NTLM Multihash cracker v0.5

Postby Bitweasil » Tue Jan 20, 2009 5:00 pm

I'm finishing up code on this today and should have 32-bit Linux binaries completed tonight.

Windows binaries will be a bit delayed, as I need to learn how to create CUDA binaries for Windows.

So far, I'm seeing performance around 500M steps per second with 10 hashes on a GTX260.

Performance tuning is still in progress - this will be a beta release, only supporting a single GPU, without any CPU acceleration. I intend to continue improving it, adding performance & multi-GPU support.

I will also be releasing an MD5 version, and possibly some Unix related versions.

This one plays nice with GUIs.

I'm also working on, but don't have fully implemented yet, an auto-tuner, that tests thread & block counts to optimize the card for each run, to achieve maximum performance.

There will also eventually be support for detecting other GPU usage, and backing off appropriately (so you can game with this running, and it will simply get out of the way until you're done).

===== v0.5 for Linux released =====
32/64 bit Linux binaries (with launcher):

Performance is right around 25B hashes per second on a GTX260 with a hash list of 185 hashes.

Specifies the device being used - I have two CUDA capable GPUs in that system.

is the NTLM multihash cracker any different to the Multiforcer speedwise?

Yeah, it's slower. Use the Multiforcer.
