CUDA Multiforcer 0.7 Source

[xdunk]

i have a huge md5 hashlist (about 1,000,000+) to crack with ver 0.7. so i tried it, then give me this Msg : "MAX LEVELS REACHED. EXITING. "
then i searched the source code and find this msg at line 32 in Multiforcer-common.c:
"define MAX_LEVELS 100000"
is this means the max hashlist limits is 100,000?
so how to take this limit away? thx!

Your list is sorted.

Randomize it.

sort -k 1.2 filename

^ will do it - that sorts by the second character, letting Quicksort do it's thing. It performs really badly on already sorted lists - I need to add a check for this.

ok! it's working now!
thx!

on my GTX 285:

Done: 99.99% Step rate: 69.0M/s Search rate: 73119368.1M/sec

that's a great job!

Ah... you have a GT200 core.

I'm guessing you can go faster if you don't mind a badly lagged UI.

Try passing:

--threads 512 --blocks 512 -m 500

That should up the speed a bit, if you're not using that already.

You can also *try* passing -l in - that uses a 512MB bitmap in global memory, which is slow, but on large hash lists may be faster than the search of the hash list it's doing. Try it & see.

i'v done this already...
the speed above is the "top" speed now~

and one opinion i want to give you: like JTR' john.pot file, save the result done before in it, Not load cracked password again and again~ that's will be a lot easy to manage Huge hashlist

thx ur great job again~

Hi Beatweasil! I'm loving the work you're doing with Multiforcer, but I've a question: will you add support to other hash algorithms (oracle, sha-1, etc...) ? Thanks

[xdunk]

ok
i'wrong...

After i update the video card driver to 6.14.11.8608 then the result is so diffirent:

11.1% Step rate: 472.1M/s Search rate: 500254678.7M/sec

that's amazing...

[Bitweasil]

Hrm. That... doesn't seem right, but I've not tried the new drivers. Is it finding stuff at that search rate? I didn't think it would run that fast with 1M+ entries... it shouldn't?

and the 1-6 lowernumeric options give me about 60,000 MD5 hash results

so, this speed is really amazing...

[Bitweasil]

Alright... I'll have to play with the new drivers. I really don't understand how my code should be running that fast on 1M hashes - the new cards aren't *that* much faster.

What's your single hash rate?
