WebNov 3, 2024 · Hashing is a way to turn data into a fixed-length code mathematically. This code is typically shorter than the original data, making it faster and easier to work with. Hashing is used in many areas of cyber security, such as verifying data integrity, storing passwords, and generating unique identifiers. A hash function takes a key as an input, which is associated with a datum or record and used to identify it to the data storage and retrieval application. The keys may be fixed length, like an integer, or variable length, like a name. In some cases, the key is the datum itself. The output is a hash code used to index a hash table holding the data or records, or pointers to them. A hash function may be considered to perform three functions:

In computing, a hash table, also known as hash map, is a data structure that implements an associative array or dictionary. It is an abstract data type that maps keys to values.
