WPA speed problem comparing to v1.31

[Mem5]

Hi there,

I have downloaded the last oclhashcat (v1.32) , but I have WPA speed problem comparing to v1.31 :

Win 7 / GPU R9-290 / Driver AMD 14.9

Code:

oclHashcat-1.31\oclHashcat64.exe --remove --gpu-temp-abort=90 -w 3 -m 2500 test.hccap wpa-dic.txt -r best64.rule oclHashcat v1.31 starting... Removing duplicate hashes...

v1.31 works fine, ~157 kH/s is ok.

Same command with v1.32 :

Code:

oclHashcat-1.32\oclHashcat64.exe --remove --gpu-temp-abort=90 -w 3 -m 2500 test.hccap wpa-dic.txt -r best64.rule oclHashcat v1.32 starting... Removing duplicate hashes...

v1.32 : only 3231 H/s

Any help please ?

1.32 uses AMP kernel (candidates calculated on GPU), therefore you need bigger wordlists as with 1.31.

[philsmd]

Furthermore, there are also some other (minor) changes, which could influence the speed difference between the 2 versions
For instance, did you notice that 1.31 did reject more than 1/3 of the plains, see:
Rejected.......: 197063/557460 (35.35%)

while 1.32 did not (see also : https://hashcat.net/trac/ticket/515 , plains are no more aggressively rejected before the rules are applied).

This doesn't really significantly influence the cracking speed, at least not that much compared to the amp kernels (but if you have large dictionaries, it may increase the overall cracking time a little bit).

Same here with my R9 270

mask and dict for "WPA/WPA2" with oclhascat 1.32
and in the Abcdef.dict only one word "Abcdef"

I use both v 1.31 and
v 1.32 (no rejection compare to 1.31)

[Mem5]

1.32 uses AMP kernel (candidates calculated on GPU), therefore you need bigger wordlists as with 1.31.

Ok, it is a regression? What's the solution ? I can not use small wordlists anymore ?

Furthermore, there are also some other (minor) changes, which could influence the speed difference between the 2 versions
For instance, did you notice that 1.31 did reject more than 1/3 of the plains, see:
Rejected.......: 197063/557460 (35.35%)
while 1.32 did not

OK, but the 35% rejected was because passwords length were not between 8-64 chars ; so do you mean that v1.32 can test password <8 or >64 chars ?

[undeath]

OK, but the 35% rejected was because passwords length were not between 8-64 chars ; so do you mean that v1.32 can test password <8 or >64 chars ?

No. Previous versions (wrongly) rejected words before applying rules. The new version only after applying rules.

[Mem5]

Ok I got it. Thanks undeath.

So I can not use small wordlists anymore with v1.32 ? What is is considered as a small/big wordlist ?

[atom]

Well you can. If you really want to use small wordlists as before (and then adding rules), you can use hashcat in --stdout mode and pipe it to oclHashcat. In that case you will get the same speed with 1.33 as with 1.31 for small wordlists
