DES is often defined as no longer “secure enough” to handle high security requirements. Why is
this?

A.
DES is more vulnerable to dictionary attacks than other algorithms

B.
DES is more vulnerable to brute-force attacks than other algorithms

C.
DES uses a 32-bit key length, which can be cracked easily

D.
DES uses a 64-bit key, which can be cracked easily

E.
The DES key can be cracked in a short time
