About Digital Hashes

A hash function is a mathematical algorithm that maps data of arbitrary size to a bit string of a fixed size (a hash). It is a one-way function, meaning it is practically impossible to invert. Hashes are commonly used for data integrity checks, digital signatures, and password storage.
