Hash

A hash algorithm is a mathematical function that converts input data (of any size) into a fixed-length string, called a hash value or digest. Hash functions are commonly used in cryptography, data integrity verification, and password storage because they produce unique outputs for different inputs and are designed to be irreversible. Popular hash algorithms include MD5, SHA-1, and SHA-256.
