Checksum
A
checksum or
hash sum is a small-size datum from a block of
digital data for the purpose of
detecting errors which may have been introduced during its
transmission or
storage. It is usually applied to an installation file after it is received from the download server. By themselves checksums are often used to verify data integrity, but should not be relied upon to also verify data
authenticity.
