It is often claimed that passwords do not get saved as plaintext anywhere in systems, and even the system administrator does not know your password. Given what you learned about hash functions. Explain how such a claim is possible. In other words, how do systems perform authentication without having to store passwords in a format that can be read by the system administrators. Authentication is primarily the process of verifying that provided password is correct. Design a simple authentication system and implement the following two methods: def signup(username, password      '''store the user credential so that the system knows how to authenticate the user in the future (when login() gets called).''' def login(username, password):      '''returns True, if the provided username and password are correct'''

Cryptography

Cryptography is a term used in computer science to describe secure information and communication techniques that transform messages in difficult-to-decipher ways using mathematical concepts and a set of rule-based calculations known as algorithms.
