Yeah, working with generated passwords on GPU is kinda slow cause it is very costy to transfer every generated password to GPU, as well as generate it on GPU.
Probably it might be limited to CPU-only attack, which should not be that terrible as number of variants here is much smaller.
I would be happy to run BarsWF at half its maximum speed if I could specify the charset for each character space or run dictionary or hybrid searches, it would still be many times faster than the other programs I have been using. 8-)
EDIT Also need the ability to input a list of hashes..
Is it done yet..? :D

I dont know how thie pgu cracking works but cant you do like this:

If you say that the last char is a lowercase cand you let the GPU run only lowercase variants
and then let the CPU take the rest variations?

Having different charsets for different positions is possible for both CPU & GPU

Yes, it is slow to generate every single password on the CPU and then transfer to GPU for checking.
But as long as we can generate passwords efficiently right on GPU we are good. Initially I was thinking that having different charset for different positions would be hard, but that is not correct :-)

So it can go even faster then we first thought? Like super fast? Like Roadrunner fast? :shock: :o

This would be great if you where cracking a database where you know ppl have to use atleast one of each.

Like "your password has to include uppecase, lowercase and numeric"


And on some pages you have to start or end with a special char

-first_is "0aA~" (first char is a numeric, lower, upper, special)
-last_is "0aA~" (last char is a numeric, lower, upper, special)
-first_not "0aA~" (first char is NOT a numeric, lower, upper, special)
-last_not "0aA~" (last char is NOT a numeric, lower, upper, special)
what about those suggestions bars?

They sound very good:D esp. the last

This might be helpful for example if your CPU cooling is poor and you computer crashes after a few minutes if you stress your CPU too much (I had this some weeks ago, but next week the problem should be gone as my new cooling equipment should finally arrive :) ).

Yes, I could lower the priority, but I want the program to ignore the CPU (as much as possiple) so I can use me CPU for anything else and to prevent it form being under stress for long periods of time. And of course to save power because cpu is less efficient.

Control over CPU & GPU usage is coming. It would be possible to use ~0% of CPU :crazy:

I personaly prefere the "multi hash support (attack a large list of hashes)" on highest priority , i hate those batchfiles ;_)

Hi

could you add IPB2.x format :

example (user:hash:salt)

user:cadf629230518b599744160f4637c6b9:Q[B0F
user2:864bde004528c2b56ffaec8848f90d76:]NsP]
user3:ab491f13105f34f6ac64fa0d7ab252f6:Xs_&w

thanks ! :joy: :joy: :joy:

Thank you so much for your work on BarsWF. very much so looking forward to the mscache version.
couple considerations that may or may not have been discussed, but i think all can be really valuable features for BarsWF.

1. wordlist functionality. Alot of GPU cracking tools are brute force centric but i think there is a huge amount of benefit to add wordlist functionality.
1a. allowing the tool to accept wordlist input from stdin is even better.
2. linux support. obviously this is in the works, but i wanted to give it some more support
3. pyrit-type design model, pyrit is a linux based tool used for gpu cracking wpa-psk's has a really excellent design model. Basically the author wrote the cpyrit python class which handles the hash computation on the gpu/cpu, then everything else is separate in a python app. This makes it really really easy for people who want more functionality of the app to do it themselves. For instance, i needed it to support wordlists a little differently and accept words via stdin, so i just wrote a quick python app using cpyrit, and bam! everything was done. This is definitely more of a long term thing, but if more applications were written in this way it would make changing tools for specific projects so much easier. Nonetheless if barswf ever wanted to take that direction, it would be awesome!

thanks again for all of your hard work!

The problem with wordlists & stdin is bandwidth.
1 card at 1bil hashes/second need like 10Gb/sec of data, so any external password generation or wordlist source would slow down everything by a factor 10-100.
Personally, I still think that pure wordlist attack is efficient for CPU kernel, but not GPU one.
It might be efficient on GPU for wordlist "modificators"

wordlist mutations are VERY powerful... so i think it is a valuable item for the wishlist :)

I want a wordlist support too. A modificatior would be fine too. Or a pattern crack.

Like

+aHJZ+4X&*

where + means 1 char * means x chars.

A modifactor like

password
1111password
password1111
9999password9999
would be fine too
