What are the primary differences between symmetric and asymmetric encryption, and provide a practical use case for each?

Symmetric and asymmetric encryption are two fundamentally different approaches to encrypting data. The primary difference is the key usage. Symmetric encryption uses the same secret key for both encryption and decryption. This means that the sender and receiver must both possess the same key. Examples of symmetric encryption algorithms include AES (Advanced Encryption Standard) and DES (Data Encryption Standard). Symmetric encryption is generally faster and more efficient than asymmetric encryption, making it suitable for encrypting large amounts of dat....
