WebA hash function is a mathematical function that converts a numerical input value into another compressed numerical value. The input to the hash function is of arbitrary length but output is always of fixed length. Values returned by a hash function are called message digest or simply hash values. The following picture illustrated hash function −. WebWhy should hash functions exhibit the diffusion property then? Update 1: Given that you could use hashing functions for hiding information or for assuring the integrity of a document, I think it is a good idea to separate both aspects.
