What is the difference between symmetric and asymmetric encryption, and when would you use each one?

Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses a pair of public and private keys. Symmetric encryption is generally faster and more efficient for encrypting large amounts of data, while asymmetric encryption is more secure and allows for secure communication between parties without needing to share a key beforehand.

It is recommended to use symmetric encryption for encrypting large amounts of data or for communication between trusted parties who already have a shared key. Asymmetric encryption is ideal for secure communication over untrusted networks or when there is a need for secure key exchange between parties.

In summary, symmetric encryption is faster and more efficient, while asymmetric encryption is more secure and suitable for key exchange in secure communication.
