What is the main difference between symmetric and asymmetric encryption?

Group of answer choices

Symmetric encryption is faster and less computationally intensive than asymmetric encryption

Symmetric encryption uses different keys for encryption and decryption, while asymmetric encryption uses the same key for both

Both symmetric and asymmetric encryption can be used for key exchange and encryption

Asymmetric encryption is typically used for key exchange and digital signatures, while symmetric encryption is typically used for bulk data encryption
