1. encrypt the message "boston" with the generalized caesar cipher f(p) ≡ 3(p − 10) mod 26
2. find the decryption function. your work must include the step-by-step process of finding the inverse.
3. use the decryption function to decrypt your earlier answer.
4. repeat the previous 3 questions, but this time use a two character block cipher with f(p) ≡ 707p + 15432 mod 123889
