Overview

Action Pack WebAuthn None Attestation Verifier

Verifies attestation responses with the “none” format, which indicates the authenticator did not provide any attestation statement. This is the default format used by most consumer authenticators.

Implementing Custom Verifiers

To support other attestation formats (e.g., “packed”, “fido-u2f”), implement a class with the same verify! interface and register it:

Unmagic::Passkeys::WebAuthn.register_attestation_verifier("packed", MyPackedVerifier.new)

The verify! method receives the decoded Attestation object and the raw client_data_json bytes. Raise InvalidResponseError if verification fails.
