Multiple hashes

Post by Stavros » Mon Mar 23, 2009 7:27 pm

Hello,
are there any plans for multiple hashes? It could speed up the decryption process considerably...

Yes, it is in implementation right now.

Not quite as fast as BarsWF, but they're cross-platform multi-hash CUDA brute forcers.

Also the InsidePro stuff is very fast on multiple hashes, but not free.

Thanks for the link, I got Multiforcer but it's quite a bit slower... My interest is academic at this point, so I'll just wait for the new version of BarsWF!

If you're dealing with multiple hashes, it will be substantially slower than working on a single hash. There's a much faster version I have that I just need to finish tweaking & release.

I noticed that, for 100 hashes it runs at 200M/s per iteration and for 1000 it runs at 18M/s per iteration. I wonder why that is...

Because it has to test each generated hash against the hash list, and version 0.61 is fairly inefficient at doing so. The version currently in development, 0.7, is much faster at dealing with hash lists.

What OS are you running? I could possibly get you a beta if it's Linux. I haven't tested the new version on Windows yet, and there's still a bit to finish on it before packaging for release.

I'm running Linux pass it to me, but only if you want.
I've got an Intel Q9555 and a GF GTX260 if it matters.
But Stavros has to give me his MD5 hashes first, because I have no MD5 file to test your script. ;)
Then I could crack Stavros' hashes and you will become some beta-feedback. :wink:

Oh, if you want to PM me the hashes, I could run them easily enough. I'm hoping to finish coding on it soon, I've just been busy with paying the bills lately. :(

Oh, I have no hashes, I just generated a bunch of test ones to test out the various programs... I'm sure you know quite well how to generate your own, but I would be happy to help you betatest the Windows port once it's stableish (not crashing my system, that is :P).

Use LHC for now it's free and fast, but it only works in Windows.
