HarmonyOS CryptoJS Des解密问题

使用"@ohos/crypto-js": "^2.0.3"进行解密，这是解密的代码：

declare interface KeyOption {
  value: string,
  key?: string
}

export class CryptoUtil {
  private static readonly secretKey:string = "tcxyctxy";
  private static readonly uintArray = new Uint8Array([1,2,3,4,5,6,7,8])

  static encrypt(params:KeyOption):string{
    let key:string = (params.key == undefined || params.key.length === 0) ? CryptoUtil.secretKey : params.key;
    if (params.value.length === 0){
      return "";
    };
    const encryptStr: string = CryptoJS.DES.encrypt(
      params.value,
      CryptoJS.enc.Utf8.parse(key),
      {
        iv:CryptoJS.lib.WordArray.create(CryptoUtil.uintArray),
        mode: CryptoJS.mode.CBC,
        padding: CryptoJS.pad.Pkcs7
      }
    ).toString();
    return encryptStr;
  }

  static decrypt(params:KeyOption):string{
    LogUtil.error(`decrypt入参:${params.value}`)
    let key:string = (params.key == undefined || params.key.length === 0) ? CryptoUtil.secretKey : params.key;
    if (params.value.length === 0){
      return "";
    };
    let result: string = CryptoJS.enc.Utf8.stringify(
      CryptoJS.DES.decrypt(
        params.value,
        CryptoJS.enc.Utf8.parse(key),
        {
          iv:CryptoJS.lib.WordArray.create(CryptoUtil.uintArray),
          mode: CryptoJS.mode.CBC,
          padding: CryptoJS.pad.Pkcs7
        }
      )
    );
    LogUtil.error(`decrypt结果:${result}`)
    return result;
  }
}

上面解密得到的结果是：登录失败，账号与密码错误或者该账号被禁用！但是在HarmonyOS上面解密得的结果却是\udb05\udee8\u0012˼v\ud963\udd26\u001f�楏��密码锠ޤ+(ꑀ泌��˚:Zgԫ\u001f¼；应该怎么修改代码才能得到正确的结果？
