# Crypt::Mac::Pelican - phpMan

## 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();
