How does HMAC process differ from the MAC process?

Group of answer choices

HMAC produces $512-$bit hashes as opposed the $256-$bit hashes produced by a MAC.

The HMAC process uses a secret key to perform the hashing. The MAC process does not use a key, so it cannot be authenticated.

The HMAC process does not require a secret key, while the MAC process uses a secret key. This makes HMAC more secure as there$$s no need for the sender and recipient to exchange keys.

In addition to providing authentication, the HMAC process provides error correction capability. It can be used to detect and repair bits that were changed during transmission.

The HMAC process hashes the message twice, making it impervious to Length Extension Attacks. The MAC process only performs a single hash, leaving it vulnerable to Length Extension Attacks.

None of the above
