Dec 18, 2008 · SHA-3 is not vulnerable to length extension attacks, as such, does not need HMAC to authenticate a message. So SHA-3(key||message) is a perfectly acceptable construction for authentication. NIST is working on standardizing a "KMAC" construction, for the SHAKE XOFs however. But a keyed SHA-3 does not need a separate HMAC construction.

HMAC user-input keys that are longer than the specific hash algorithms blocksize are first shortened. (By running the long keys through the hash. And then using that hash as the actual key.) SHA256 outputs 256 bit hashes. That's 32 bytes. So I suggest you generate 256 bit HMAC secret keys. (Using a cryptographically secure random generator.)

The accelerators include I/O registers, encryption and decryption cores, and the logic for feedback modes and key scheduling.
