Checksum is a file management application and software that is used to verify the integrity of data stored in a file. It is used to check whether the data stored in a file has been modified or not. It works by calculating a numerical value, called a checksum, based on the contents of a file, which is then compared to a reference value stored elsewhere. If the two values match, then the data stored in the file is assumed to be unmodified. Checksum is widely used in software distribution, digital signing, and file integrity checking. It ensures that the files have not been tampered with or corrupted, and that the data is intact.
