B)flat
C)long
D)thin

Question

Quizplus · Accepted Answer

RSA, being a public-key cryptography algorithm, is computationally intensive and thus very slow for encrypting and decrypting long messages. For efficiency, it's often used to encrypt the keys of faster symmetric-key algorithms, which then encrypt the actual messages.
