File::KDBX::Key::File - A file key

type
           $type = $key->type;

       Get the type of key file. Can be one of from ":key_file" in File::KDBX::Constants:

       •   "KEY_FILE_TYPE_BINARY"

       •   "KEY_FILE_TYPE_HEX"

       •   "KEY_FILE_TYPE_XML"

       •   "KEY_FILE_TYPE_HASHED"

   version
           $version = $key->version;

       Get the file version. Only applies to XML key files.

   filepath
           $filepath = $key->filepath;

       Get the filepath to the key file, if known.

       A file key (or "key file") is the type of key where the secret is a file. The secret is either the file
       contents or is generated based on the file contents. In order to lock and unlock a KDBX database with a
       key file, the same file must be presented. The database cannot be opened without the file.

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

       There are multiple types of key files supported. See "type". This module can read and write key files.

load
           $key = $key->load($filepath);
           $key = $key->load(\$string);
           $key = $key->load($fh);
           $key = $key->load(*IO);

       Load a key file.

   reload
           $key->reload;

       Re-read the key file, if possible, and update the raw key if the key changed.

   save
           $key->save;
           $key->save(%options);

       Write a key file. Available options:

       •   "type" - Type of key file (default: value of "type", or "KEY_FILE_TYPE_XML")

       •   "verson" - Version of key file (default: value of "version", or 2)

       •   "filepath" - Where to save the file (default: value of "filepath")

       •   "fh" - IO handle to write to (overrides "filepath", one of which must be defined)

       •   "raw_key" - Raw key (default: value of "raw_key")

       •   "atomic" - Write to the filepath atomically (default: true)

       File::KDBX::Key::File - A file key

           use File::KDBX::Constants qw(:key_file);
           use File::KDBX::Key::File;

           ### Create a key file:

           my $key = File::KDBX::Key::File->new(
               filepath    => 'path/to/file.keyx',
               type        => KEY_FILE_TYPE_XML,   # optional
               version     => 2,                   # optional
               raw_key     => $raw_key,            # optional - leave undefined to generate a random key
           );
           $key->save;

           ### Use a key file:

           my $key2 = File::KDBX::Key::File->new('path/to/file.keyx');
           # OR
           my $key2 = File::KDBX::Key::File->new(\$secret);
           # OR
           my $key2 = File::KDBX::Key::File->new($fh); # or *IO
