    }

        $passphrase = empty($passphrase)?config('custom.aes.openssl.key'):$passphrase;

        $iv = empty($iv)?config('custom.aes.openssl.iv'):$iv;
        $res = openssl_decrypt(base64_decode($data),$cipher_algo,$passphrase,$options,$iv,$tag);
        return json_decode($res,true);// json_decode 将字符串转为PHP变量，true 返回 array 而非 object
    }
}

通过use在其他地方引入，使用$this->encrypt $this->decrypt调用。
