Explanation

By computing the downloaded application's checksum (e.g., SHA-256 or MD5) and comparing it against the official hash published by the software vendor, the technician can verify the file's integrity and authenticity. A matching hash confirms the application is genuine and unaltered, whereas any discrepancy indicates a potentially illegitimate or tampered file.
