Is there a built-in checksum/hash utility on Windows 7?

  • Not my area, but Powershell, the build in scripting language, can probably do it.

    Is this one of those goofy "I'm not allowed to install any 3rd party software" requirements? If so, try googling for "PowerShell SHA1 hash" and you should get some scripts/cmdlets that will run on the built-in PowerShell using MS's Crypto APIs.

    Note, the best answer (for me) is the 2nd answer, which has many more votes than the answer chosen by the asker. To the reader: look below, for the "certutil.exe" option.

There is a built in utility, as specified in this other answer.

You may, however, wish to use this freeware app called HashTab that integrates neatly with Windows Explorer by registering a... well, a tab in the properties dialog of files. It's pretty sweet.

    I prefer HashCheck over HashTab, primarily because it can handle multiple mixed file/folder selections and it can create/verify SFV/MD5/SHA1 files. My writeup over at the Ars Forums goes into more detail.

CertUtil is a pre-installed Windows utility that can be used to generate hash checksums:

certUtil -hashfile pathToFileToCheck [HashAlgorithm]

HashAlgorithm choices: MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512

So for example, the following generates an MD5 checksum for the file C:\TEMP\MyDataFile.img:

  CertUtil -hashfile C:\TEMP\MyDataFile.img MD5

To get output similar to *Nix systems you can add some PowerShell magic:

$(CertUtil -hashfile C:\TEMP\MyDataFile.img MD5)[1] -replace " ",""

    Please note that certutil is not available in Windows PE, so if you are trying to calculate a checksum in a pre-deployment task script in PE, you will have to use an external tool like Microsoft FCIV.

    That's incredible, but CertUtil -hashfile C:\TEMP\MyDataFile.img MD5 does not produce the same hash than md5sum /tmp/MyDataFile.img under Linux (I guarranty it is the same file with a mount)

    Aug 16, 2016 at 9:22
  • 17
    @lalebarde There is only one standard for MD5. If you are getting different results on the same file, it is because something is making some change to that file and causing the hashes to be different. This is one of the most important functions of MD5 and other hashing standards.

    @mwfearnley, it looks like SHA1 is the default when the hash algorithm parameter is left unspecified, and that, when specified, the hash algorithm parameter is case-sensitive. So, I first tried certutil -hashfile ... sha1 and it failed. Then I left the ...sha1 off, and it worked. Then I retried with ...SHA1 and that worked. (And I repeated the test for md5/MD5.)

I'm using HashCheck (latest version) which integrates itself as a property page for files and includes a context menu to compare against hash check files (SFV).

It is free, and the source is available.

PowerShell version 4 and up includes the Get-FileHash cmdlet.

powershell get-filehash -algorithm md5 <file_to_check>

Use doskey to make a persistent alias that's easier to remember.

doskey sha1sum=powershell get-filehash -algorithm sha1 "$1"
doskey md5sum=powershell get-filehash -algorithm md5 "$1"

  • Brilliant question and answers. Thanks for all of this. I'd recommend another software, but this is pretty complete. Can't thank you contributors enough for this thread. Excuse me... May I ask why PowerShell on Win 8.1 and 10 won't recognize Get-FileHash "C:\foo.exe" -Algorithm MD5,SHA1,SHA256 | Format-List natively to list several hashes in a row? There's no such instruction stored in the console? I tried to reformulate several times with the correct syntax, but it returns me an error and it doesn't seem to work without embedding a script.

There is the FCIV utility from Microsoft, the Microsoft File Checksum Integrity Verifier (download link).

The Microsoft File Checksum Integrity Verifier tool is an unsupported command line utility that computes MD5 or SHA1 cryptographic hashes for files.

It doesn't show Windows 7 in system requirements but I've just used it in Windows 8 and it worked.

    That utility was useful for me. I downloaded an iso image from msdn and needed to cheksum it. I didn't want any third party tools. I didn't need the shell integration and the author didn't ask for it. It's from a trusted source Microsoft and while unsupported it still works. I posted a link here because other people like me may find it useful.

