Attempt to look up attestation for a chain of certificates

If there is a signature path from any trusted certificate to the first certificate in attestationCertificateChain, then the first certificate in attestationCertificateChain is matched against the metadata registry to look up metadata for the device.

If the certificate chain is trusted but no metadata exists in the registry, the method returns a trusted attestation populated with information found embedded in the attestation certificate.

If the certificate chain is not trusted, the method returns an untrusted attestation populated with transports information found embedded in the attestation certificate.

If the certificate chain is empty, an untrusted empty attestation is returned.

Specified by:

getAttestation in interface com.yubico.webauthn.attestation.MetadataService

Parameters:

attestationCertificateChain - a certificate chain, where each certificate in the list should be signed by the following certificate.

Returns:

An attestation as described above.

Throws:

java.security.cert.CertificateEncodingException - if computation of the fingerprint fails for any element of attestationCertificateChain that needs to be inspected
