获取cookie

  //获取cook
const GetCookie = (getName) => {
  let name = getName + "=";
  let ca = document.cookie.split(';');
  for (let i = 0; i < ca.length; i++) {
    let c = ca[i].trim();
    if (c.indexOf(name) == 0) {
      try {
         return DecryptByDES( c.substring(name.length, c.length),COOKIE_PUBLICKEY)
      }catch (err){
        console.log(err);
        return ''
      }
    }
  }
  return "";
};

设置cookie

//保存用户信息
const SetCookie = (saveName, value) => {
  let days = 30;
  let d = new Date();
  let saveValue = EncryptByDES(value,COOKIE_PUBLICKEY);
  d.setTime(d.getTime() + (days * 24 * 60 * 60 * 1000));
  let expires = "expires=" + d.toGMTString();
  document.cookie = saveName + "=" + saveValue + "; " + expires;
};

EDS 解密

//EDS 解密
const DecryptByDES = (ciphertext, key) => {
  let keyHex = CryptoJS.enc.Utf8.parse(key);
  let decrypted = CryptoJS.DES.decrypt({
    ciphertext: CryptoJS.enc.Base64.parse(ciphertext)
  }, keyHex, {
    mode: CryptoJS.mode.ECB,
    padding: CryptoJS.pad.Pkcs7
  });
  return decrypted.toString(CryptoJS.enc.Utf8);
};

EDS加密

//EDS加密
const EncryptByDES = (message, key) => {
  let keyHex = CryptoJS.enc.Utf8.parse(key);
  let encrypted = CryptoJS.DES.encrypt(message, keyHex, {
    mode: CryptoJS.mode.ECB,
    padding: CryptoJS.pad.Pkcs7

  });
  return encrypted.toString();
};
