Full Version: Bug using markov chains?

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

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?
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'

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

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

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

Thanks for information. Thread closed.
