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. – Phoshi Feb 14 '11 at 19:03

    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. – afrazier Feb 14 '11 at 19:14

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. – afrazier Feb 14 '11 at 21:51

    Be aware HashTab is only free for private use! HashCheck is open source and complete free (BSD license) – keiki Oct 22 '12 at 14:08

    > "Thanks. Unfortunately being built-in was an essential requirement for me." Then why did you select a non-built in software, which the question doesn't ask for, as the answer? – KalEl Sep 10 '17 at 20:14

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 " ",""

    The question specified built-in, and aside from a powershell script, this is the only one that is built in to Windows 7. There are some environments where you can't just install software. My single upvote doesn't seem like enough for this answer. – jbo5112 Sep 23 '15 at 14:30

    MD5.bat: @certutil -hashfile %1 MD5|find /v "hash of file"|find /v "CertUtil" – pbarney Nov 16 '15 at 15:37
  • 5
    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. – Wayfarer May 19 '16 at 8:14
  • 3
    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) – lalebarde Aug 16 '16 at 9:22
  • 9
    @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. – Paul Oct 19 '16 at 16:27

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.

    Hilarious app. Definitely the best. It can check the hash with a doubleclick on the created file.MD5! And it remembers what files were hashed. – Pavel Radzivilovsky Dec 23 '10 at 14:26

    @Sossenbinder You must have been looking in the wrong place. SHA-256 has been supported since Dec. '14.

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.

  • Why are we linking to a unsupported command line utility. This doesn't even intergrate into the shell which I am sure the author wanted. – Ramhound Sep 5 '12 at 12:36
  • 30
    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. – creator Sep 6 '12 at 4:25
  • 28
    I'm with @creator. It may not be supported software, but at least Microsoft is the author. Checksum programs are potentially really important to maintaining security; I'd rather not get mine from some random third-party. – ellisbben Sep 18 '12 at 18:00

    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. – JasonXA Mar 5 '17 at 17:58

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. – K0media Feb 14 at 17:08

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.

Enter image description here

  • Which version of 7-zip are you talking about? – klaar Aug 15 '17 at 13:06
  • Unfortunately, the 7-zip checksum tool doesn't allow you to copy the checksum! – Derek Mahar Dec 5 '17 at 15:59
  • I think selecting the hash text and Ctrl+C works fine. – abe312 Dec 6 '17 at 16:22
  • In my setup, if you go to properties of the file, you can copy the hash via right click->copy under file hashes tab. – abe312 Dec 23 '17 at 5:46

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.

SummerProperties screen shot

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.

    Another problem with it is that you can't paste an hash into it and see if it matches – Jonathan Mar 23 '11 at 16:33

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. – nik Dec 30 '09 at 2:15

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

            } else {

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

  • This answer and @creator's answer should be combined. They refer to the same tool. – leif81 Jun 11 '14 at 13:36
  • Question Title : Is there a built-in checksum/hash utility on Windows 7? 'fciv' is not recognized as an internal or external command, operable program or batch file. Microsoft Windows [Version 10.0.14393] – Amit Naidu Jul 9 at 19:24

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 – jrh Aug 20 at 14:21

Unfortunately, not that I'm aware of, but Microsoft's Sysinternals suite includes a nice tool called sigcheck.

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

Cygwin contains an md5sum.exe utility that should do what you want.

QuickHash supports SHA-256 and SHA-512. I needed SHA-256 support to verify the checksum of whitelisted JavaScript libraries for inclusion in a Firefox addon.

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"
342B45537C9F472B93A4A0C5997A6F52
# Check sha256
SashaChernykh@DESKTOP-0G54NVG E:\Саша Неотразима
$ checksum -f "E:\Саша Неотразима\Sasha-Irresistible.exe" -t=sha256
F6286F50925C6CBF6CBDC7B9582BFF833D0808C04283DE98062404A359E2ECC4
# Correct 41474147414741474147 sha256 hash or not?
SashaChernykh@DESKTOP-0G54NVG E:\Саша Неотразима
$ checksum -f "E:\Саша Неотразима\Sasha-Irresistible.exe" -t=sha256 -c 41474147414741474147
Error - hashes do not match. Actual value was 'F6286F50925C6CBF6CBDC7B9582BFF833D0808C04283DE98062404A359E2ECC4'
# One more attempt
SashaChernykh@DESKTOP-0G54NVG E:\Саша Неотразима
$ checksum -f "E:\Саша Неотразима\Sasha-Irresistible.exe" -t=sha256 -c F6286F50925C6CBF6CBDC7B9582BFF833D0808C04283DE98062404A359E2ECC4
Hashes match..

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.

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.

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.

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.

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.

I like digestIT, although it seems to be fairly old and maybe not maintained.
