In Windows you can make a checksum of a file without installing any additional software.
For this you can use the certUtil – built-in command-line tool that works both in Windows CMD and PowerShell.
In this note i will show the examples of how to make md5sum and sha256sum of a file in Windows from the command line.
Cool Tip: zip and unzip from the command line in Windows! Read more →
Checksum a file in Windows using the built-in certUtil command-line utility:
C:\> certUtil -hashfile <PATH_TO_FILE> <HASH_ALGORITHM>
MD5 checksum example (md5sum):
C:\> certUtil -hashfile C:\file.img MD5
SHA256 checksum example (sha256sum):
C:\> certUtil -hashfile C:\file.img SHA256
Get only hash value:
# Windows CMD: C:\> CertUtil -hashfile C:\file.img MD5 | findstr /v "hash" # Windows PowerShell: PS C:\> $(CertUtil -hashfile C:\file.img MD5)[1] -replace " ",""
Available hash algorithms:
MD2 MD4 MD5 SHA1 SHA256 SHA384 SHA512
Hash Algorithms: Note that on Windows 7, the hash algorithms are case-sensitive. Be sure to type, for example, not “md5” but “MD5”. In the subsequent versions of Windows the case doesn’t matter.

MD5Sum is a type of software that is used for either a Mac or Windows on a computer to verify the security of the files. If a file has been changed, whether that is a result of a error in the disk, this software will detect it. MD5Sum is like a security guard who
chevks that all the files are still in tact and they are fully secure and do not contain an errors or anything else that may cause a virus in the computer. Specific steps are found on how to download this software either on Windows or on a Mac computer. All one has to do is open their Windows, for example, and type in CMD by pressig their Start menu first. Then, one types in Cerritos when they see the blinking cursor on the computer screen. After that is typed in, type a space and type in hash file then another space after and drag and drop your file of choice into the command prompt. The last step is to type in check MD5Sum and that will be created. It is as simple as that. Afterwards, one can continue this process with various files to make sure they are all secure. If not, they can be deleted or changed or create a new and different file. MD5SUM is a great way to check the security (integrity) of files in your computer and take the necessary actions when needed. It is not a difficult task and will also verify if they are any errors in any of the files as well.
Features:
This type of software is used to check if the files contain any errors and level of security

MD5Sum is a software that calculates and verifies the MD5 hash value of a file, which is a unique digital fingerprint of its content. It is a command-line tool that works on various operating systems and is often used for data integrity checks, file comparison, and security purposes. Its main features include generating MD5 checksums for files, comparing checksums with other files, and verifying the integrity of downloaded files. It can also be used to detect file tampering or corruption, and to ensure that the transferred files have not been altered during transmission.

Знаток про MD5 Checksum Tool 3.9.0.0 [25-02-2018]
Из комментариев с других сайтов, считается, что это программа очень медленная, из-за того, что вычисляет дополнительно три параметра SHA256, SHA384, SHA512, которые, кстати, на практике почти не используются.

The md5sum utility is used to calculate what is called the fingerprint of a file. A small tutorial for the program «md5» or «md5sum» commonly called «checksum». (The checksum is a value of 128 bits corresponding to a checksum calculated from the archive).
What is a MD5 checksum?
An MD5 checksum is a cryptographic hash function that is used to generate a fixed length alphanumeric string representing input data. It is often used to verify the integrity of a file during transfers or downloads by detecting minor changes in the input. It is not secure enough for cryptographic purposes, or vulnerabilities. This is why there is a preference for more secure hash functions, such as SHA-256 or SHA-3.
How to do a MD5 checksum in Windows?
Using Command Line
First download md5sum for Windows
- Unpack the archive into a folder at the root of ‘C’. In our example, we will name «md5sum».
- Open a console MSDos.
- Start > Run.
- Type cmd (W2K or XP) or command (on Win98) and press [Enter] on your keyboard.
- Change to the directory containing the»md5.exe» file in the command line.
C:\> cd md5sum [Enter]
If however, you were not at the root of your hard drive, type: cd then [Enter].
C:\md5sum>
Make sure the «md5.exe» file is there:
C:\md5sum>dir /w /p [Enter]
[.] [..] index.html main.c
md5.c md5.exe md5.gif md5.h
md5.vcproj rfc1321.html rfc1321.txt
11 file(s) 157 564 bits
2 Dir(s) 6 791 827 456 bits libres
Then run the following command:
md5 'The_complete_path_to_your_Iso_image' [Enter]
Example: Assuming that our image file is in «D: \ image_isoSmoothwall»
C:\md5sum>md5 D:\image_isoSmoothwall\smoothwall-2.0-metro.iso [Enter]
After a few seconds you should have the following result:
D0AB11311B866B2332E92479906F2FF9 D:\Linuximage_isoSmoothwall\smoothwall-2.0-metro.iso
Use the «-n» if you do not want to have the name and path of the image displayed after the comparison: C:\md5sum>md5 -n D:\image_isoSmoothwall\smoothwall-2.0-metro.iso [Enter]
D0AB11311B866B2332E92479906F2FF9
You just have to compare the result obtained with the «md5.txt» file, or «iso.md5 …» or even «… iso.md5.asc», downloaded along with your «iso» image.
Another method is to place the program «md5» or «md5sum» (depending on the program downloaded) in one of the following directory:
- C:\windows\command\ (for Windows 95/98/Me)
- C:\winnt\system32\(for Windows 2000)
- C:\windows\system32\ (for Windows XP, Vista et 7)
You can from this point call the «md5» or «md5sum» command (from the MSDos command prompt) directly from the directory containing the .iso image.
Example: D:\image_isoSmoothwall>md5 -n smoothwall-2.0-metro.iso [Enter]

Via a Graphical User Interface «GUI»
MST MD5
Download MST MD5
Once installed, launch it, a small GUI will open prompting you to:
«Simply drag the file on this window to see the MD5 checksum»
That’s it. You have nothing else to do but wait (less than a minute at most, depending on the size of the file).
WinMD5
Download WinMD5
- Select the file to be checked,
- Click on [Calculate]
- Copy the key that was provided into the comparison field.
- Click [Compare] to compare the different values.
- The result is displayed in a window confirming the authenticity of the file scanned.
How to do a MD5 checksum in GNU/Linux?
In Console Mode
The md5sum usually comes (by default) with most distribution. If, however, it is not present, refer to the following address to download a compressed archive:
- http://www.fourmilab.ch/md5/
Under GNU/Linux, all you have to do is to go to the directory containing your file to verify and type the following command:
-
$md5sum filename [Enter].
The result should appear after a few seconds as follows (same as in Windows):
-
D0AB11311B866B2332E92479906F2FF9 filename
If you don’t want to go to the directory containing the file to be checked, you can also specify a path like this:
-
$md5sum /home/user/download/filename [Enter]
Note that: Remember to use the «completion» (press the TAB key) to complete your command lines.
Via a Graphical User Interface
There is a project called Parano offering a GUI for the creation/editing/checking MD5 or SHA-1 under Gnome.
The project seems to be discontinued, but still it may be helpful
How to generate a MD5 checksum?
For Windows and GNU/Linux
To generate an MD5 sum, you must simply perform the same operation as the verification, namely:
md5sum filename [Enter]
Note: The filename can be any type of file (archive, images, text, iso, executable, etc.. etc..).
On Windows, the command is not always present natively.
If you want to create a text file (my_file_md5sum.txt), you must redirect the output of the md5sum command to the text file itself instead of standard output, namely the screen. Use the redirector «>», common to Windows and GNU/Linux.
filename md5sum> my_file_md5sum.txt [Enter]
