使用crypto-js库，简单加密解密

import CryptoJS from 'crypto-js';

const password = '1';
const isopen = true;
class Crypto {
  // 加密
  encrypt(value) {
    if (isopen) {
      return CryptoJS.AES.encrypt(value, password).toString();
    } else {
      return value;
    }
  }
  //解密
  decrypt(value) {
    if (isopen) {
      return CryptoJS.AES.decrypt(value, password).toString(CryptoJS.enc.Utf8);
    } else {
      return value;
    }
  }
}

export default new Crypto();

import Crypto from './Crypto';
const setItem = (key, value) => {
  const encryptValue = Crypto.encrypt(value);
  try {
    sessionStorage.setItem(key, encryptValue);
  } catch (error) {
    console.log(error);
  }
};
const getItem = (key) => {
  if (!key) return null;
  if (!sessionStorage.getItem(key)) return null;
  return Crypto.decrypt(sessionStorage.getItem(key));
};
export default {
  setItem,
  getItem,
};

调用

SS.setItem('1', '123');

console.log("SS.getItem('1')", SS.getItem('1'));

结果
