Hash

definition A hash function is any function that can be used to map data of arbitrary size to fixed-size values. The values returned by a hash function are called hash values, hash codes, digests, or simply hashes --- Wikipedia

properties

hash functions are often optimized so as to minimize hash› collisions

hash functions are deterministic

applications

hash functions are used in cryptography

Hash Collision

definition a hash collision is a situation in which two different inputs are mapped to the same hash value --- GitHub Copilot
