// Encrypt
var ciphertext = CryptoJS.AES.encrypt('my message', 'secret key 123');
// Decrypt
var bytes = CryptoJS.AES.decrypt(ciphertext.toString(), 'secret key 123');
var plaintext = bytes.toString(CryptoJS.enc.Utf8);
console.log(plaintext);<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.2/rollups/aes.js"></script>回答by Ankita
encrypted.toString()will return the correct string value.
encrypted.toString()将返回正确的字符串值。
var encrypted = CryptoJS.AES.encrypt("Message", "Secret Passphrase");
alert(encrypted.toString());
var decrypted = CryptoJS.AES.decrypt(encrypted, "Secret Passphrase");<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.2/rollups/aes.js"></script>回答by ajimae
If you are building a react or nodejs app, you can simply use this library ncrypt-jsto encrypt and decrypt your data.

// or
// let encryptData = encrypt('super secret data', 'secret_key');
console.log(encryptData); // 11ab949601eb136f58ac3fe846e30d76.f9ce133b20adc35eef32af95957547abbb6fbfc5cb91cd14f5b0a088bd031883963cde1a56fd62fe2aeb75451a065d21
var decryptedData = ncrypt.decrypt(encryptData);
// or

import ncrypt from 'ncrypt-js'; // or import { encrypt, decrypt } from 'ncrypt-js';
const encryptData = ncrypt.encrypt('super secret data', 'secret_key');
