SYNOPSIS

12           use File::KDBX::Key::ChallengeResponse;
13
14           my $responder = sub {
15               my $challenge = shift;
16               ...;    # generate a response based on a secret of some sort
17               return $response;
18           };
19           my $key = File::KDBX::Key::ChallengeResponse->new($responder);

DESCRIPTION

22       A challenge-response key is kind of like multifactor authentication,
23       except you don't really authenticate to a KDBX database because it's
24       not a service. Specifically it would be the "what you have" component.
25       It assumes there is some device that can store a key that is only known
26       to the owner of a database. A challenge is made to the device and the
27       response generated based on the key is used as the raw key.
28
29       Inherets methods and attributes from File::KDBX::Key.
30
31       This is a generic implementation where a responder subroutine is
32       provided to provide the response. There is also
33       File::KDBX::Key::YubiKey which is a subclass that allows YubiKeys to be
34       responder devices.
35

METHODS

37   raw_key
38           $raw_key = $key->raw_key;
39           $raw_key = $key->raw_key($challenge);
40
41       Get the raw key which is the response to a challenge. The response will
42       be saved so that subsequent calls (with or without the challenge) can
43       provide the response without challenging the responder again. Only one
44       response is saved at a time; if you call this with a different
45       challenge, the new response is saved over any previous response.
46
47   challenge
48           $response = $key->challenge($challenge, @options);
49
50       Issue a challenge and get a response, or throw if the responder failed
51       to provide one.
