What is the primary purpose of using one-way hashing on user passwords?

A.
It minimizes the amount of primary and secondary storage needed to store passwords.

B.
It prevents anyone from reading passwords in plaintext.

C.
It avoids excessive processing required by an asymmetric algorithm.

D.
It prevents replay attacks.

Explanation:
B: Passwords are usually run through a one-way hashing algorithm so the actual password is not transmitted across the network or stored on the authentication server in plaintext. This greatly reduces the risk of an attacker being able to obtain the actual password.
