How does crypto-js.HmacSHA256 work?

crypto-js.HmacSHA256 is a method in the crypto-js library that computes the HMAC-SHA256 message authentication code for the provided message and key, using the SHA256 hash function and the HMAC construction. The HMAC-SHA256 algorithm takes two inputs: a message and a secret key. It produces a fixed-size output called a message authentication code (MAC) that can be used to verify the integrity and authenticity of the message. The MAC is computed by applying a hash function (SHA256 in this case) to the concatenation of the key and the message, with some additional padding and processing steps to ensure security. The crypto-js.HmacSHA256 method returns the MAC as a WordArray object, which can be converted to a string or a byte array as needed.

const CryptoJS = require("crypto-js");

const message = "Hello, world!";
const secretKey = "secret123";
const hash = CryptoJS.HmacSHA256(message, secretKey).toString(CryptoJS.enc.Hex);

console.log(hash); // output: 9628e3e3c9faeebb2b0a8a301a2d69c0b7e1b365a1b8c0b372f9cf0c0445cf35

In this example, we first require the crypto-js library. We then create a message variable containing a string, and a secretKey variable containing another string. We then pass these two values as arguments to the CryptoJS.HmacSHA256() function, which calculates the HMAC-SHA256 hash of the message using the secretKey. Finally, we convert the resulting hash to a hexadecimal string using CryptoJS.enc.Hex, and log it to the console.
