The getPublicKeyAlgorithm()
method of the AuthenticatorAttestationResponse
interface returns a number that is equal to a COSE Algorithm Identifier, representing the cryptographic algorithm used for the new credential.
This is a convenience function created to allow easy access to the algorithm type. This information will need to be stored in order to verify future authentication operations (i.e., using navigator.credentials.get()
).
