Help with rules (5 letter word - 0000-9999 - 6 letter word)

[b8vr]

Looking at your headline, what you actually want is to have 4 digits between the 2 wordlist, correct?

I would run hashcat -a6 5letter-wordlist ?d?d?d?d --stdout > 5letter-wordlist-digits

After that you could run

hashcat -a1 hashlist 5letter-wordlist-digits 6letter-wordlist

And then repeat the process with the 6letter-wordlist