    While it's an OKish utility for moderate use, it's unstable. I'm using it in a xdelta script to determine if files of same size are different and I'm sorry to say I get about 1 crash every a few hundred files. It's unreliable, so an advice: use something else.

    FCIV hasn't been installed on any Windows system I've wanted to use it on, but certUtil was always there. I wish FCIV wasn't a top search result when I forget the name of the tool to use. I also wish this feature was just built in to the file properties dialog and browser download managers.

The new version of 7-Zip also gives you the option of checksums just by right clicking (this doesn't include MD5). It has SHA-1, SHA-256, CRC-32, CRC-64, etc.

Enter image description here.


For MD5 you can download HashTab and check by right clicking and then properties.

Here's one I've used before that integrates nicely with Explorer's "Properties" dialog: Summer Properties. It's open source, and an x64 version is also available.

I also like Safer Networking's FileAlyzer, which provides additional features as well. But just for checksums, Summer Properties is lightweight and does the job.

Nirsoft's HashMyFiles is small utility that allows you to calculate the MD5 and SHA1 hashes of one or more files in your system. You can easily copy the MD5/SHA1 hashes list into the clipboard, or save them into text/html/xml file.

HashMyFiles can also be launched from the context menu of Windows Explorer, and display the MD5/SHA1 hashes of the selected file or folder.

alt text

HashMyFiles is freeware and portable.

  • +1, Seems like a new one -- the last time I checked (before moving to a command line md5sum version) was FastSum -- but, it was sort-of trialware and nagged a lot. HashMyFiles is good because it allows drag-and-drop of multiple files and export to CSV (both important features). Don't think I had seen it when I found FastSum a couple of years back.

I am adding this here only because I didn't see any fully working powershell examples, ready for copy-paste:

C:\> powershell "Get-FileHash %systemroot%\system32\csrss.exe"

Algorithm       Hash
---------       ----
SHA256          CB41E9D0E8107AA9337DBD1C56F22461131AD0952A2472B4477E2649D16E...

C:\> powershell -c "(Get-FileHash -a MD5 '%systemroot%\system32\csrss.exe').Hash"

B2D3F07F5E8A13AF988A8B3C0A800880

C:\> CertUtil -hashfile "%systemroot%\system32\csrss.exe" MD5 | findstr -v file
b2 d3 f0 7f 5e 8a 13 af 98 8a 8b 3c 0a 80 08 80

C:\>

2019 Update:

The certutil output seems to have changed since Windows 8, so my old filter to isolate the hash doesn't work anymore. The extraneous spaces are gone too - one less thing to worry about when scripting. Here is the new copy-paste-able demo:

C:\>CertUtil -hashfile "%systemroot%\system32\csrss.exe" | findstr -v ash
0300c7833bfba831b67f9291097655cb162263fd

C:\>CertUtil -hashfile  "%systemroot%\system32\csrss.exe" SHA256 | findstr -v :
a37d616f86ae31c189a05b695571732073b9df97bf5a5c7a8ba73977ead3e65b

C:\>ver

Microsoft Windows [Version 10.0.16299.1451]

C:\>

To make this more resilient against breakage from yet another future change in certutil, we should look for lines with non-hex characters to filter out: [^0-9a-zA-Z]. That should also make it safer for other locales and languages.

C:\>CertUtil -hashfile  "C:\windows\fonts\arial.ttf" | findstr -vrc:"[^0123-9aAb-Cd-EfF ]"
12c542ef8c99cf3895ad069d31843a5210857fdc

Why is that actual anti-hex regex so weird ? See this question to learn how regex ranges in findstr don't work as they should. I included an extra space character for backward-compatibility with older certutil versions, but it is optional.

