Is there an OpenSSL API available for AES-GMAC operation ? or is it through AES-GCM with plaintext zero only ? |

AES in combination with GMAC is AES-GCM - but I think you mean GMAC as a standalone operation. In which case, yes. You can use the EVP_MAC APIs: https://www.openssl.org/docs/man3.3/man7/EVP_MAC-GMAC.html |
