Hash, generally translated as "hash", but also directly transliterated as "hash", is to convert input of any length (also called pre-mapping, pre-image) into a fixed length through a hash algorithm The output is the hash value. This conversion is a compressed mapping, that is, the space of hash values ??is usually much smaller than the space of inputs. Different inputs may hash into the same output, so it is impossible to uniquely determine the input value from the hash value. Simply put, it is a function that compresses a message of any length into a message digest of a fixed length.
