Generate File Hash in Windows

:: Generate File Hash
::
:: The "Get-FileHash" cmdlet Computes the hash value for a file by using a
:: specified hash algorithm.
::
:: The default hashing algorithm is SHA256, but you can use any of the following
:: algorithms:
::
:: - SHA1
:: - SHA256
:: - SHA384
:: - SHA512
:: - MACTripleDES
:: - MD5
:: - RIPEMD160

:: Example 1
::
:: This example uses the Get-FileHash cmdlet to compute the hash value for the
:: Powershell.exe file. The hash algorithm used is the default, SHA256. The output
:: is piped to the Format-List cmdlet to format the output as a list.
Get-FileHash $pshome\powershell.exe | Format-List

:: Example 2
::
:: This command uses the Get-FileHash cmdlet and the SHA384 algorithm to compute
:: the hash value for an ISO file that an administrator has downloaded from the
:: Internet. The output is piped to the Format-List cmdlet to format the output
:: as a list.
Get-FileHash Contoso8_1_ENT.iso -Algorithm SHA384 | Format-List

:: Example 3
::
:: Running the Powershell command from a batch file:
@echo off
if exist "%1" (
    echo.
    echo.Generating hash...
    PowerShell -NoProfile -NoLogo -ExecutionPolicy unrestricted -Command "& Get-FileHash '%1' -Algorithm SHA256 | Format-List"
) else (
    echo.File not found.
)
