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);

thinks ,i do not know why need CryptoJS.enc.Utf8.parse()?

this does not convert JSON object

Very helpful thank you!

this does not convert JSON object

If i've understood what you're saying, you just need to do this:

//encrypt
var myObj = { foo: "bar" };
var rawStr = JSON.stringify(myObj);
var wordArray = CryptoJS.enc.Utf8.parse(rawStr);
...

Version with only one line each:

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

//
var rawStr = "hello world!";

//encrypt
var base64 = CryptoJS.enc.Utf8.parse(rawStr).toString(CryptoJS.enc.Base64);

//decrypt
var parsedStr = CryptoJS.enc.Base64.parse(base64).toString(CryptoJS.enc.Utf8);

Someone may find it useful.
I noticed that Kubernetes encodes ssh private and public keys in its secrets (may SSL keys too) with base64 adding the trailing line at the end of a key.
For example, CryptoJS works the way similar to

$ echo -n 'Hello World' | base64
$ SGVsbG8gV29ybGQ=

-n means that it does not add a trailing line. While keys in Kubernetes are encoded using a trailing line at the end (you can see a different result)

$ echo 'Hello World' | base64
$ SGVsbG8gV29ybGQK

So to make sure the keys are encoded the way it is meant by Kubernetes I tried the solution in Postman with a new line character - (plainText + '\n'):

var plainText = pm.environment.get('github_ssh_private_key');
var encoded = CryptoJS.enc.Base64.stringify(CryptoJS.enc.Utf8.parse(plainText + '\n'));
pm.environment.set("github_ssh_private_key_base64", encoded);

awesooooom

this saves my day a lot, thanks!

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
