常见问题
- 为什么显示“无法校验签名”？

- 过期时间准吗？
- exp 以秒为单位的时间戳，按本机时间显示；若设备时间不准会偏差。

FAQ
- Why “signature not verified”?
- This tool only decodes and displays; it holds no key, so it cannot and does not verify the signature.
- Is the expiry time accurate?
- exp is a per-second timestamp shown in local time; if your device clock is off, it will be skewed.
