+#### [Password Checker](https://github.com/herokunt/python-scripts/blob/main/password_checker.py)
+Check your passwords against the popular "Have I Been Pwned?" website and find out if they've been leaked in any of the increasingly common data breaches. Your passwords provided to the script will remain secured as only a hash is used, as per the Have I Been Pwned API requires. You can provide passwords inline or through a CSV file, ideal if your password manager (such as KeePassXC) supports exporting data in CSV format (don't forget to delete your file afterwards!)
