i need the solution in steps

8. We would like to use the permutation to encrypt Information Security a. Convert the text to its ASCII code numbers and convert the decimal numbers to binary bits (8-bits basis)? Note .... I \& S are capital letters and a space between the 2 words b. Use the permutation (2,5,4,6,1,3) to encrypt the message. These are 6 bits blocks, so you need to group them based on that? Add zeros if you need as a pad c. Now if you need to decrypt the message what will be the key to be used
