Encrypt the plain text \( (P)= \) 'NEVERSAYNEVER' to cipher text \( (C) \) using the affine cipher rule \( C=x * P+y \) with the following keys i. \( x=2, y=0 \); ii. \( x=4, y=0 \) iii. \( x=6, y=0 \) iv. \( x=8, y=0 \) Answer the following- a) What is the problem with these keys? b) Did you find any specific/fixed pattern within the cipher text using these keys? If yes, what is that pattern? c) Now consider \( x \) is always an even number and \( y \) is always 0 . What conclusion you can draw about encrypting the given plain text \( P \) ?
