Whenever you download files from the internet, pretty often you cannot be completely rest assured that the files haven't been modified in some way from its original state either by the site you are downloading from, or corruption due to errors during the download process, third party, or the most feared – that the file has been infected by malicious software! One of the ways through which you can confirm whether or not a file has been changed from its original state is to check its digital signature if (it has one). Or you can crosscheck the file's integrity by examining its hash value. The trick here is that every file has its own unique data contained in it – when you apply a certain algorithm called a "cryptographic hash function" to it, it will return a string value (which is only valid for that file in that current state) – If any section of data in the file is modified, even by 1 byte, and you reapply the algorithm, the returned value this time will be different from the previous value – now, using the information that has been generated, you can see whether the file is original or not, or if it has been modified (in the case of this example, the file has been modified).

MD5 & SHA Checksum Utility is a tool that allows you to verify/confirm the integrity of a file by helping you find out its MD5, SHA-1, SHA-256, and SHA-512 signatures, respectively. The application is simple, smart, and lightweight such that inexperienced users can easily handle the software without stress. Results gotten from the verification process are usually accurate and straightforward, making this checksum utility tool a very efficient and reliable.

How Can MD5 & SHA Checksum Utility Tool Help You Quickly and Easily Verify the Originality Of Your Downloaded File?

The first admirable quality of this application is the fact that it is so lightweight that and portable such that you may not even need to install it. This means that you can simply carry the app on your USB flash drive or similar storage unit, and run it on any computer on the fly, or you may install it if you prefer to. The application also features a simple and smart interface that is quite simple to figure out. All the options are outlined on the main window. Also, you can open a file by using either the file browser method or the "drag and drop" method; either way, the MD5, SHA-1, SHA-256, and SHA-512 checksums are all automatically displayed on your screen, and you can then copy either of them or the entire text to the Clipboard. Additionally, you can insert another hash, if you want to compare it to the files. Also, because the entire program is very lightweight, it doesn't disrupt the CPU overall performance as it also uses very small system resources. 

This application also has a good response time so that it instantly calculates the hashes, allowing for a smooth-running without glitches. Also, this program works fine with a wide range of operating systems and devices, including Windows XP, Windows Vista, Windows 7…, etc., Mac and Linux.

It is also important to note that this program is written in Powershell; therefore, no external programs are installed on it. Also, you can calculate more than one file at a time.

Key Features of MD5 & SHA Checksum Utility Tool Include:

  • Simple and smart user interface.
  • Ability to run quick checksum verifications.
  • Compatibility across several devices and platforms.
  • Ability to calculate more than one checksum at a time.
  • Application is portable.
  • Minimal system requirements on all devices.

  • The application uses minimal system resources.
  • Application is free.


This application is a great utility tool for checking and verifying file checksums. It offers quick analysis and accurate results. Also, the software is very portable, so you can have it with you on the fly. It also allows you to calculate multiple checksums at a time while using very little system resources. The application is generally easy to use both for rookies and newbies, respectively.
