Explain how asymmetric encryption works and how it differs from symmetric encryption.

Asymmetric encryption uses a pair of keys: a public key and a private key. The public key is used for encrypting data, while the private key is used for decrypting it. This allows secure data exchange without prior sharing of a secret key.

Unlike symmetric encryption, where the same key is used for both encryption and decryption, asymmetric encryption provides a higher level of security when transmitting keys.

Example: when sending an encrypted message, you use the recipient's public key, and they decrypt the message with their private key.
