CHECKSUM EXAMPLE HOW TO
The remarks at the top show how to use the script, and there is also a usage prompt if no parameter is provided or the first parameter is a file that doesn’t off Here’s a script I wrote that takes the information in this article and shows or checks the checksum. In the subsequent versions of Windows the case doesn’t matter. Be sure to type, for example, not “md5” but “MD5”. Hash Algorithms: Note that on Windows 7, the hash algorithms are case-sensitive. PS C:\> $(CertUtil -hashfile C:\file.img MD5) -replace " ",""Īvailable hash algorithms: MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512 SHA256 checksum example ( sha256sum): C:\> certUtil -hashfile C:\file.img SHA256Ĭ:\> CertUtil -hashfile C:\file.img MD5 | findstr /v "hash" MD5 checksum example ( md5sum): C:\> certUtil -hashfile C:\file.img MD5

In this note i will show the examples of how to make md5sum and sha256sum of a file in Windows from the command line.Ĭool Tip: zip and unzip from the command line in Windows!
