WebJul 29, 2024 · A hash is a small set of data that is mathematically tied to some larger set of data from which the hash is calculated. If the larger set of data is changed, the hash also changes. Hashes are useful, for example, as a checksum to verify that data has not been modified in transmission. A cryptographic hash is a hash that fulfills certain properties.
