The script requires two txt files to execute successfully. The first one contains the passwords to be analysed - one password per line - and the second must be a dictionary of weak passwords, like rockyou.txt.
The entropy score used to classify the passwords is the same that is used by KeePassXC: https://keepassxc.org/blog/2020-08-15-keepassxc-password-healthcheck/
