Question

Quizplus · Accepted Answer

Symmetric encryption uses a single key for both encryption and decryption.

Answer: E 
 Asymmetric encryption uses two different keys for encryption and decryption, also known as public and private keys.

Answer: A, D 
 Encryption refers to the process of converting plain text into a coded format. Decryption is the reverse process of converting the coded format back to plain text. Cryptography is the practice of secure communication in the presence of third parties. However, none of these options specify the use of a single key for encryption and decryption, so neither of them is the best choice.
