The idea behind it is to calculate file hashes and checksums and then compare their contents using a specialized algorithm. The tool will generate a checksum file, and from what we’ve gathered ...

If the checksum of two files is the same, we can easily confidently say that both files are the same. Many algorithms are used to calculate the checksum, and the one we are talking about here is MD5.

But how do you calculate the MD5 hash value of a file you've downloaded when you're running a Windows-based PC? Microsoft provides a free but unsupported command-line utility called File Checksum ...

For any file you may have or create, you can trivially calculate its MD5 checksum on your PC, Mac, or another device. And, the slightest change to the file's contents even by a character or pixel ...
