What is the difference between symmetric and asymmetric encryption?

  1. ASymmetric encryption uses the same key for encryption and decryption, while asymmetric encryption uses different keys for encryption and decryption.
  2. BAsymmetric encryption uses the same key for encryption and decryption, while symmetric encryption uses different keys for encryption and decryption.
  3. CSymmetric encryption uses a single key for encryption, while asymmetric encryption uses multiple keys for encryption.
  4. DAsymmetric encryption uses a single key for encryption, while symmetric encryption uses multiple keys for encryption.
Show answerHide answer

Correct answer: (A) Symmetric encryption uses the same key for encryption and decryption, while asymmetric encryption uses different keys for encryption and decryption.

Explanation

Symmetric encryption, such as AES, uses one shared key to both encrypt and decrypt. Asymmetric encryption, such as RSA, uses a public key and a private key.
