A command line tool to check if an email address has been pwned. Uses the https://haveibeenpwned.com/ api.
Through NPM
npm install -g pwned-checker
Running
Use pwned-checker -e <email address>
The address will be saved along with the last time that it ran in a configuration file at ~/.pwned-checker/config.json. This will make it so you will only see the report for the pwned accounts once per email address.
