In contrast to their CPU counterparts graphics processing units (GPUs) considerably (up to 60 times! ) accelerate the process of Ms Office 2007-2010 password recovery. The difference is stunning. Where's the trick?

In two minds: choosing the right helper.

Actually there is absolutely no magic, and you will see that on a very primitive example.

Think about you are in charge for your kid's wedding party and you need to create hundreds of phone calls inviting relatives and friends. Such an essential mission would be way easier accomplished if you had a couple of co-workers.

The CPU Int. company offers you 4 of the most efficient employees speaking all the languages known to man while the GRAPHICS Ltd. is ready to help you out with 800 staff-members capable of talking one language only. And both companies sell their own services at nearly the same price.

So who you think will be the first to phone this whole lot of people? The guys through GPU Ltd. have to make just one call each although each member of CPU Int. has to make 250 telephone calls. The answer seems quite obvious. But let's not hurry. It's not that easy.

If your kid's beloved and the GPU men share the same language then it's OK and they're likely to win for sure. But what if the newlyweds speak different dialects? This would definitely raise the chances of CPU Int. They are polyglots, you remember?

This is just an example but it is based on actual events.

Modern CPUs have 4 cores. They can procedure data by working at multiple tasks in similar (like make "phone calls" in 4 different 'languages' at a time). Whereas graphics cards have up to eight hundred data flow processors but they only work together at 1 and the same task i. e. "call" 800 individuals speaking one language. It turns out that when you split a job into many homotypic ones graphics cards are outpacing CPUs.

Office 2007/2010 passwords recovery is just the right job to be solved with the GPU acceleration!

Office 2007/2010 security passwords

In its latest editions of Office the Microsoft programmers have modified the file format. Protection algorithms have also been transformed. Without going deep in detail about the increased 128-bit crucial, shift from RC4 to AES or change involving functions from MD5 to SHA1 with increased number of iterations there's one thing we can say for sure: there's been a great collapse in CPU-based password recovery.

For example the leader of the overall performance test Accent OFFICE Password Recovery (Basic Edition) focusing on Intel Centrino Duo 2GHz computes 1 . 700. 000 variants per second for Office 2000 and only 370 (! ) for an Office 2007 document.

Modern Microprocessors are not ready for the amount of homotypic data to be computed when searching for an Office 07/10 password. While graphics cards Will be ready to handle it! The amount of data is more than sufficient so that all of the card's processors may be assigned with a task.

However not every graphics cards can be used by GPU-based password recovery. The must support GPGPU function (general-purpose GPU). The most popular types are NVIDIA CUDA and ATI Stream.

Leading technology

It all began in early 2000s when performance characteristics connected with graphics cards started to grow exponentially. Then came motherboards supporting more than one card in a computer. That enhanced computational functions of an ordinary PC putting it side by side using the first supercomputers. It would be strange to use them just for video games, wouldn't it?

Another important milestone was public release with CUDA by NVIDIA in 2007. The technology ended up being very friendly and perfectly documented. A bit later which same year AMD/ATI - the biggest NVIDIA's competitor -- presented its quite complicated technology ATI Stream. Exactly what followed was like an avalanche.

The new tools and additional documentation were warmly welcomed by developers from all over the world. New software appeared, older one was improved. Execution of graphics cards in complicated calculations, editing videos, exchange quoating or GPU-based password recovery affected efficiency and made it soar which found universal acclaim amongst users.
