlist of 100,000,000 passwords.
Test 2:Using Aircrack-ng on Kali installed as main operating system with is i7-7700k CPU – base clock of 4.20, turbo clock 4.50Ghz with 4 cores and 8 threads, it would take 4 hours 22 minutes 14 seconds try all the passwords in the wordlist.
Test 3: Kali installed as a virtual machine, in this case it would take 11 hours, 31 minutes and 40 seconds to try all passwords in the wordlist!

During the last few years, progress on the CPU performance front has seemingly stopped. Granted, last-generation CPUs are cool, silent and power-efficient. Anecdotal evidence: my new laptop, a brand new MacBook, is about as fast as the Dell ultrabook it replaced. The problem? I bought the Dell laptop some five years ago. The Dell was thicker and noisier, its battery never lasted longer than a few hours, but it was about as fast as the new MacBook.

Computer games have evolved a lot during the last years. Demanding faster and faster video cards, today’s games are relatively lax on CPU requirements. Manufacturers followed the trend, continuing the performance race. GPUs have picked up where CPUs have left.
Nvidia recently released their new GeForce GTX 1080 graphics card based on the new Pascal architecture. Elcomsoft Distributed Password Recovery 3.20 added support for the new architecture. What does it mean for us?
GPU Acceleration: The Present and Future of Computer Forensics
Today’s desktop video cards pack significantly more grunt compared to contemporary desktop CPUs. The powerful GPU units can deliver unmatched performance in massively parallel computations, offering 100 to 200 times greater performance compared to CPUs. All this performance is still relatively useless when it comes to regular computing.
The several hundred individual GPU cores are built specifically for “one code, different data” scenarios, while general-use CPUs can run different code on each kernel. Since breaking passwords involves executing the same code repeatedly, just with different data (encryption keys or passwords), a large array of GPU units makes lots of sense.
How does it scale to real-world applications? A low-end Nvidia or AMD board will deliver 20 to 40 times the performance of the most powerful Intel CPU. A high-end accelerator such as the Nvidia GTX 1080 can crack passwords up to 250 times faster compared to a CPU alone.
Just how important is GPU acceleration, exactly? As an example, a common 6-character password (lower-case letters with numbers) has just about 2 billion combinations. If that password protects a Microsoft Office 2013 document, you’ll spend 2.2 years trying all possible combinations. Using the same computer, add a single GTX 1080 card, and the same password will be cracked in under 83 hours. That’s 3.5 days vs. 2.2 years!
Nvidia Pascal Architecture
Nvidia’s latest GPU architecture gives a significant performance boost compared to Nvidia’s previous flagship. With 21 half-precision teraflops, GTX 1080 boards are 1.5 to 2 times faster breaking passwords compared to GTX 980 units.
According to ElcomSoft’s internal benchmarks, Elcomsoft Distributed Password Recovery can try 7,100 passwords per second for Office 2013 documents using a single Nvidia GTX 1080 board compared to 3,800 passwords per second on an Nvidia GTX 980. When recovering RAR 5 passwords, using a single GTX 1080 results in 25,000 passwords per second compared to 13,000 passwords per second on a GTX 980.
Cannot see the numbers for CPU-based benchmarks without a magnifying glass? In case you wonder, we were only able to try 30 (yes, thirty) MS Office 2013 passwords per second on an Intel Xeon E5 2603 without GPU acceleration. Compare that to 7,100 passwords per second using a single Nvidia GTX 1080 board!
Nvidia Pascal is a major break-through in GPU computations. If you need a reliable powerhouse to break passwords faster, consider adding a GTX 1080 board to your workstation.
What if your computer already has a GTX 980 installed? If you have a free PCIe slot and sufficient cooling, and if your computer’s power supply can deliver enough juice for an extra GTX 1080 board, then you can just add the new board without removing the old one. Elcomsoft Distributed Password Recovery will use both GPUs together for even faster attacks.
Does it make sense keeping a GTX 980 along with the new GTX 1080? By keeping the old card together with the new GTX 1080, you’ll get an additional performance boost of about 20 to 30 percent. Whether this extra performance is worth the increased power consumption and excess heat is debatable, but if your power supply and cooling can reliably manage both cards working at their maximum performance, by all means go for it!
