For what it's worth, if you're ever thinking about certifying KMAC, OpenSSL < 3.4 doesn't have a check. OpenSSL 3.4+ should have a check. |

The check_mac_fips_indicators() won't do anything for the CMACs, as the cmac implementation in FIPS provider does not implement this parameter. The AES key with SIGN/VERIFY flags was also not marked correctly as FIPS valid so any CMAC operation on that given key caused the FIPS indicator failure.

There were several issues:
check_mac_fips_indicators()won't do anything for the CMACs, as the cmac implementation in FIPS provider does not implement the fips indicator OSSL_PARAM.I am still not sure about the GCM as the specs are vague. Putting 64b for now.
