Identical username password case

[dodo]

Hello,

My hash file is in format username:password
Is there a way to catch those cases when username=password?

cut -d: -f1 hashfile >usernames, then use usernames as a wordlist.

Thanks epixoip for the update, so I understand that there's no rule or built-in method to catch those cases in hashcat, correct?
