Instance properties

Also inherits properties from its parent, AuthenticatorResponse.

AuthenticatorAttestationResponse.attestationObject Read only: An ArrayBuffer containing authenticator data and an attestation statement for a new key pair generated by the authenticator.
AuthenticatorResponse.clientDataJSON Read only: Inherited from AuthenticatorResponse, this property contains the JSON-compatible serialization of the data passed from the browser to the authenticator in order to generate this credential — i.e., when CredentialsContainer.create() is called with a publicKey option. This data contains some information from the options passed into the create() call, and some information controlled by the browser.

Instance methods

AuthenticatorAttestationResponse.getAuthenticatorData(): Returns an ArrayBuffer containing the authenticator data contained within the AuthenticatorAttestationResponse.attestationObject property.
AuthenticatorAttestationResponse.getPublicKey(): Returns an ArrayBuffer containing the DER SubjectPublicKeyInfo of the new credential (see Subject Public Key Info), or null if this is not available.
AuthenticatorAttestationResponse.getPublicKeyAlgorithm(): Returns a number that is equal to a COSE Algorithm Identifier, representing the cryptographic algorithm used for the new credential.
AuthenticatorAttestationResponse.getTransports(): Returns an array of strings describing which transport methods (e.g., usb, nfc) are believed to be supported with the authenticator. The array may be empty if the information is not available.
