=head1 SYNOPSIS

use Net::DNS;
    $rr = new Net::DNS::RR('name IN CERT format tag algorithm cert');

=head1 DESCRIPTION

Class for DNS Certificate (CERT) resource records.

=head1 METHODS

The available methods are those inherited from the base class augmented
by the type-specific methods defined in this package.

Use of undocumented package features or direct access to internal data
structures is discouraged and could result in program termination or
other unpredictable behaviour.

=head2 format

$format =  $rr->format;

Returns the format code for the certificate (in numeric form)

=head2 tag

$tag = $rr->tag;

Returns the key tag for the public key in the certificate

=head2 algorithm

$algorithm = $rr->algorithm;

Returns the algorithm used by the certificate (in numeric form).

=head2 cert

$cert = $rr->cert;

Base64 representation of the certificate.

=head2 certbin

$certbin = $rr->certbin;

Binary representation of the certificate.
