Quizplus · Accepted Answer

Symmetric encryption uses the same key for both encoding (encrypting) and decoding (decrypting) the data. This makes it faster and simpler than asymmetric encryption (option B), where two different keys are used for encryption and decryption. Symmetric encryption requires a key (option C) and is not typically used with public/private keys (option D).
