BarsWF is basically an MD5 cracking tool and at the moment, is currently the fastest. Right now on nVidia 9600GT/C2D 3Ghz CUDA version does 350 M keys/sec, SSE2 version does 108 M keys/sec. You may check benchmarks of all known good MD5 bruteforcers here.

Changes in 0.8

* Added checks for errors when calling CUDA kernel.
* Now you can specify custom characters for charset using -X switch.
* You may specify minimal password length using -min_len.
* Save/restore feature added. State is being stored to barswf.save every 5 minutes or on exit. You may continue computation using -r switch. You may manually edit .save file to distribute job on several computers (but this is up to you - it is quite simple and non-documented ). BarsWF will also write found password into barswf.save at the end.
* Improved speed for cards GTX260, GTX280, 8800GT, 9600GSO, 8800GS, 8800GTS - by approximately 10%, all other cards will get just 1-2%.

System Requirements

* CUDA version only:nVidia GeForce 8xxx and up, at least 256mb of video memory.
* LATEST nVidia-driver with CUDA support.Standard drivers might be a bit older (as CUDA 2.0 is still beta)
* CPU with SSE2 support (P4, Core2Duo, Athlon64, Sempron64, Phenom).
* Recommended 64-bit OS (WinXP 64 or Vista64). 32-bit version is also available.

SHA-1 Cracked

Posted by Bijay | 5:33 AM | , | 0 comments »

A paper about cracking SHA-1 originally surfaced in 2005, from a fairly reputable scientific source in China, it was widely publicised nor talked about much.

But then recently, just last month China managed to make a wave out of it, almost 2 years after the initial ‘report’.

It was even Slashdotted on January 20th 2007, the article states the following:

These two main algorithms are currently the crucial technology that electronic signatures and many other password securities use throughout the international community. They are widely used in banking, securities, and e-commerce. SHA-1 has been recognized as the cornerstone for modern Internet security. According to the article, in the early stages of Wang’s research, there were other data encryption researchers who tried to crack it. However, none of them succeeded. This is why in 15 years Hash research had become the domain of hopeless research in many scientists’ minds.
