WebHashing mainly works by mapping data of any arbitrary size to fixed-size value with the help of a function called “hash function” and storing it in a data structure called “hash table” at the value returned by hash functions. The values returned by this function are called hash codes, digests, hash values or hashes. WebA cryptographic hash function ( CHF) is a hash algorithm (a map of an arbitrary binary string to a binary string with fixed size of bits) that has special properties desirable for a cryptographic application: [1] the …
