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:TEMPMyDataFile.img:

  CertUtil -hashfile C:TEMPMyDataFile.img MD5

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

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

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.

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.

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"

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.

.

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.

HashMyFiles is freeware and portable.

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

            }

        }

    }

}

It leverages .NET which I assume you have installed

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%system32csrss.exe"

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 filepathfilename.extension

For example:

fciv -md5 d:programssetup.exe

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*shellGet MD5]

@="Copy MD5 to Clipboard"



[HKEY_CLASSES_ROOT*shellGet MD5command]

@=""C:\<PATH TO BAT FILE>\getMD5.bat" "%1""

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:

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> devcmdhash.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.

• 
  Open source,


• Support md5, sha1, sha256 and sha512.

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 НеотразимаSasha-Irresistible.exe" file

SashaChernykh@DESKTOP-0G54NVG E:Саша Неотразима

$ checksum -f "E:Саша НеотразимаSasha-Irresistible.exe"

342B45537C9F472B93A4A0C5997A6F52

# Check sha256

SashaChernykh@DESKTOP-0G54NVG E:Саша Неотразима

$ checksum -f "E:Саша НеотразимаSasha-Irresistible.exe" -t=sha256

F6286F50925C6CBF6CBDC7B9582BFF833D0808C04283DE98062404A359E2ECC4

# Correct 41474147414741474147 sha256 hash or not?

SashaChernykh@DESKTOP-0G54NVG E:Саша Неотразима

$ checksum -f "E:Саша НеотразимаSasha-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 НеотразимаSasha-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.

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.
