Diagram showing the process of symmetric encryption: plaintext is encrypted with a key to produce ciphertext, which is then decrypted back to plaintext using the same key.

• Symmetric encryption uses the same key for both encryption and decryption.

• Symmetric encryption uses different keys for encryption and decryption.

• Symmetric encryption does not require a key for decryption.

• Symmetric encryption uses a public key for encryption and a private key for decryption.
