Overview

A challenge-response key is kind of like multifactor authentication, except you don't really authenticate to a KDBX database because it's not a service. Specifically it would be the "what you have" component. It assumes there is some device that can store a key that is only known to the owner of a database. A challenge is made to the device and the response generated based on the key is used as the raw key.

Inherets methods and attributes from File::KDBX::Key.

This is a generic implementation where a responder subroutine is provided to provide the response. There is also File::KDBX::Key::YubiKey which is a subclass that allows YubiKeys to be responder devices.

Methods

    $raw_key = $key->raw_key;
    $raw_key = $key->raw_key($challenge);

    $response = $key->challenge($challenge, @options);
