What is Checksum Checker?
“Checksum Checker” is a free online tool that lets you calculate the checksum of your files. You can choose multiple files with it and calculate the checksum of all the chosen files in one go. It can also be handy if you want to compare the checksums of different instances of the same file to make sure the integrity of the file.
Currently, the tool uses MD5 hash to calculate the checksum. We will soon be adding more methods.
You might still be confused if you don’t know about checksum, so you might want to say that the question is:
What is Checksum?
To understand it easily, checksum can be considered as a fingerprint of something. It can be used to make the thing (data/file in our case) hasn’t changed at all. Technically, checksum is the result of a combination of some formulae applied on the data or file content. The result is always the same if the provided data/content is same. And the result is different when the data/content provided is different.
The checksum can be used to verify the data/content has not been modified or tempered. Therefore, it makes it very easily to verify file integrity for security.