Note that the powershell Get-FileHash default is SHA256, while certutil still defaults to SHA1. So specify your algorithm explicitly where needed. You can quickly check the available options like this:

C:\>powershell -c "Get-FileHash -?" | findstr gori

    Get-FileHash [-Path] <string[]> [-Algorithm {SHA1 | SHA256 | SHA384 | SHA512 | MACTripleDES | MD5 | RIPEMD160}]
    Get-FileHash -LiteralPath <string[]> [-Algorithm {SHA1 | SHA256 | SHA384 | SHA512 | MACTripleDES | MD5 |
    Get-FileHash -InputStream <Stream> [-Algorithm {SHA1 | SHA256 | SHA384 | SHA512 | MACTripleDES | MD5 | RIPEMD160}]

C:\>certutil -hashfile -v /? | findstr gori

  CertUtil [Options] -hashfile InFile [HashAlgorithm]
Hash algorithms: MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512
14

I found this PowerShell script:

param([switch]$csv, [switch]$recurse)

[Reflection.Assembly]::LoadWithPartialName("System.Security") | out-null
$sha1 = new-Object System.Security.Cryptography.SHA1Managed
$pathLength = (get-location).Path.Length + 1

$args | %{
    if ($recurse) {
        $files = get-childitem -recurse -include $_
    }
    else {
        $files = get-childitem -include $_
    }

    if ($files.Count -gt 0) {
        $files | %{
            $filename = $_.FullName
            $filenameDisplay = $filename.Substring($pathLength)

            if ($csv) {
                write-host -NoNewLine ($filenameDisplay + ",")
            } else {
                write-host $filenameDisplay
            }

            $file = [System.IO.File]::Open($filename, "open", "read")
            $sha1.ComputeHash($file) | %{
                write-host -NoNewLine $_.ToString("x2")
            }
            $file.Dispose()

            write-host
            if ($csv -eq $false) {
                write-host
            }
        }
    }
}

Microsoft File Checksum Integrity Verifier. It can compute MD5 and SHA-1 hash values.

Download, extract the files, then open a command prompt, go to the extracted path and then type the following command:

fciv -md5 filepath\filename.extension

A batch file based on pbarney's comment to the answer with the most upvotes: This copies the MD5 hash of whatever file is dragged onto the batch file to the clipboard:

@ECHO OFF
FOR /f "tokens=*" %%i IN ('@certutil -hashfile %1 MD5 ^| find /v "hash of file" ^| find /v "CertUtil"') DO SET r=%%i
SET r=%r: =%
ECHO %r% | clip

To make it a context menu item instead:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\*\shell\Get MD5]
@="Copy MD5 to Clipboard"

[HKEY_CLASSES_ROOT\*\shell\Get MD5\command]
@="\"C:\\<PATH TO BAT FILE>\\getMD5.bat\" \"%1\""

  • Or if you don't mind the extra output, a one liner batch file certutil -hashfile %1 md5 works as well

MD5 Context Menu does exactly this. It adds an MD5 option to the context menu of files:

Enter image description here

MD5 Context Menu is a freeware shell extension for Windows which displays the MD5 hash sum of the selected file.

It says it's compatible with Windows 95, 98, ME, NT, 2000, and XP, although it works for me perfectly fine on Windows 7. It's a tiny download (238 KB) and includes everything you need.

This is just a cmd shell script which uses tedr2's answer but strips off the extraneous output lines and spaces:

:: hash.cmd : Get a hash of a file
:: p1: file to be hashed
:: p2: Hash algorithm in UPPERCASE
:: p3: Output file

@setlocal
@for /f "tokens=*" %%a in (
'@certutil -hashfile %1 %2 ^|find /v "hash of file" ^|find /v "CertUtil"'
) do @(
  @set str=%%a
)
@set str=%str: =%
@echo %str%
@endlocal

The output can be re-directed to a file if required:

@echo %str% > %3

e.g.

sys> \dev\cmd\hash.cmd MyApp.dll SHA1
8ae6ac1e90ccee52cee5c8bf5c2445d6a92c0d4f
2

The correct answer is of course, yes, CertUtil (see tedr2's answer).

But I'll add Penteract's free File Checksum Verifier which, I think, is one of the most user-friendly programs. (Disclaimer: I'm affiliated with Penteract.)

Some of its advantages:

  • Compares the calculated and expected hashes for you.
  • Minimalistic - no item in files' context-menus, no extra tab on files' properties.

To verify this program's integrity (against man-in-the-middle attacks) - it downloads over a secure connection.

Penteract File Checksum Verifier

Plus: free, offline (so you don't have to upload your files), user-friendly (drag a file in and get the result), launches from the start menu (no need to look for the downloaded executable when you want to use it a year from now), and supports MD5, SHA1, SHA256, etc.

