e) Alice wishes to sign a document and send it to Bob using RSA signatures. Suppose she generates two primes p = 7, q = 11, and a public exponent e =43, and publishes (n. e) as her public key (6 Marks) i) What would her private key be? ii) Suppose Alice has a message m = 3. Explain how she can use RSA to sign m and find the corresponding signature for m = 3. f) Explain the term salt in the context of cryptography and elaborate how they make passwords more difficult to break.
