RAR password recovery on GPU

it works on "red" and "green" GPUs... it looks like convenient real-world benchmark to

how much faster is it than using a CPU? or is that version not available?

[ajaidev]

I would say this is a very very useful GPUCPU app out there. I have a dozen or so winzip's and rar files with passwords i cant recall, now with this app i can finally unlock the dam files.

Let the era of GPUCPU app's commence "Just think using a GPU in a cloud cluster for breaking passwords ammm easy as pie"

EDIT "Results for my GTX275"



lol seems 5870 is 3 times faster than my old GTX 275 but still my GTX275 is at stock...

[fellix_bg]

LOL, looks like ATi's hardware is faster in every instance of GPGPU test around here lately -- ray-tracing, various fractal generators and now this one.

[Earzz]

Looks like that a 5750 isnt supported yet

Unsupported CAL device, need RV670, RV740+ or RV870.

Awesome utility!

[BababooeyHTJ]

Thats just cool. Thanks for the link.

[Talonman]

It runs on 1/2 of my 295 just fine...


At first I didn't think it worked due to me running the 'igrargpu' file, and not the required 'example' file.

Thanks for the post.

Thanks for the post.

In the "readme.htm" file he says

You can manually split range to several GPUs if you have them. For example,

igrargpu.exe /a:b /c:cs /min:5 /max:5 /sf:AAAAA /device:0 archive.rar
igrargpu.exe /a:b /c:cs /min:5 /max:5 /sf:NAAAA /device:1 archive.rar

will open two copies of IGRARGPU and they will utilize both GPUs.

So it is possible to run of multiple GPU's you just need to modify the testrules.cmp file a little before running example.cmp

[Talonman]

Thanks for the tip...

File currently looks like this:
@echo off
if "%1" == "" goto error1
igrargpu.exe /a:r /r:135.txt /d:example.dic %1
goto end
:error1
echo Need file name
:end

Now looks like this:
@echo off
if "%1" == "" goto error1
igrargpu.exe /a:b /c:cs /min:5 /max:5 /sf:AAAAA /device:0 archive.rar
igrargpu.exe /a:b /c:cs /min:5 /max:5 /sf:NAAAA /device:1 archive.rar
igrargpu.exe /a:b /c:cs /min:5 /max:5 /sf:NAAAA /device:2 archive.rar
goto end
:error1
echo Need file name
:end

I run the example.cmp file, have to click 'YES' 3 times, to allow each instance of the program to run, but then the test window just flashes for a micro-jiffe, and I cant see the error.

Do you guys think my file looks correct?

[VVJ]

That utility is damn fast comparing to ARPR utility that recovers with 80 pwd/s on a single 3GHz CPU core. GUI needs to be improved at least to be compatible with a simple Windows GUI. Anyway, Ivan Golubev is da man!

I would try
igrargpu.exe /a:r /r:135.txt /d:example.dic /device:0 %1
igrargpu.exe /a:r /r:135.txt /d:example.dic /device:1 %1
igrargpu.exe /a:r /r:135.txt /d:example.dic /device:2 %1

In the example he gives he is starting each GPU from a different place in the dictionary using the -sf switch, which makes sense because otherwise all the GPU's would work on the same set of passwords.

But since the testfile is so small it might be better to create a larger file, with the same password, else the job would be done before the third GPU gets started.

Yes, it is surprisingly fast. In the readme he states that a Radeon HD4850 is about 20 times faster than a single core on a Q6600 @ 2.4Ghz running optimized SSE2 code.

[Talonman]

I would try
igrargpu.exe /a:r /r:135.txt /d:example.dic /device:0 %1
igrargpu.exe /a:r /r:135.txt /d:example.dic /device:1 %1
igrargpu.exe /a:r /r:135.txt /d:example.dic /device:2 %1

It now looks like this:
@echo off
if "%1" == "" goto error1
igrargpu.exe /a:r /r:135.txt /d:example.dic /device:0 %1
igrargpu.exe /a:r /r:135.txt /d:example.dic /device:1 %1
igrargpu.exe /a:r /r:135.txt /d:example.dic /device:2 %1
goto end
:error1
echo Need file name
:end

When I start the app, I now hit 'Yes' once, and one instance runs, and completely finishes.

Then I get another prompt to let the second instance run, I click 'yes', and it will also completely finish.

Then the third instance runs... Same deal. I give it a 'yes' and it finishes processing successfully.

They don't all run at once.

[Toysoldier]

Ok.
Try this

igrargpu.exe /a:r /r:135.txt /d:example.dic /sl:1 /device:0 %1
igrargpu.exe /a:r /r:135.txt /d:example.dic /sl:744 /device:1 %1
igrargpu.exe /a:r /r:135.txt /d:example.dic /sl:1488 /device:2 %1

the /sl:n switch is telling the gpu to start from a specific line in the dictionary which contains 2230 lines so together the 3 GPU's should cover all lines in the dictionary. I think the -sf switch can only be used when doing a bruteforce attack.

A bruteforce attack on the testfile with lower caps would look something like this ...

igrargpu.exe /a:b /r:135.txt /c:s /min:1 /max:5 /sf:aaaaa /devce:0 %1
igrargpu.exe /a:b /r:135.txt /c:s /min:1 /max:5 /sf:haaaa /devce:1 %1
igrargpu.exe /a:b /r:135.txt /c:s /min:1 /max:5 /sf:paaaa /devce:2 %1


To do a bruteforce attack with a single GPU ..try this

igrargpu.exe /a:b /r:135.txt /c:s /min:1 /max:5 %1

Be warned though ... it takes a loooong time to bruteforce the password.

[Talonman]

Thanks again...

She looks like this now, and they are still running 1 instance at a time.

This is a screen print while the second instance was running:

[Toysoldier]

Have you tried the brute force attack ?

[jspace]

This is a really useful app. However, his other wonderful program IGHASHGPU does support multiple cards out of the box. Not sure when that was implemented, but I would expect it to make its way into this program eventually.

[SocketMan]

And the standard pin number on an ATM/Bank card is just 4 numbers,on the average - would just take a few minutes at most to a ...recover..
Nice utility,now where is my moms wallet
just kidding don't get any ideas kids

[zalbard]

5870, stock clocks.

[EniGmA1987]

here is my 4890 @ 1GHz. This is a "custom" config meant for actual use, not just for a test file:





Here is my config, just rename the RAR file you want to crack to "archive" and put it in the same folder. Or change the config to the right file name each time:
@echo off
if "%1" == "" goto error1
igrargpu.exe /a:b /c:a /min:1 /max:7 archive.rar
goto end
:error1
echo Need file name
:end

[NapalmV5]

[Lightman]

Very nice app!





Thanks Nedjo for the link!

[EniGmA1987]

WOW! 1.1Ghz with 1.31v! Mine barely does 1Ghz with 1.35v Plus my card is locked at 1GHz max anyway.

Those are some really impressive numbers too Lightman :O Do a longer test so you can see your actual average:

@echo off
if "%1" == "" goto error1
igrargpu.exe /a:b /c:a /min:1 /max:7 test.rar
goto end
:error1
echo Need file name
:end