1. checksum

I use checksum command-line utility.

Usage:

checksum [-t=sha1|sha256|sha512|md5] [-c=signature] [-f=]filepath


2. Command-line arguments

  • -?, --help, -h
    Prints out the options.
  • -f, --file=VALUE
    Filename.
  • -t, --type, --hashtype=VALUE
    Hashtype Defaults to md5.
  • -c, --check=VALUE
    Optional: check - the signature you want to check. Not case sensitive.

3. Examples of usage

# Check md5 for "E:\Саша Неотразима\Sasha-Irresistible.exe" file
SashaChernykh@DESKTOP-0G54NVG E:\Саша Неотразима
$ checksum -f "E:\Саша Неотразима\Sasha-Irresistible.exe"

Something like this: winmd5sum.
This one's also nice: sendtoMD5 - right click, send to ..., and it gets you the result.

HashTab 3.0 is a free shell extension that calculates many checksums, including MD5. It's integrated as a new tab in the File Properties.

You can use MD5sums for Windows, a download of only 28 KB (Cygwin might be overkill if all you want to do is compute MD5 hashes).

The easiest way to use it is to use Explorer to drag and drop files on md5sums.exe to obtain their MD5 hashes.

This is not a built-in utility, but its a very good option

http://checksumcompare.sanktuaire.com

You could compare checksum by file and/or summaries if two folders differ or are identical.

You can try msys2, it is here.

Just type (algorithm)sum. (algorithm) is the hash algorithm you want to use e.g. md5, sha1, sha256 ...

Unlike Cygwin, this tool is portable, you just to download the .zip file and extract in anywhere you want. You can use it by a simple click(msys2.exe).

Hop this tool will help you.

OpenHashTab is open source, integrates with Explorer, and is actively developed.

It's a good alternative to HashCheck, as that one isn't maintained any more (for over 6 years).

If you don't have time to check output from certutil character by character <hash size> number of times, pipe to find utility to see if checksum matches:

certutil -hashfile ekaf_elbatuc.exe sha256 | find "<checksum>" && echo File ok. || echo Some mole or rat waz hia

But then what's the point of getting hash from same server as the file itself?

This is how I calculate checksums from Explorer using no third-party software.

On Windows 10 (and probably previous versions) follow these steps:

Using explorer, open the "Send To" folder by typing this into the address bar

shell:sendto

Create a batch file in this folder called something like Calculate SHA1 and MD5.cmd

and add this text

@echo off
certUtil -hashfile %1 SHA1
certUtil -hashfile %1 MD5
pause

You will now be able to calculate SHA1 and MD5 checksums for any file from Explorer, just by right-clicking a file and choosing send to Calculate SHA1 and MD5.cmd

Off course, you can change the name of the above file and choose to add other checksums, or even create multiple files each with a different type of hash.

I have another batch file called Calculate SHA256.cmd, which I prefer to use independently (you wouldn't want to calculate every type of hash from one batch file as this would take too long for very big files).

Some more notes

Just to make the output a little less cluttered, I prefer to pipe the output through findstr.

certUtil -hashfile %1 SHA256 | findstr ^1

The pause instruction at the end of the batch file is essential, otherwise the window will disappear immediately.

Well, I have made a program to calculate some hashes from a file. I hope it helps you.

What does this do? It calculates the SHA-1 hash, SHA-384 hash, MD5 hash and SHA-256 hash. Well, that's about it :)

There are like 100 third-party tools out there. I use MD5Hash. For downloads with sfv files, just use TeraCopy to verify the hashes.

For a solution that works on Windows or just about any other environment, use Python.

  1. install Python -- a Windows installer is provided on https://www.python.org/downloads/

  2. download a tested cksum implementation, e.g. http://pastebin.com/raw.php?i=cKATyGLb -- save the contents of this to say, c:\cksum.py or wherever you find convenient

Then to perform a checksum:

python c:\cksum.py INPUTFILE

Not as fast as a compiled utility, but compatible with Unix cksum and runs anywhere.
