B)Symmetric key encryption
C)Public key encryption
D)Private key encryption

Question

Quizplus · Accepted Answer

In symmetric key encryption, a single encryption key (also called a secret key) is used to both encrypt and decrypt data. The same key is shared between the sender and the receiver, so there is no need to exchange keys securely beforehand. This makes symmetric key encryption faster and more efficient than public key encryption, which requires a separate encryption key and decryption key. SSL is a protocol that uses public key encryption, and private key encryption is also known as asymmetric key encryption, where a different key is used for encryption and decryption.
