Which two statements about symmetric encryption are true? (Choose two.) (SourcE. Understanding Cryptographic Fundamentals)

A. With symmetric encryption, the encryption key equals the decryption key.

B. Symmetric encryption is commonly used to sign asymmetric keys.

C. Symmetric encryption is a good choice for real-time encryption of bulk data.

D. Symmetric encryption uses asymmetric keys.

Answer: A,C

Explanation: Incorrect: BD

There are two basic techniques for encrypting information: symmetric encryption (also called secret key encryption) and asymmetric encryption (also called public key encryption.) in symmetric key As long as both sender and recipient know the secret key, they can encrypt and decrypt all messages that use this key. A public key is made freely available to anyone who might want to send you a message. A second, private key is kept secret, so that only you know it.
