NAME

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

SYNOPSIS

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

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

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

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

       Append specified data to the digest stream.

   digest
           $digest = $object->digest;

       Returns an octet string containing the calculated digest.

ACKNOWLEDGMENT

       Thanks are due to Eric Young and the many developers and contributors to the OpenSSL
       cryptographic library.
