Check whether password is known to have been exposed in a data breach
Pwned Passwords are hundreds of millions of real world passwords exposed in data breaches. This exposure makes them unsuitable for ongoing use as they are at much greater risk of being used to take over other accounts.
This script offers 2 methods to check whether a password has been exposed in an uncovered breach
1 Online check implemented in such a way that the password to be checked does not need to be sent to the remote database server.
2 Local check against a copy of the pawned passwords database.
Since the local copy of the database requires nearly 20 GB of disk space and a download of more than 10 GB of compressed data the access via the online check should be preferred, if the compatible with operational and security requirements.
