System: Windows 7 64 bit, Driver 285.62 GTX470, oclhashcat-plus beta 47

General problem:

- Something got wrong with -a 3. It does not work for all length on the following algos: 0, 10, 11, 20, 21, 30, 40, 100, 101, 110, 111, 112, 120, 121, 122, 130, 131, 132, 140, 141, 300, 900, 1000, 1100, 1400, 1410, 1420, 1500, 1700, 1710, 1720, 1722, 2400, 2600, 2611, 2711, 2811, 3000 and 3100. As you can see, heavy algo seems to be untouched by this problem.

- The progress and reject counter are wrong, see attached picture.

Specific problems

-m 130 sha1(unicode($pass).$salt), -a 1 and -a 7 fails for all length.
-m 131 MSSQL(2000), -a 1 and -a 7 fails for all length.
-m 132 MSSQL(2005), -a 1 and -a 7 fails for all length.
-m 1710 sha512($pass.$salt), -a 1, -a 6 and -a 7 fails for all length.
-m 1800 sha512crypt, SHA512(Unix), length 15 in -a 1 and -a 6 fails. Length 4 and 8 in -a 7 fails.
-m 2711 only dictionary (-a 0) attack works.
-m 2811 only dictionary (-a 0) attack works.

- I get the ERROR: cuStreamSynchronize() 999 on the following attack line for -m 1800 and -m 2100:
cudahashcat-plus64.exe -a 3 -d 1 -m 1800 -o found.txt --bf-min 4 --bf-max 4 -1 ?s?d?u?l hash.txt ?u?d?s?d

Thanks mastercracker!

This is interessting. The same happens on AMD, so maye there is a shared bug.

v48 is up but this is only compiled with cuda 5.0. there should be no changes to the stated bugs. there is no need to test again before i fixed them.

cuda 5.0 however produces massive performance increases, see here: https://twitter.com/hashcat/status/236218225082388480

fixed:

Quote:-m 141 Nothing works

New version is up, pls test

how can i reproduce this?

For further Nvidia testing, it seems that I need to update the driver I have. I currently get the CuModuleLoad() 209 error. I will try updating it when I'll get back home.

Yep, you need 304.x on Linux, not sure which version to use on windows.

It happens for example with this command line:

cudahashcat-plus64.exe -a 1 -d 1 -m 3200 -o found.txt hash.txt dic1.txt dic1.txt
So you can try combination attack on blowfish and see if you get the same thing. Otherwise I can provide you with the hash.txt and dic1.txt files. This is for NVidia with my GTX470 but the same happens with AMD HD5750. Also note that for the dictionary attack (-a 0), both counters work fine in both systems (AMD and NVIDIA).

You need to download a 883MB package just to install the beta driver needed to run latest betas of cudacats.
Crazy if you ask me.

@Rolf:: You sure?
I grabbed the latest beta driver from here (304.79, Only ~200Mb):

Forget to say, it feels "buggy" for me, even the WindowsExperinceIndex rating went down :(
