  # Usage notes:
  #
  # The valid_security_key_auth_post_data is derived from an actual YubiKey login
  # attempt that is successful. No security risk is posed by this; this YubiKey
  # has only ever been used for local credentials.
  #
  # To make this all work together you need to
  # create a UserSecurityKey for a user using valid_security_key_data,
  # and you override Webauthn::ChallengeGenerator.generate to return
  # a Webauthn::ChallengeGenerator::ChallengeSession object using
  # valid_security_key_challenge_data.
  #
  # This is because the challenge is embedded
  # in the post data's authenticatorData and must match up. See
  # simulate_localhost_webautn_challenge for a real example.
