Explanation:
Detailed explanation-1: -Goals: To review the overall structure of AES and to focus particularly on the four steps used in each round of AES: (1) byte substitution, (2) shift rows, (3) mix columns, and (4) add round key.
Detailed explanation-2: -AES is primarily used to encrypt bulk data. Symmetric algorithms, of any kind, are used to encrypt large amounts of data, while asymmetric algorithms are used to encrypt a small amount of data as in keys and hashing values.
