NAME

       Net::DNS::SEC::Digest - Message Digest Algorithms

SYNOPSIS

           require Net::DNS::SEC::Digest;

           $object = new Net::DNS::SEC::Digest::SHA(256);
           $object->add($text);
           $object->add($more);
           $digest = $object->digest;

DESCRIPTION

       Interface package providing access to the message digest algorithm implementations within
       the OpenSSL libcrypto library.

METHODS

   new
           require Net::DNS::SEC::Digest;
           $object = new Net::DNS::SEC::Digest::SHA( $algorithm );

       Creates and initialises a new digest object instance for the specified algorithm.

   add
           $object->add($text);
           $object->add($more);

       Append specified text to digest stream.

   digest
           $digest = $object->digest;

       Returns the digest encoded as a binary string.
