SHA256 Hash generating algorithm

you need to import crypto module and call hmac method

// get crypto module 
const crypto = require("crypto"); 
// string to be hashed 
const str = "I need to be hashed 😃!"; 
// secret or salt to be hashed with 
const secret = "This is a company secret 🤫"; 
// create a sha-256 hasher 
const sha256Hasher = crypto.createHmac("sha256", secret); // hash the string 
// and set the output format 
const hash = sha256Hasher.update(str).digest("hex"); 
// A unique sha256 hash 😃 
console.log(hash); // d22101d5d402ab181a66b71bb950ff2892f6d2a1e436d61c4fb1011e9c49a77a
