What is an advantage of RSA over the DSA?
A.
It can provide digital signature and encryption functionality.
B.
It uses fewer resources and encrypts faster because it uses symmetric keys.
C.
It is a block cipher rather than a stream cipher.
D.
It employs a one-time encryption pad.
Explanation:
A: RSA can be used for data encryption, key exchange, and digital signatures. DSA can be used only for digital signatures.
