Calculating a file’s checksum is a fast way to ensure whether its integrity has been modified - sometimes, tampering with a file can suggest that it has been infected by malware, so it is best to compare checksums before opening the file, not afterwards.
MD5 Checker is one of the applications that comes in handy when you want to quickly calculate the hash value of any file, especially since the utility does not need to be installed onto the host computer.
Its graphic interface is intuitive and user-friendly, so that even those who are not computer experts can use its functions without any issues.
First of all you need to drag and drop any file on your computer over the main window of MD5 Checker so that it instantly displays several types of checksums, so you can choose the one you are interested in. If you selected a very large file, the process might take a little longer, but the results are still shown within the main window.
In addition to displaying the exact size of the file, MD5 Checker also calculates various types of checksums, so you get the MD5, SHA1, SHA512, SHA256 or SHA284.
You can copy any of these values with a single mouse click, which makes it easy for you to paste the string in another app and compare the values. This is useful when you want to assess the integrity of downloaded files, so you compare the checksum provided by the developer with the one generated by MD5 Checker - if they are identical, it means the file is safe, but if they differ, the download file might have been infected so it should not be opened.
All in all, MD5 Checker is reliable software solution and it should be used whenever you suspect foul play with your downloaded files.
