Question

Difference between mac and hash function in tabular form

Answer 1

Answer:In simple words

MAC algorithm is a symmetric key cryptographic technique to provide message authentication. ... Similar to hash, MAC function also compresses an arbitrary long input into a fixed length output. The major difference between hash and MAC is that MAC uses secret key during the compression.

Answer 2

Hash function:

A hash function is any function that can be used to map data of random size to fixed-size values. The values reverted by a hash function are called hash values, hash codes, digests, or merely hashes. The values are used to index a fixed-size table named a hash table.

Mac function:

MAC algorithm is a symmetric key cryptographic method to deliver message authentication. For starting MAC process, the source and receiver share a symmetric key K.
