, Which description about hash functions is NOT correct?  The hash function always takes a fixed size input. Hash functions should be easy to compute. Hash functions are one-way transformations. The size of the output of a hash function is always fixed.   2, Which description about hash functions is correct?  Hash functions are controlled by a secret key. It should be hard for attackers to find collisions of a secure hash function. The hash functions with long hash values have more collisions. Hash functions generate longer outputs for longer inputs.

Hash Table

A hash table also called a hash map, is a data structure that maps key-value pairs. The hash table can be used in complex systems to provide fast access and compact storage. A hash table is a structure that stores data in an abstract data type kind of associative array. It keeps data in an array format, with a distinct index value for every data value. If the index of the required data is known, then the data can be accessed very easily.
