# File::KDBX::Key::Composite(3pm)

A composite key made up of component keys

## NAME

File::KDBX::Key::Composite - A composite key made up of component keys

## VERSION

version 0.906

## SYNOPSIS

```
    use File::KDBX::Key::Composite;
    my $key = File::KDBX::Key::Composite->(\@component_keys);
```

## DESCRIPTION

A composite key is a collection of other keys. A master key capable of unlocking a KDBX database is always a composite key, even if it only has a single component.

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

## ATTRIBUTES

### keys

```
    \@keys = $key->keys;
```

Get one or more component File::KDBX::Key.

## METHODS

### raw\_key

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

Get the raw key from each component key and return a generated composite raw key.

### challenge

```
    $response = $key->challenge(...);
```

Issues a challenge to any File::KDBX::Key::ChallengeResponse components keys. Arguments are passed through to each component key. The responses are hashed together and the composite response is returned.

Returns empty string if there are no challenge-response components keys.
