WebbA checksum is a calculated value using a cryptographic hash function to verify the integrity of data, such as a binary file. Checksums are mostly used for comparing between the source of a file and a copy of it to ensure that the copy is identical to the source. A checksum is a small-sized block of data derived from another block of digital data for the purpose of detecting errors that may have been introduced during its transmission or storage. By themselves, checksums are often used to verify data integrity but are not relied upon to verify data authenticity.

Webbchecksum: A checksum is a count of the number of bits in a transmission unit that is included with the unit so that the receiver can check to see whether the same number of bits arrived.
