PS: Please explain that how you find "xx" step by step.

Below is the encryption step for the AES cipher with a possible 4 x 4 byte data (in hexadecimal notation) in a loop. After SubBytes After ShiftRows After MixColumns XX f7 27 9 54 ab 43 83 65 31 40 a9 3d fo d3 ff 3f 1- Show After ShiftRows 2- Find MixColumns for only "xx" Note: AES encrypt uses irreducible polynomial x8 + x4 + x3 + x + 1
