Verifying the Demo Package Integrity

Function

Check the integrity of downloaded demo packages, that is, check whether the packages are tampered with or packets are lost during download.

Procedure

1. Download a demo package based on the download path of the Android/Windows/macOS/Electron demo in Downloading Demo Installation Packages.

2. Download the demo package to your device.

3. Open the CLI and run the following command to generate the SHA-256 value of the downloaded demo package. In the command, D:\hmwsdk-win-demo-win32.zip indicates the local path for storing the package and the package name. Replace it with the actual value.

certutil -hashfile D:\hmwsdk-win-demo-win32.zip SHA256

The following is an example of the command output:

SHA256 D:\hmwsdk-win-demo-win32.zip hash:
67244236887ae862adbe2c8ee2f4612e5d483d0562087c7f084484318655d702 
CertUtil: -hashfile Command executed

Compare the generated SHA-256 value with that listed in the package download path table. If they are the same, no tampering or packet loss occurred during download.
