just create the hashcat mask file (a.hcmask) manually:
note: of course you can modify this in any shape or form you like, e.g. using ?l (lowercase letters) instead of ?a (which is much huger, i.e. ?l?u?d?s)
Code:
?l?u,?l?d,?1?a?a?a?a?2?2?2
?l?u,?l?d,?1?a?a?a?a?a?2?2?2
?l?u,?l?d,?1?a?a?a?a?a?a?2?2?2
Code:
hashcat -m 2500 -a 3 -w 3 hash a.hcmask
note: of course you can modify this in any shape or form you like, e.g. using ?l (lowercase letters) instead of ?a (which is much huger, i.e. ?l?u?d?s)
