Question 2 12.5 pts I've encoded my first name (ANDY, in 7-bit ASCII as in Problem 1) using the simple binary substitution cipher discussed in class and on page 247 in Singh, using the 7-bit ASCII representation of a four-letter word as the key. The resulting ciphertext is: 0010001000111100101110001010 Type in the four letter word (using the English alphabet, i.e., not in binary) that I used for the key. Don't forget that the ASCII codes are listed on page 246 of Singh.
