What does AES accomplish?

A.
Key recovery

B.
Symmetric key distribution

C.
Bulk data encryption

D.
Message integrity

Explanation:
Advanced Encryption Standard uses the Rijndael algorithm. It is a
symmetric algorithm, which is used to encrypt bulk data. Symmetric keys are not used
in key recovery; asymmetric algorithms are used for that purpose. And hashing
algorithms are used to create message digests, which is used for data integrity.
