Here is the encryption key for an affine transformation like we saw in lecture: C = 5P + 2. This time, we are using arithmetic mod 27, where the characters a,.,z are mapped to the numbers 0 through 25 and the space character is mapped to 26. •.. a) What is the endcoding of "hello" as a string of characters? Show work. b) What is the decryption key for this transformation? Show work. c) Decode the message "mco". Show work.
