A straightforward test of encrypting and decrypting an eight-letter message with the Substitution Cipher. Message letters are generated uniformly at random from the English alphabet and the key is a uniformly chosen random permutation of the alphabet. Students are expected to be able to map English letters onto elements of Z26 in the usual order.
