What is a key difference between symmetric and asymmetric encryption?
Symmetric uses one key; asymmetric uses two.
Symmetric is for files; asymmetric for networks.
Symmetric is more secure.
Asymmetric uses only a single key.
Explication
Symmetric encryption uses the same key for both encryption and decryption, while asymmetric uses different keys.
