Read on to learn how to use Get-FileHash and PowerShell to generate a file hash!ĭid you know that hashing algorithms, such as SHA-256, are also used when creating SSL certificates? To practice, try generating the file’s hash value using all of the other available algorithms. You now know how to use certutil.exe to create a file checksum. Using certutil.exe to create a file checksum. certutil.exe -hashfile "C:\downloads\VSCodeUserSetup-圆4-1.52.1.exe" SHA256 In the example below, certutil.exe generates the SHA-256 hash of the file C:\downloads\VSCodeUserSetup-圆4-1.52.1.exe, as demonstrated in the resulting screenshot. But, certutil.exe has a feature for creating file checksum’s in Windows using the following hash algorithms:įire up PowerShell or a command prompt to start computing file checksums, using the syntax shown below. The primary purpose of certutil.exe is for certificates. The exact program name is certutil.exe, which is available out-of-the-box. Using CertutilĬertutil is another excellent tool to generate a file’s checksum in Windows. What do you think so far? I know you’re ready to learn the next tool. Despite this, in the absence of other tools, FCIV can still serve as a great alternative.Īt this point, you’ve created MD5 and SHA-1 hash values using the fciv.exe tool.
Microsoft officially declared that FCIV is an unsupported command-line tool. While FCIV is a handy tool for computing file hashes, FCIV is older, and the hashing algorithms are limited to MD5 and SHA-1.
As you can see, the fciv.exe command generated the MD5 hash, by default, for the given file.Ĭomputing both MD5 and SHA-1 checksum using fciv.exe. C:\Tools\fciv.exe C:\downloads\VSCodeUserSetup-圆4-1.52.1.exeĪfter running the FCIV command, you will see a similar result as shown in the screenshot below. If your file is located elsewhere, modify the location appropriately. Run the command below in a command prompt or PowerShell prompt to generate the MD5 checksum of the file VSCodeUserSetup-圆4-1.52.1.exe. Suppose that you’ve installed the FCIV tool in C:\Tools\fciv.exe. The File Checksum Integrity Verifier (FCIV) Microsoft tool was originally introduced in Windows Server 2012 R2 and is available for all future versions. The File Checksum Integrity Verifier (FCIV) Prerequisites for each method of generating checksums will be provided as needed. To follow along, make sure you have at least a computer running Windows 10 or at a minimum Windows Server 2012. Some tools used in this article are built-in or provided by Microsoft some are also from third-party sources. Since this is a how-to article, you will follow the learning-by-doing approach.
