Re: BarsWF gone opensource

shifted interest as well, but i might look at your code someday, tnx for not having the code get lost on your systems while you shift interest!
i'm a little curious, if you will, what was the complexity and danger you ran into?

and where has your interest shifted to?

fyi: opencrack uncracked list of something like 460k hashes drops to around 113 Mhashes

Re: Distributed crypo-network discussion

hehe, i'll leave such scary code up to you :P (or your intel compiler :P)
hmm... no idea if intel compiler will actually improve speed of my multi hash version... maybe i'll need to go and grab myself a trial version again

Re: Distributed crypo-network discussion

bars, how much cache is on your cpu?
cause i 'only' dropped to like 70-75% with multihash support (125M) on sse2 md5. Of course i started out with a somewhat lower single hash speed (175M), but still :P

p.s. i have 3MB L2 cache.

Re: Simple Questions

windows gives you a warning if you try a password longer then 14 chars, stating it won't be compatible with older versions (like win98).
The result is that it'll store an empty LM hash.

Re: about the algorithm used

i run 32 bit, and i think my cpu has a large cache... so that explains MD4... probably MD5 not going faster with 4 times interlacing because of the larger code then.

Re: about the algorithm used

Side note: I still don't understand how his 32 bit version is so fast interlacing 3 with SSE2 to me seems like it would be slower than interlacing SSE2 and MMX. Well I guess it has to do with cache (for interlacing 3 with SSE2) and/or that SSE2 and MMX have a performance hit such as with switching ...
