Mask attack for unique characters?

[jordan77]

Hello

I want to crack by a rule which only uses alphabetic characters with no duplicates allowed. So for example ABCDEFGH wouldbe allowed but AABCDEFG not because of the double A
So if i would look for a 9 char password it would be 26*25*24*23*22*21*20*19*18 possible combinations.

Is there a mask rule i can use for this? or i need to make a 'wordlist' ?

the best solution would probably be to write a script that outputs exactly what you want, and feed it to hashcat via stdin.

You're lucky I've recently added that feature to maskprocessor v0.69. You can control the number of concurrent chars with the -q parameter. You can get it here: http://hashcat.net/wiki/doku.php?id=maskprocessor

Take a look here for comparison:

Code:

root@sf:~/maskprocessor-0.70# ./mp64.bin ?u?u?u?u?u?u?u?u?u | head -10
AAAAAAAAA
AAAAAAAAB
AAAAAAAAC
AAAAAAAAD
AAAAAAAAE
AAAAAAAAF
AAAAAAAAG
AAAAAAAAH
AAAAAAAAI
AAAAAAAAJ

Code:

root@sf:~/maskprocessor-0.70# ./mp64.bin ?u?u?u?u?u?u?u?u?u -q 2 | head -10
ABABABABA
ABABABABC
ABABABABD
ABABABABE
ABABABABF
ABABABABG
ABABABABH
ABABABABI
ABABABABJ
ABABABABK
