Re: BarsWF and (MD5($password)+$salt)?

BarsWF can't do this yet (and probably won't due to stopping in dev.) - It doesn't do salted passwords. Refer to some of the other crackers available.. But if your pc is fast enough (not likely), you can hope to reveal the hashed password in conjunction with the salt, and then crack the hashed pass...

Re: Would this system be brute-force-uncrackable?

Are you talking about this? http://en.wikipedia.org/wiki/SecurID And no it is not uncrackable. Well something that has a 256 bit key I'd say is uncrackable (well depending on the algorithm such as a 256 bit RSA private key is crackable in like a hour on a new computer). haha, yes thats what i was g...

Re: ATI or Nvidia???

OpenCL changes the dev environment a bit. However, atom of oclhashcat claims the nVidia OpenCL runtime is massively buggy. What type of work are you doing? For crypto, ATI is often faster because it has a hardware barrel rotator. For other stuff, it just depends. Well im about to start an MSc in So...

Re: ATI or Nvidia???

I believe ATI gives the better performance measured in FLOPS, but I'm sure nVidia have the better development utilities. CUDA is simply better documented than Brook (which isn't supported anymore). However, depending on how the work with ATI's new project goes, ATI might even be better in developmen...

Re: Saving the keys/hashes?

You want a LHT (Lossy Hash Table) but these can only be made with key spaces of at most a few trillion. 4.8 trillion is the largest and that's on 50 TB. It can be done with 16 TB and each lookup cost 2 hard drive seeks and about 160,000 MD5s. Add or subtract 600 GB each time you double or half the ...

Re: ATI SDK Stream 2.1 : some improvements ?

The brook versions are AFAIK not supported anymore. Brook was apparently a failed ATI project to counter CUDA, and it will stay that way - ATI has it's eyes on a new language of theirs, OpenCL. This means you probably won't get much help on this front.
