What’s the difference between symmetric and asymmetric encryption?Dec 16, 2024

I’m trying to understand encryption methods. Could someone explain the key differences between symmetric and asymmetric encryption, and when I would use each?

  • Symmetric encryption uses the same key for both encryption and decryption (e.g., AES). It’s fast but requires secure key management.
  • Asymmetric encryption uses a pair of keys: a public key for encryption and a private key for decryption (e.g., RSA). It’s slower but provides better security for key exchange and digital signatures.

Use symmetric encryption when you need to encrypt large amounts of data efficiently. Use asymmetric encryption for secure communication, like in SSL/TLS or digital signatures.
