Hashing algorithms are mathematical functions used specifically to generate deterministic results from arbitrary data (a hash value) for the purpose of verifying the integrity of a file or string of data. The algorithm takes a variable–length input and produces a fixed–length output. Common hashing algorithms used in computing include MD5, SHA–1, and SHA–256.
Hashing algorithms are mathematical functions that take a variable length input and convert it into a fixed length output. These algorithms are used for a variety of purposes, including data security, encryption, data integrity, indexing data structures, and more. The output of a hashing algorithm is known as a “hash” or a “digest”.
