How to configure Hashcat to append some data?

[Lishoo]

Integer overflow detected in keyspace of mask: ?2?2?2?2?2?2?2?2?2?2?2?2?2?2?2?2?3?3?3?3?3?3?3?3?3?3?3?3?3?3?3?3

The problem now is not the syntax, but the infeasibility.



Just do the math. It's mathematically infeasible. You are trying to brute-force 16 unknown bytes: 16*16*16*...*16*16*16 = 16^16 = 18,446,744,073,709,551,616

Thank you for your reply, this was the part that I didn't understand



Removing two bytes runs ok

Code:

hashcat -m 1400 -a 3 -w 3 --hex-charset --custom-charset2 30313233343536373839414243444546 --custom-charset3 00 4BC2940C6460134A90194D9D0EA1920792869C779E6909C9E3F15C2E0FA46857 3030?2?2?2?2?2?2?2?2?2?2?2?2?2?2?3?3?3?3?3?3?3?3?3?3?3?3?3?3?3?3
