This script uses the "Have I Been Pwned?" API developed by Troy Hunt to determine if a password is in the "Pwned Password" list.

In order to protect the confidentiality of the given password, the script first hashes the password using a SHA-1 algorithm and extracts the first 5 characters of the hash for searching the DB. If the query returns a list of hashes, it means that there's a huge possibility that the password has been compromised.
