HMAC is actually overkill for SHA-3 (Keccak); SHA-3 should be secure even without the HMAC construct. By now KMAC has been standardized as MAC construct for SHA-3. The SHA-2 constructs have - somewhat surprisingly - shown pretty good resistance against crypt-analysis during the SHA-3 Aug 31, 2016 · NETWORK SECURITY - HMAC ALGORITHM - Duration: 20:58.

For example, the HMAC-IP-59 is the hash core embedded in the IPsec packet engines as well as Vault-IP platform security engines providing support for MD5 and SHA based Hash and HMAC functions. 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.

An HMAC is a fixed-length string of bits similar to other hashing algorithms such as MD5 and SHA-1 (known as HMAC-MD5 and HMAC-SHA1). However, HMAC also uses a shared secret key to add some randomness to the result and only the sender and receiver know the secret key.
