Question

Quizplus · Accepted Answer

With symmetric encryption, the same key is used for both encoding and decoding. Asymmetric encryption (also known as public key encryption) uses two different keys for encoding and decoding. Option A is incorrect as asymmetric encryption is generally slower and more complex than symmetric encryption. Option B is incorrect as this is describing asymmetric encryption, not symmetric. Option D is incorrect as public key/private key encryption is a separate encryption method from symmetric encryption.
