Cipher a string using crypto-js with hex encoding to make it url friendly

Question

I am using crypto-js by brix. I have this function below that handles the encryption of a plain text.

import CryptoJS from \'crypto-js\'
import AES

You would likely want to do:

export function dec(cipherText){
   var bytes = CryptoJS.AES.decrypt(cipherText, SECRET);
   var hex = bytes.toString(CryptoJS.enc.Hex);
   var plain = bytes.toString(CryptoJS.enc.Utf8);
   return [hex, plain];
}

This takes the encrypted base64 string and will return the decrypted plaintext and hexadecimal.

EDIT: In regards to your comment and edited question:

const SECRET = 'I am batman'

function enc(plainText){
    var b64 = CryptoJS.AES.encrypt(plainText, SECRET).toString();
    var e64 = CryptoJS.enc.Base64.parse(b64);
    var eHex = e64.toString(CryptoJS.enc.Hex);
    return eHex;
}

function dec(cipherText){
   var reb64 = CryptoJS.enc.Hex.parse(cipherText);
   var bytes = reb64.toString(CryptoJS.enc.Base64);
   var decrypt = CryptoJS.AES.decrypt(bytes, SECRET);
   var plain = decrypt.toString(CryptoJS.enc.Utf8);
   return plain;
}

The end result takes the base64 string, makes it hexadecimal and returns the decrypted string.
