=head1 NAME
Net::DNS::SEC - DNSSEC extensions to Net::DNS
=head1 SYNOPSIS
use Net::DNS::SEC;
=head1 DESCRIPTION
The Net::DNS::SEC suite provides additional packages required to support
DNSSEC as described in RFC4033, RFC4034, RFC4035 and subsequent related
documents.
Net::DNS::SEC is installed as an extension to an existing Net::DNS
installation.
The extended features are made available by substituting Net::DNS::SEC
for Net::DNS in the use declaration.

=head1 UTILITY FUNCTIONS
=head2 algorithm
$mnemonic = algorithm( 5 );
$numeric = algorithm( 'RSA-SHA1' );
print "algorithm mnemonic\t", $mnemonic, "\n";
print "algorithm number:\t", $numeric, "\n";
algorithm() provides conversions between an algorithm code number and
the corresponding mnemonic.
=cut
sub algorithm { &Net::DNS::RR::DS::algorithm; }
=head2 digtype
$mnemonic = digtype( 2 );
$numeric = digtype( 'SHA-256' );
print "digest type mnemonic\t", $mnemonic, "\n";
print "digest type number:\t", $numeric, "\n";
digtype() provides conversions between a digest type number and the
corresponding mnemonic.
=cut
sub digtype { &Net::DNS::RR::DS::digtype; }
=head2 key_difference
@result = key_difference( \@a, \@b );
Fills @result with all keys in array @a that are not in array @b.
=cut

my $a = shift;
my $b = shift;
my $r = shift || []; ## 0.17 interface
