What no one seems to have mentioned here is that they can be run in parallel. Sure for the price of ~10 days of processing you could buy a card that is good for years, but if you need it urgently, amazon may have an advantage.

If you break the task down, you can run that entire 10 days worth of processing on a couple of hundred instances and have it finished in an hour. You can't achieve the same kind of flexibility with physical machine.

Long term physical hardware is the better investment, but if you have extremely bursty requirements, letting someone else deal with the machines might be the better option.

Worked on a fun project and thought this may help someone else out who's looking for some serious hardware to crack on. Theres a couple of other guides out there but they are pretty out dated and some of the AMIs dont even work any more.

Thanks for your post.
But my problem is that my hacking speed is too slow.

hashcat (v4.1.0) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

Is there any difference between cudaHashcat and Hashcat (v4,.1.0)?

Please don't necro/hijack old threads.

And there are a lot of differences. The biggest being that cuda is no longer being used by hashcat as we have standardized OpenCL.
The best thing you could do is to read through the change logs from the time hashcat went from cuda/ocl to current.

Also, I noticed you are comparing sha512 to sha512crypt, which are two different algorithms.
