The AES method is a block cipher which uses a block size of 128-bits and key sizes of 128 bits, 192 bits and 256 bits. It operates by uses a key scheduling method which takes part of the key for a number of rounds. For a 128-bit key, we have 10 rounds, and for a 256-bit key, we have 14 rounds. In each round, we take a 4ⅹ4 matrix of byte values (16 bytes = 128 bits), and then…
