Hello, let's have a look on this question.
00:03
So here we are using matrix a, that is 1, 243 for encrypting the message.
00:09
So according to the information, go to plan b.
00:16
This is 7, 15, 0, 20, 15, 0, 16, 12, 2, 14, 0 and 2.
00:30
So when we write it in the matrix form, this will be 7, 15, 0, 20, 15, 0, 16, 12, 1, 14 and 0, 14 and 02...
