  3. To compute the hash, run this PowerShell command (replace the path with your program’s path):
    powershell /c "(Get-AppLockerFileInformation -Path 'D:\Program Files\BaiduNetdisk\BaiduNetdisk.exe').Hash.HashDataString"
  4. Only PowerShell’s Get-AppLockerFileInformation method is supported for valid hashes  other tools may produce incompatible formats.
