An example of base64 usage in cryptojs

cryptojs_base64_encrypt_decrypt.js

var CryptoJS = require("crypto-js");//replace thie with script tag in browser env

//encrypt
var rawStr = "hello world!";
var wordArray = CryptoJS.enc.Utf8.parse(rawStr);
var base64 = CryptoJS.enc.Base64.stringify(wordArray);
console.log('encrypted:', base64);

//decrypt
var parsedWordArray = CryptoJS.enc.Base64.parse(base64);
var parsedStr = parsedWordArray.toString(CryptoJS.enc.Utf8);
console.log("parsed:",parsedStr);

Hallo can someone explain me the flow also how to decrypt back, if that was encrypted this way?

i am confused currently as still new to cryptography

// Code Section
{

function encrypt(data) {

const val = cryptoJS.enc.Utf8.parse(JSON.stringify(data));

const encrypted = cryptoJS.AES.encrypt(val, key, { iv: IV }).toString();

let b64 = cryptoJS.enc.Base64.parse(encrypted).toString(cryptoJS.enc.Hex);

return b64;

}
}

This gist saved me! Thank you so much!

thanks for this
