Why isn't this working, and can someone fix it?
Hello! I would like to know why this isn't working and if someone could fix it for me, i'm trying to do a bruteforce but it just won't work, and I don't understand what i'm doing wrong, hashcat64 -m0 --show --username -a3 -o cracked.txt.txt hash.txt.txt
I think you need to re-order the arguments, so hash.txt needs to come earlier on, --show doesn't apply and -a3 requires a mask to be specified. The following works for me:

hashcat64.exe -O -w3 -m0 --username hash.txt.txt -a3 ?a?a?a?a -o cracked.txt

where hash.txt.txt is:
