The following questions are based on scenario in which encrypted data are passed between Alice and Bob using RSA algorithm. Alice's public key is {17, 23} and Bob's public key is {5,23}. Assume that no one knows the private keys but the original owners.
i) Encrypt the message M=7 using Bob's public key.
ii) What should Alice have to do to decrypt the message from Q-2 a?
iii) What would Bob have to do to decrypt the message from Q-2 a?
iv) What is Alice's private key?
v) What is Bob's private key?
