WebVerifying a file's fixity is typically accomplished by generating, recording, and monitoring a checksum. Running a checksum is process that maps data to a bit string of a fixed size in the form of a cryptographic hash.This hash is stored and compared during file movements and can be used to verify the integrity of files in a storage environment.
