Problem
What is the difference between a symmetric (or secret-key) cryptosystem and an asymmetric (or public-key) cryptosystem? Justify your choice and give examples of either symmetric or asymmetric and its use cases. .
• Symmetric shares the key publicly while asymmetric does not
• Symmetric uses a single key while asymmetric needs a pair of public and private key
• Symmetric takes more time than asymmetric
• Symmetric provides encryption and the asymmetric does not.
