Question

Which of the following is not a best practice for cryptographic key management?

A: Keys should be transmitted and stored by secure means.
B: Keys should be properly destroyed when their lifetime ends.
C: Keys should be presented in clear text.
D: Key values should be random, and the full spectrum of the keyspace should be used.

Answer 1

The best practice for cryptographic key management is to not present keys in clear text.

Step-by-step explanation:

The correct answer is option C: Keys should be presented in clear text. This is not a best practice for cryptographic key management because it makes the keys vulnerable to unauthorized access. In cryptography, keys should be kept secret and not revealed in clear text. By presenting the keys in clear text, anyone who intercepts the communication can easily obtain the keys and compromise the security of the system.
