Creator Serial Number (16 bytes): X.509 certificate serial number (as specified in [RFC2459]) of the GMC of the record creator.

Modifier Serial Number (16 bytes): The X.509 certificate serial number (as specified in [RFC2459]) of the GMC of the record modifier. For a record that has never been modified (that is, added but never updated), this number MUST be the same as the Creator Serial Number.

Signature (128 bytes): An RSA PKCS #1 signature with no hash algorithm OID [RFC8017] of the hash of the record data and properties using the asymmetric RSA key in the modifier's GMC. The syntax for the signature Hash is specified in section 2.2.4.1.
