A hash function is any function that can be used to map data of arbitrary size to data of fixed size.The values returned by a hash function are called hash values, hash codes, hash sums, or simply hashes. One use is a data structure called a hash table, widely used in computer software for rapid data lookup.Hash functions accelerate table or database lookup by detecting duplicated records in a large file.he values returned by a hash function are called hash values, hash codes, hash sums, or simply hashes. One use is a data structure called a hash table, widely used in computer software for rapid data lookup.
Protect a Password Database with a One-way Hash. A one-way hash function is a cryptographic algorithm that turns an arbitrary-length input into a fixed-length binary value, and this transformation is one-way, that is, given a hash value it is statistically infeasible to re-create a document that would produce this value. There are three widely used hash algorithms: MD4, MD5, and SHA.
