What am I doing wrong?

[M@LIK]

when u putting [?l?u?d] as a mask.. its only trying [aA1, aA2.. aB1 aB2..]
u have to define the charsets.. then putting the mask..
ur command line should be like this::

Code:

hashcat-cli32 -m400 -a3 -oout.txt -n4 -1 ?l?u?d hash.txt ?1?1?1?1?1?1?1?1

note::
1- [hash.txt] should be in the same folder.
2- [out.txt] will be also in the same folder.
3- [?1] means one letter.. so if u want the length=3 >> ?1?1?1 ,, length=4 >> ?1?1?1?1
happy cracking ; )
