# 如何檢查官網升級包的 SHA256sum

Keystone 錢包支持校驗固件升級包的 SHA256sum。此功能可有效幫助用戶檢驗固件升級文檔是否從 Keystone 官方網站下載。

**校驗方法如下：**

1\. 從[官網下載固件升級包](https://keyst.one/firmware)，將解壓後得到的 “update.zip” 文檔拷貝到 MicroSD 記憶卡並插入 Keystone 硬件錢包，開機。

2\. 將 Keystone 錢包顯示的 SHA256 與官網展示的 SHA256 進行比對。

**用戶也可以選擇不相信 Keystone 錢包顯示的數據，直接使用電腦 adb 工具查看固件升級包的 SHA256 並與官網展示的 SHA256 進行比對**

1\. 從[官網下載固件升級包](https://keyst.one/firmware)，以 V1.1.1 單幣種固件版本為例。

3\. 解壓固件升級包 “V1.1.1-BTC-Only”，得到 “update.zip” 壓縮包文檔。

4\. 打開電腦 adb 工具，運行以下命令：

* Windows PowerShell：certutil -hashfile 壓縮包文檔路徑 SHA256
* MacOS Terminal：shasum -a 256 / 壓縮包文檔路徑
* Linux：sha256sum / 壓縮包文檔路徑

5\. 將結果與官網展示的 SHA256 進行比對。如果結果不一致，請謹慎升級。
