There are different ways to calculate a checksum, and they can be as simple or as complex as needed. If the values don't match, it indicates that the data has been altered in some way, intentionally or unintentionally.

If the two values match, the data is assumed to be error-free.

When the data set is to be retrieved or received, the checksum value is recalculated and compared with the original one.

When a data set is sent or stored, a checksum value is calculated, sent, or stored along with the data.

It is a simple yet reliable method of detecting errors during data transmission or storage. It's usually applied to large amounts of data, such as a file or an entire website.Ī checksum is a value computed from a data set, often a file, and is used to verify the integrity of the data. What Are Checksums?Ī checksum is a mathematical formula that's used to verify whether something is correct or not. They're also helpful in providing that someone else hasn't altered the data you've entered into a form. This article will explain everything you need to know about them.Ĭhecksums are used in many different situations, from verifying that an email has been sent correctly to ensuring that files on your computer haven't been corrupted.
