Alice wants to engage in a private conversation with Bob. Accordingly, she generates a pair of cryptographic keys ("Alice-A" and "Alice- B") using the "Diffie-Helman" method that we discussed in class. Likewise, Bob also generates a pair of cryptographic keys ("Bob-A' and "Bob-B") using the same method. Alice then sends her "Alice-A" key to Bob, and Bob sends his "Bob-A key to Alice. What of the following statement(s) MUST be true?

a. Alice-A is a public key
b. Bob-A is a public key
c. Alice-A can only be used to encrypt information
d. Alice-B can only be used to decrypt information
e. Bob-A can be used to decrypt information that was encrypted using
f. Bob-B
g. None of the above.
h. Moving to another question will save this response.
