Windows 10: Open a administrator command prompt window and change to the directory that contains the downloaded file and enter
certutil -hashfile filename.zip SHA256 into command prompt.Linux: Open a terminal and change to the directory that contains the downloaded file.
Enter SHA256SUM filename.zip into terminal.Mac OS: Open a command line using Terminal in the /Applications/Utilities/ directory then enter
openssl dgst -sha256 filename.zip.If they don’t match, try downloading again and repeat verification process until hashes match or contact support for further assistance if needed.
Verifying the integrity of downloaded files can be done easily using PowerShell instead of Command Prompt. Just use the built-in function “Get-FileHash” and by default, PowerShell will generate the checksum using SHA256. No need to define the algorithm, unless you want to use a different one like SHA512.
