mask files

[memetik]

Hi,

I just encoutered a strange behavior with the mask files (.hcmask)

With this in the mask file :

?l,?d,?1?1?1?1?1?2?2?2?2
?u,?d,?1?1?1?1?1?2?2?2?2

The calculated keyspace is normally the same for both line : 118 813 760 000.
But, when you execute it, the second line get processed with a keyspace of 3 802 040 320 000. And of course, the time/cost is much higher.

Win7-64 / cudaHashcat64 1.35
command : cudaHashcat64.exe -m 5100 -a 3 --remove -o hashs.txt.out hashs.txt test.hcmask

If I execute it with only one line in the file at a time, everything is fine.

So, I was testing another syntax to try isolating the problem :

?l?l?l?l?l?d?d?d?d
?u?u?u?u?u?d?d?d?d

1st line OK
2nd line OK

abcdefghijklmnopqrstuvwxyz,?d,?1?1?1?1?1?2?2?2?2
ABCDEFGHIJKLMNOPQRSTUVWXYZ,?d,?1?1?1?1?1?2?2?2?2

1st line OK
2nd line NOK

At this point, it seems related to the [1],[2],[3],[4],[mask] syntax.

Furthermore, if I use :

?l,?d,?1?1?1?1?1?2?2?2?2
?u,?d,?1?1?1?1?1?2?2?2?2
?l,?d,?1?1?1?1?1?2?2?2?2

1st line OK
2nd line NOK
3rd line NOK

And if I invert the line :

?u,?d,?1?1?1?1?1?2?2?2?2
?l,?d,?1?1?1?1?1?2?2?2?2

1st line OK
2nd line NOK

I was looking in docs, forums, trac, etc. to find a possible explanation, but nothing. So I turn this to you for a look with new eyes.

thank you for your time.



edit :
It seems there is some kind of interaction between the line when the charsets are not from the same "defaults" charsets.

abc,?1
123,?1

1st line keyspace = 3
2nd line keyspace = 6 ???

From my first exemple :

?l,?d,?1?1?1?1?1?2?2?2?2
?u,?d,?1?1?1?1?1?2?2?2?2

1st line keyspace = 118 813 760 000
2nd line keyspace = 3 802 040 320 000 (118 813 760 000 * 32) NOK

With the example on the wiki :

?d?l,test?1?1?1
abcdef,0123,ABC,789,?3?3?3?1?1?1?1?2?2?4?4?4?4
company?d?d?d?d?d
?l?l?l?l?d?d?d?d?d?d

1st line keyspace = 46 656
2nd line keyspace = 58 773 123 072 (45 349 632 * 1 296) NOK
3rd line keyspace = 100 000
4th line keyspace = 45 697 600 000
