Python Modules Used: Requests, Hashlib, Sys

Description- Password Security is always a major concern. So, I developed a Password Checker which checks whether the password is safe or it has been used at any point of time on internet based on the database of API named api.pwnedpasswords.com. SHA1 Hashing algorithm is used. The Project uses 'K Anonymity' approach. Here only first 5 characters are sent over API and the returned output is checked. The API delivers a more secure response to data matched on our machines to verify whether or not the password has been used before.
