State symmetric versus asymmetric encryption precisely and explain why it matters in 2-3 sentences.

# Symmetric vs Asymmetric Encryption **Symmetric encryption** uses the same key for both encryption and decryption, while **asymmetric encryption** uses a mathematically related key pair: a public key for encryption and a private key for decryption (or vice versa for digital signatures). This distinction matters because symmetric encryption is much faster and efficient for large data volumes, but requires secure key exchange beforehand, whereas asymmetric encryption solves the key distribution problem by allowing anyone to encrypt with a public key that only the private key holder can decrypt—making it essential for secure communication between parties who have never met. Modern systems typically combine both: asymmetric encryption to securely exchange a symmetric key, then symmetric encryption for the actual data transfer.
