Hashtab what is this program and how does it work

What is the hash sum of a file

Everything is very, very simple with this very hash - let's take two files that, at first glance, are exactly the same...

Let's say that I downloaded them from different sites. As you can see, they have exactly the same name and extension, but besides this similarity, these installers may have a similar size down to the last byte.

Ordinary ordinary users do not even realize that such “exe files” are practically simple archives.

So, it’s very easy to slip some kind of malware (virus) into this file (archive) - they almost always disguise themselves as the “correct” file, copying not only the name and extension, but even the size.

Such a modified file can be distributed on the Internet under the guise of being official, white and fluffy.

By the way, there is no perfect antivirus and your Defender can fail at any time, if you didn’t know.

Another situation - have you chosen and started downloading any program, file or archive via torrent? In this case, it’s even easier to slip in a little stray virus, because the file is downloaded into the computer in tiny parts, from a huge number of people, and is collected into a pile only by the end user.

When to install the program.

The service is installed when the user notices that his PC has become slower. When difficulties arise when accessing any sites on the Internet, it is also necessary to use this service.

It will quickly and without any additional actions be able to detect dangerous viruses that infect the computer and prevent its normal operation.

Spyware-infected files will also open. By understanding hashtab what kind of program it is, you will greatly facilitate and speed up the work of your PC.

Quite often, a user needs to find damaged files on a computer. In order to find these files, there are many programs and one of them is Hashtab. It is a Windows Explorer extension and a Mac Finder plugin. Using this program allows the user to forget about problems with installing some files and images. Hashtab finds all missing file fragments and reports them to the user, and also protects the computer from malware and viruses.

Algorithms (standards) for calculating the hash amount of a file

There are quite a lot of them at the moment...

1. Adler-32
2. BTIH (BitTorrent Info Hash)
3. CRC32
4. eDonkey2000
5. GOST (GOST R 34.11-94)
6. MD5, MD4, MD2
7. RIPEMD-128, RIPEMD-256, RIPEMD-320
8. SHA-1
9. SHA-2 (SHA-256, SHA-384, SHA-512)
10. SHA-3 (SHA3-224, SHA3-256, SHA3-384, SHA3-512)
11. TTH (Tiger Tree Hash)
12. Tiger
13. Whirlpool
14. …

...but the most common and popular are...

I recommend

• SHA-1
• MD5
• CRC

Hash sums of one file created according to different standards will differ from each other very noticeably (not compatible for verification)…

• CRC: 02668A079

• SHA-1: F77EB9AA67CE63EDC87B77BF35DFEB9AA63E9B4C

• MD5: 00EF4D6A8122DDE85BDBC7ED3A1362

Today we will not discuss or study how to create (set) the hash amount of a file - this will be the topic of the next article.

Data and disks ⇒ HashTab 6.0.0.34 Commercial

Digitally signed version dated December 6, 2017
HashTab
is a Windows Explorer extension for verifying the integrity and authenticity of files by calculating a checksum. HashTab supports many hashing algorithms such as CRC, MD5, SHA1, SHA2, SHA3/Keccak, RipeMD and Whirlpool, as well as BitTorrent Info Hash and Magnet link generation.

After installing HashTab, right-click on any file. On Windows, select Properties and you will see a new tab called File Hash Sums.

With HashTab

You can hash other files for comparison in order to check the checksum and find out whether it matches the one specified by the releaser in his distribution. To do this, just drag the file or paste the hash text into a special panel, you can also use the “Compare file...” function. and search to find the required file; if the amount matches, there will be a green checkmark, so you don’t have to compare MD5 hashes with your eyes.

By clicking on one of the checksums we can:

• Copy all amounts • Copy a specific amount using a specific algorithm • Configure which hashes will be calculated and displayed.

Full list

HashTab supported hashing algorithms for checksum calculation: • Adler-32 • CRC32 • GOST (GOST R 34.11-94) • MD5, MD4, MD2 • RIPEMD-128, RIPEMD-256, RIPEMD-320 • SHA-1 • SHA-2 (SHA-256, SHA-384, SHA-512) • Tiger • Whirlpool

How to check the hash of a file - HashTab

Very, very simple. Now we will install a special tool in Windows Explorer to calculate and verify this file checksum.

A completely free computer program called HashTab will help us.

We install it into our operating system (the link to download the installer is just below)…

...and we get an additional tab in the properties of any file...

I decided to check the hash sum of a large file and therefore, as you can see above, I even managed to take a screenshot. With files of regular, medium size, this procedure occurs almost instantly...

A green checkmark in the “Hash Comparison” section that appears means that everything is fine and the file was teleported safe and sound (no one intercepted it along the way or introduced a virus into it).

You can simply find out the amount of the file or compare it with the original source (for example, from the manufacturer’s website of a downloaded program). To do this, simply insert it into the line and press the “Compare file...” button.

HashTab settings are very simple and boil down to activating (displaying) additional standards in the file properties window...

HashTab - checksum verification

Share

The article describes and demonstrates in detail the installation, configuration and procedure for checking the checksum (hash sum) of a file using the HashTab program.

Checksum (hash sum) is a specific value calculated for data using known algorithms. Intended to confirm the integrity and authenticity of the transmitted data.

By comparing the checksums of an image or file, you can immediately find out whether this file has been modified or not (if the checksum does not match the required one, this means that the file has been modified). Comparing checksums is especially important before installing operating systems and other software.

The user will see many different sum indicators. If they do not match, you can understand that the file is either damaged or infected with malware. All values ​​of the file selected by the user are immediately displayed in the corresponding field. You can sort them by type and select the one you need. To make work easier, the creators of the program have built libraries into it in DLL format. You can place the text of the hash value in the work field, which will make it possible to compare the hash in an instant. A pointer in the program will point out all differences and similarities in values ​​without any visual comparison.
