What are the differences between symmetric and asymmetric encryption methods, and when is each used?
Symmetric encryption uses a single key to both encrypt and decrypt data, while asymmetric encryption uses a public-private key pair for encryption and decryption. Symmetric encryption is faster and more suitable for encrypting large amounts of data, like in bulk data transfers. Asymmetric encryption provides better security and is commonly used for secure communication, key exchange, and digital signatures.
