What is salt in hashing?

In cryptography, a salt is random data used as an additional input to a one-way function that hashes data, such as a password. Salts are used to keep passwords safe while they are being stored. Historically, only the password’s cryptographic hash function was maintained on a system, but over time, additional precautions were developed to prevent the identification of duplicate or common passwords. One such prevention is salting.

Encryption: Encryption is the process of encoding plain text or any information in such a way that only authorized people can read it with a corresponding key so that confidential data can be protected from unauthorized persons. 

Hashing: Hashing converts any amount of data into a fixed-length hash that cannot be reversed. It is widely used in cryptography. The hash allows us to validate if the input has changed even slightly, if it is changed the resulting hash will be different. In this article, we are going to learn the  Salted Password Hashing technique. It includes converting an algorithm to map data of any size to a fixed length.

In this article, we are going to know how to hash passwords in python.

A strong password provides safety. Plain text passwords are extremely insecure, so we need to strengthen the passwords by hashing the password. Hashing passwords is a cheap and secure method that keeps the passwords safe from malicious activity. Password hashing generates a unique password for every text, even if the plaintext password is the same.
