NAME
       Crypt::Mac::Pelican - Message authentication code Pelican (AES based MAC)

SYNOPSIS
          ### Functional interface:
          use Crypt::Mac::Pelican qw( pelican pelican_hex );

          # calculate MAC from string/buffer
          $pelican_raw  = pelican($key, 'data buffer');
          $pelican_hex  = pelican_hex($key, 'data buffer');
          $pelican_b64  = pelican_b64($key, 'data buffer');
          $pelican_b64u = pelican_b64u($key, 'data buffer');

          ### OO interface:
          use Crypt::Mac::Pelican;

          $d = Crypt::Mac::Pelican->new($key);
          $d->add('any data');
          $d->addfile('filename.dat');
          $d->addfile(*FILEHANDLE);
          $result_raw  = $d->mac;     # raw bytes
          $result_hex  = $d->hexmac;  # hexadecimal form
          $result_b64  = $d->b64mac;  # Base64 form
          $result_b64u = $d->b64umac; # Base64 URL Safe form

DESCRIPTION
       Provides an interface to the Pelican message authentication code (MAC) algorithm.

EXPORT
       Nothing is exported by default.

       You can export selected functions:

         use Crypt::Mac::Pelican qw(pelican pelican_hex );

       Or all of them at once:

         use Crypt::Mac::Pelican ':all';

FUNCTIONS
   pelican
       Logically joins all arguments into a single string, and returns its Pelican message
       authentication code encoded as a binary string.

        $pelican_raw = pelican($key, 'data buffer');
        #or
        $pelican_raw = pelican($key, 'any data', 'more data', 'even more data');

   pelican_hex
       Logically joins all arguments into a single string, and returns its Pelican message
       authentication code encoded as a hexadecimal string.

        $pelican_hex = pelican_hex($key, 'data buffer');
        #or
        $pelican_hex = pelican_hex($key, 'any data', 'more data', 'even more data');

   pelican_b64
       Logically joins all arguments into a single string, and returns its Pelican message
       authentication code encoded as a Base64 string.

        $pelican_b64 = pelican_b64($key, 'data buffer');
        #or
        $pelican_b64 = pelican_b64($key, 'any data', 'more data', 'even more data');

   pelican_b64u
       Logically joins all arguments into a single string, and returns its Pelican message
       authentication code encoded as a Base64 URL Safe string (see RFC 4648 section 5).

        $pelican_b64url = pelican_b64u($key, 'data buffer');
        #or
        $pelican_b64url = pelican_b64u($key, 'any data', 'more data', 'even more data');

METHODS
   new
        $d = Crypt::Mac::Pelican->new($key);

   clone
        $d->clone();

   reset
        $d->reset();

   add
        $d->add('any data');
        #or
        $d->add('any data', 'more data', 'even more data');

   addfile
        $d->addfile('filename.dat');
        #or
        $d->addfile(*FILEHANDLE);

   mac
        $result_raw = $d->mac();

   hexmac
        $result_hex = $d->hexmac();

   b64mac
        $result_b64 = $d->b64mac();

   b64umac
        $result_b64url = $d->b64umac();
