... 5. Consider the association between letters/symbols and numbers where A is 0, B is 1, Z is 25, and space is 26. I have used RSA to (poorly) encrypt a message in the following way. I took each symbol of my message, converted it to a number n, randomly added 0 or 1 to 2n to get a number 0 m < 53, then using my public key (N,e) (77, 7) I encrypted it as me % N. This yielded the following sequence of numbers: = 12 50 63 41 4 68 63 31 (a) Break RSA and calculate my private key. (b) Decrypt my message!
