=head1 METHODS

=head2 new (from private keyfile)

	$keypath = '/home/foo/Kexample.com.+013+26512.private';
	$private = Net::DNS::SEC::Private->new( $keypath );

The argument is the full path to a private key file generated by the
BIND dnssec-keygen tool.  Note that the filename contains information
about the algorithm and keytag.


=head2 new (from private key parameters)

	$private = Net::DNS::SEC::Private->new(
		'algorithm'  => '13',
		'keytag'     => '26512',
		'privatekey' => 'h/mc+iq9VDUbNAjQgi8S8JzlEX29IALchwJmNM3QYKk=',
		'signame'    => 'example.com.'
		);

The arguments define the private key parameters as (name,value) pairs.
The name and data representation are identical to that used in a BIND
private keyfile.


=head2 private_key_format

	$format = $private->private_key_format;

Returns a string which identifies the format of the private key file.


=head2 algorithm, keytag, signame
	
	$algorithm = $private->algorithm;
	$keytag	   = $private->keytag;
	$signame   = $private->signame;

Returns the corresponding attribute determined from the filename.


=head2 Private key attributes

	$attribute = $private->attribute;

Returns the value as it appears in the private key file.
The attribute names correspond to the tag in the key file, modified
to form an acceptable Perl subroutine name.


=head2 created, publish, activate

	$created  = $private->created;
	$publish  = $private->publish;
	$activate = $private->activate;

Returns a string which represents a date in the form 20141212123456.
Returns undefined value for key formats older than v1.3.
