Cryptographic Hash

Primary definition

A cryptographic algorithm that computes a numerical hash value based on a data file or electronic message. It should be infeasible in practice to find two distinct data files or messages that will result in the same numerical hash value. The numerical value can be considered to be a fingerprint of the file or message. Colloquially known as a hash, hash function, or digital fingerprint. Hashes provide integrity protection.
