In one our project, we have used 'crypto-js' library. http://github.com/brix/crypto-js

import * as CryptoJS from 'crypto-js';

encryptData(data) {

    try {
      return CryptoJS.AES.encrypt(JSON.stringify(data), this.encryptSecretKey).toString();
    } catch (e) {
      console.log(e);
    }
  }

  decryptData(data) {

    try {
      const bytes = CryptoJS.AES.decrypt(data, this.encryptSecretKey);
      if (bytes.toString()) {
        return JSON.parse(bytes.toString(CryptoJS.enc.Utf8));
      }
      return data;
    } catch (e) {
      console.log(e);
    }
  }
