A system stores user passwords by hashing them with a salt. What is the primary purpose of using a salt?

To encrypt the password before storing it

To ensure that identical passwords produce different hashes

To reduce the length of the hash output

What is the correct order of the certificate lifecycle in a PKI?

Revocation, enrollment, issuance, use, expiration

Use, enrollment, issuance, expiration, revocation

Enrollment, issuance, use, expiration, revocation

Issuance, enrollment, use, revocation, expiration

An organization must rotate encryption keys annually for compliance. The current key encrypts a large data store. The team is concerned about downtime during rotation. Which rotation strategy minimizes downtime while maintaining security?

Keep the same key but change the algorithm to AES-256.

Re-encrypt all data with a new key during a maintenance window.

Disable encryption temporarily and re-enable with a new key.

Use a key hierarchy: encrypt the data encryption key (DEK) with a new key encryption key (KEK) and re-wrap the DEK.

Which of the following statements best describes symmetric encryption?

It uses a hash function to transform plaintext into ciphertext.

It uses the same key for both encryption and decryption.

It uses two different keys, one for encryption and one for decryption.

It uses a public key to encrypt and a private key to decrypt.
