Bug using markov chains?

[eljolot]

I was Using Markov chains And I aumented the keyspace using a threshold=8 And well I got this, Maybe is my error.

That's my code

Code:

./oclHashcat-plus32.bin -a 3 -m 0          '/root/Desktop/m.txt'            ?a?a?a?a?a?a?a?a?a?a?a       --outfile-format=3  --remove --outfile=/root/Desktop/founded2.txt    --markov-threshold=8

Code:

I don't see anything wrong with your command so it may be a bug, but I cannot reproduce it.

What happens if you use other threshold values? Did you alter hashcat.hcstat in any way?

[eljolot]

With other values of threshold works fine, from 11 like ?a and foward I got the same error, I didn't touch the default .hcstat I even generated another one from other dicctionary and nothing, my graphics card is and RADEON-HD 6310M. maybe that could be the problem?

that's was my new try, I used 12 ?a

Code:

./oclHashcat-plus32.bin -a 3 -m 0         '/root/Desktop/hashcrack/pendientes.txt'           ?a?a?a?a?a?a?a?a?a?a?a?a       --outfile-format=3  --remove --outfile=/root/Desktop/founded2.txt    --markov-threshold=8 --markov-hcstat '/root/Desktop/test.hcstat'

[atom]

can you try -t instead of --markov-threshold please?

[eljolot]

Got the same =(

Code:

./oclHashcat-plus32.bin -a 3 -m 0  -t 8 '/root/Desktop/hashcrack/pendientes.txt'  ?a?a?a?a?a?a?a?a?a?a?a?a      
--outfile-format=3  --remove --outfile=/root/Desktop/founded2.txt --markov-hcstat  '/root/Desktop/test.hcstat'

It's really low-end card, possibly this will be an issue.

[eljolot]

I guess This was solved in the new version, tried again to see, And found that hashcat detects other kernel for my card.

Code:

./oclHashcat-plus32.bin -a 3 -m 0   '/root/Downloads/32_hex_7_days.txt'   ?a?a?a?a?a?a?a?a?a?a?a?a            --outfile-format=3  --remove --outfile=/root/Desktop/founded.txt --markov-threshold=8

Code:

The kernel is different and now I don't get this error.

I guess this thread can be closed

Thanks for information. Thread closed.
