Cracking WPA / WPA2 handshakes using GPU on Windows Hashcat is world's fastest password cracker, it is multi-OS (Linux, Windows and OSX), so if you have some nasty problems with proprietary drivers for GPU on Linux or just feel more comfortable inside Windows you can crack Wi-Fi password on it! Best Wpa2 Wordlist; Downloads Wordlists. WPA cracking is a poor example. Without GPU cracking it would take forever to crack, with GPU cracking (pyrit) crunch to generate the numbers (so you dont need a huge password file) you can be. "The single most important aspect of information security is strong passwords. Likewise, the single greatest security failure is weak passwords.”1 Password cracking has always been an exciting topic involving many parties: cryptographer. If you are planning to create a cracking rig for research purposes check out GPU hashcat benchmark table below. We tested hashcat against a lot of GPUs. We found that some old GPU (and cheap) give awesome results, at the cost of more power hungry GPU. In particular, we recommend buying AMD 7950 or R9 280 or better. We found those model very cheap.

Story
Since lot of time I like cryptography and all things aroundcracking/hacking challenge. It is why I have thought about a newchallenge: To crack MD5 as fast as possible using combination of CPUand GPU power (with the help of my GeForce 8800GT and CUDA API).
The development of a MD5 brute force hash cracker using GPU (NvidiaGraphic Processor) is very challenging: Windows 7 professional activation crack key.
- GPU have no easy debug facilities (no breakpoint, no printf.. except on linux), and only possible things is to write test in GPUmemory and afterthe test to transfer the result to CPU memory and check it by hand.
- GPU programming is very different from CPU programming, onGPU all is executed in parallel and algorithm must be adapted.
- GPU hate branch and conditions and that cost lot of time,it is why branch must be avoided.
- GPU memory access requires to be done on128bits or more for best performance and if possible allmemory access shall be avoided.
- GPU shall use as most as possible registers instead ofshared memory.
- Lot of other hints to found specific to each constraint.
Change Log
GPU_md5_crackv0.2.3 changes:- This newversion is a special edition for BackTrack4, thanks to OffensiveSecurity Team for their support and help.
To install GPU md5 Crack on BackTrack 4 do following steps:
1) Download BackTrack 4 latest version and burn it on a DVD and launchit.
2) Launch following commands fromthe shell as root (internet access is required):- apt-get update
- apt-get install gpu-md5-crack
- 3) Now gpu-md5-crackv0.2.3 is ready to use(test it with benchmark):
- ./gpu_md5_crack_0.2.3 -b
- First versioncommand line only, for Linux and Windows.
- Add unifiedoptions and multiple charset selection:
[0-9], [a-z], [a-z0-9], [A-Z], [A-Z0-9], [A-Za-z],[A-Za-z0-9], All Printables. - Add benchmarkoption (-b).
- Add cudadevice choice (-d), to launch multiple instance on different cudadevice for basic multi GPU support.
- Clarifiedrealtime displayed informations.
- Cleanupunused header and source code(cutil is no more used ..).
- Official LGPLv3.0 version see lgpl-3.0.txt.
GPU_md5_crackv0.2 changes:
- Optimized CPUand GPU code to obtain the fastest possible MD5 brute force crackerusing CPU and GPU combination.Thisversion is highly optimized for Geforce 8800GT or more (GPU code hasbeen optimized with best possible assembly code).
MD5 GPU brute force speed exceed 200 millions MD5 hash/second (defaultcharset [a-z,0-9]). (Configuration: GeForce 8800GT and Core2Duo E6750using one core)
Plans for the future
- A new version for 'FPGA' PicoComputing Cards, and maybe anhybrid version CPU/GPU/PICO Card.
- More optimized algorithm to achieve 300 millions MD5 hash /second.
- To support combination of multi GPU using multi threadinstead of launching multiple instance in shell.
- Network-distributed version if enough feedback.
- Windows/Linux version with Qt Cross Platform GUI (insteadof MFC) if enough feedback.
If I have enough feed back/donation I plan also to support othercryptographic algorithm like NTLM, AES-128, SHA-1, RIPEMD-128,RIPEMD160 ..
