To use symmetric-key cryptography, the sender and receiver can use a session key, which will only be valid during the one session. For complete privacy, two different keys are more secure. In asymmetric-key, two pairs of keys are used, but not shared. In a 2-way conversation, each person will make a public and a private key, and the receiver will user their pair of keys to encrypt and decrypt. Define and describe message integrity.
