Alice оften needs tо encipher plаintext mаde оf letters (а to z), digits (0 to 9), spaces, commas, periods, and question marks. [10 points] How many keys can be used if a multiplicative cipher is used? (A multiplicative cipher is defined as c = k1*p (mod n) where n is the number of symbols, k1 is the single key.) [5 points] How many key pairs can be used if an affine cipher is used? (An affine cipher is defined as c = (k1*p + k2) (mod n) where n is the number of symbols, k1 and k2 are the two keys.)
