Public/private key encryption relies on the fact that there is no known formula for factoring large numbers greater than ____ digits.
A) 75
B) 80
C) 110
D) 150

Question

Quizplus · Accepted Answer

The current recommendation is to use a minimum of 2048-bit key for public/private key encryption. As the number of bits increases, the number of possible keys increases exponentially, making it harder to brute-force the encryption. At a key length of 80 bits, there are already 2^80 possible keys, making it difficult to brute-force the encryption.
