Crypt::Mac::Pelican

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.

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');
