Concept Breakdown: What is the difference between symmetric and asymmetric encryption?

In asymmetric encryption, two different keys are used for encryption and decryption. One key (public key) is used for encryption and the other (private key) for decryption. It is slower than symmetric encryption but enables secure key exchange.

Key exchange is a method in cryptography by which cryptographic keys are exchanged between two parties, allowing use of a cryptographic algorithm. If the key is intercepted, the communication is compromised.

In symmetric encryption, the same key is used for both encryption and decryption. It is faster but less secure for key distribution due to the risk of the key being intercepted.
