Hash FunctionAn algorithm that computes a hash value or checksum from any set of data, like a file. Common hash functions include MD5 and SHA1. Hash functions are used to check file integrity and for security purposes.

Integrity
The quality of being whole, unaltered, and uncorrupted. A file that is not intact may not be usable or may have decreased informational and evidential value. Videos files can lose their integrity if they are accidentally mishandled, deliberately tampered with, or if data corruption occurs in transfer or storage due to hardware or software malfunction. The best way to ensure integrity is to establish a system to check file fixity regularly (e.g. by computing hashes and checking them against a registry of previously computed hashes) and to restore any corrupted files from an intact copy.
Hash ValueThe string of alphanumeric characters that results from running a hash function algorithm on data or a file. The hash value of a file will always remain the same as long as the file is unchanged, so it can be used to identify altered, corrupted, and duplicated files.
