How do you crack an AS-REP hash with hashcat?

The extracted AS-REP hash must be slightly modified by inserting `$23` after `$krb5asrep$` to match hashcat's format. Then run hashcat with mode 18200, specifying a dictionary file and output location. For example: `hashcat -m 18200 '$krb5asrep$23$...' /usr/share/john/password.lst -o found.txt --force`. Successful cracking reveals the user's plaintext password.
