Remarks

Use the public key in the zero'th element of the AttestationCertificates to verify this signature. If no attestation certificate is provided, the authenticator assumes the entity that must verify the signature will have access to the appropriate cert.

The data to verify is the AuthenticatorData concatenated with the client data hash (from the MakeCredentialParameters).
