WebA checksum is like a digital fingerprint of a file or code. It’s a calculated value made of numbers and letters used to verify the integrity of a file. One of the most common uses of checksums is confirming whether a downloaded file is corrupted or has been tampered with since it was originally created. How? This is what you’re going to learn next.

WebA checksum is a number. It is a kind of redundancy check. There are different ways to calculate it. It serves as a check, that no errors have been made when writing down the number.
