Explain the strengths and weaknesses of using symmetric encryption, like AES, versus a public-key cryptosystem, like RSA

What will be an ideal response?

Symmetric algorithms, like AES, are fast to perform encryption and decryption,
but they have a setup challenge in that Alice and Bob have to figure out some way to share
the secret key. In a public-key cryptosystem, there is no problem in setting up any secret
key, but the encryption and decryption algorithms are slower.
