NAME

       Net::DNS::SEC - DNSSEC extensions to Net::DNS

SYNOPSIS

           use Net::DNS::SEC;

DESCRIPTION

       Net::DNS::SEC is installed as an extension to an existing Net::DNS installation providing
       packages to support DNSSEC as specified in RFC4033, RFC4034, RFC4035 and related
       documents.

       It also provides support for SIG0 which is useful for dynamic updates.

       Implements cryptographic signature generation and verification functions using RSA, DSA,
       ECDSA, and Edwards curve algorithms.

       The extended features are made available by replacing Net::DNS by Net::DNS::SEC in the use
       declaration.

UTILITY FUNCTIONS

   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.

   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.

   key_difference
           @result = key_difference( \@a, \@b );

       Fills @result with all keys in array @a that are not in array @b.
