What is an advantage of RSA over DSA?

A.
It can provide digital signature and encryption functionality.

B.
It uses fewer resources and encrypts quicker because it uses symmetric keys.

C.
It is a block cipher versus a stream cipher.

D.
It employs a one-time encryption pad.

Explanation:
RSA can be used for data encryption, key exchange, and digital
signatures. DSA can only be used for digital signatures.
