(a) Let p=17 and q=31 and e=37, using RSA Encryption, encrypt the following message "I MATH", use the cipher from class for the letters (A=1, B=2, ... , Z=26), =27 and let a space be 28. You can use a calculator but you must show where the numbers come from. Also, remember that you will need to understand this for the upcoming test!

(b) Using the same numbers from above and find d, then decrypt the following message: 443, 240,328, 259, 267, 140, 1. Again you may use a calculator but you must show where the numbers come from.
