Hashing Algorithm Overview: Types, Methodologies

WebSep 29, 2024 · It is a mathematical algorithm that maps data of arbitrary size to a bit string of a fixed size (a hash function) which is designed to also be a one-way function, that is, a function which is infeasible to invert (Source : Wiki ). WebApr 12, 2024 · A hash function is another method involved in data encryption. Hashing uses an algorithm to translate data of any size to a fixed length, resulting in a hash value, rather than the ciphertext produced by encryption algorithms. Hashing is used to verify that data has not been altered from its previous state during transmission. gps wilhelmshaven personalabteilung
