Support of LM ?

[pyr]

Hi,

Could you implement the support of LM hashes ?
A LM hash can be divided in 2 parts, and is only uppercase.. the charset is a bit less than other algorithm.
Do you plan to do it ?
Thanks.

I know of LM

I'm actually looking at grabbing the FRT LM implementation to plug in - there may be faster ways of doing it, but at least for now, doing that would give me LM support. It's on my list, just working on a lot of stuff at once lately

Ignore the glacial rate... this is on an Ion2 Netbook. I get like 38M NTLM/sec on this.

There are also very definitely some optimizations I can make. This is a pure "First pass, get it working" implementation.

... like, "I'm going out drinking with friends now, so I have the big sbox lookup tables in constant memory instead of shared." That sorta silly stuff.

I really need a remote build system... I'll try to push out a beta build soon.

I also need to write a file class that splits the hash into two bits and merges them together - I'm not doing this right now.

But, later this week, it should be ready to rock, and I'll try to push up a new copy of the multiforcer to play with.

Oh, and maybe some LM support love in the rainbow tables...

THERE we go. That's better numbers.

[Rolf]

Great!
Coupled with network distribution, this is big!

I estimate ~400M +-3% for two GTX 480.
Wicked if it comes true!
Cant wait to find out.

Network distribution definitely works. I tested that yesterday.

That sounds about right for a Fermi. Sadly, all of mine are offline right now (power glitch, haven't been home to reboot it yet), or I'd have better numbers.

I'm finishing up the LM hash file class today (automatically handles splitting things up into segments, probably will *not* do automatic case correction for now but I can add that in later in a full SAM dump class).

Hopefully I can actually get a release out this weekend with all the various improvements. I'm hoping to have a more robust workunit class finished by then as well, so network support will actually be solid and not lose a bit of work if clients disconnect.

Right now, I'm only taking LM hashes - not NTLM. I'll add that support later (LM + NTLM, case correction, etc).

For now, my plan is to display the found bits, and if I've found a non-null second bit and not found the first bit, I'll just put lowercase 'x' characters.

Sane?

[Rolf]

Yep!

I estimate ~400M +-3% for two GTX 480.

Bad news.

Your estimate is off by a good bit.

//EDIT: Newer numbers with different thread/block counts (768/360/-m 500)

I've got 328M on a GTX480, and 221M on a stock clocked 470.

*does maths*

A 480, based on performance ratios (which are quite accurate for this stuff), is 1.285x as fast as a 470.

That puts a 480 right around 283M/s (or ~565M/s for two).

In other words, my box can do *ALL* US-charset LM in under 3 hours.

I could kiss you right now!
