Using s-des, decrypt the string (10100010) usingthe key (001) by hand. show intermediate results after eachfunction (ip, fk, sw, fk, ip-1).then decode the first 4 bits of the plaintext string to a letterand the second 4 bits to another letter where we encode a through pin base 2 (i. e., a = , b = p = ).
hint: as amidway check, after the application of sw, the string should be(00010011).
