hashcat -h | grep -i "$HASH$"

Without custom rules

hashcat -m $CODE$ file.hash /usr/share/wordlists/rockyou.txt

Custom rules

Create a custom rule

john --wordlist=/usr/share/wordlists/rockyou.txt file.hash

With custom rule

john --wordlist=/usr/share/wordlists/rockyou.txt --rules=sshRules file.hash

Custom rule

To create a custom rule, it is needed to append the rule at the end of /etc/john/john.conf using a format.

In this example we will create a custom rule named "sshRules"
