=head1 NAME

Crypt::Mac::OMAC - Message authentication code OMAC

=head1 SYNOPSIS

### Functional interface:
   use Crypt::Mac::OMAC qw( omac omac_hex );

# calculate MAC from string/buffer
   $omac_raw  = omac($cipher_name, $key, 'data buffer');
   $omac_hex  = omac_hex($cipher_name, $key, 'data buffer');
   $omac_b64  = omac_b64($cipher_name, $key, 'data buffer');
   $omac_b64u = omac_b64u($cipher_name, $key, 'data buffer');

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

$d = Crypt::Mac::OMAC->new($cipher_name, $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

=head1 DESCRIPTION

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

=head1 EXPORT

Nothing is exported by default.

You can export selected functions:

use Crypt::Mac::OMAC qw(omac omac_hex );

Or all of them at once:

use Crypt::Mac::OMAC ':all';

=head1 FUNCTIONS

=head2 omac

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

$omac_raw = omac($cipher_name, $key, 'data buffer');
 #or
 $omac_raw = omac($cipher_name, $key, 'any data', 'more data', 'even more data');

=head2 omac_hex

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

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

=head2 omac_b64

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

$omac_b64 = omac_b64($cipher_name, $key, 'data buffer');
 #or
 $omac_b64 = omac_b64($cipher_name, $key, 'any data', 'more data', 'even more data');

=head2 omac_b64u

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

$omac_b64url = omac_b64u($cipher_name, $key, 'data buffer');
 #or
 $omac_b64url = omac_b64u($cipher_name, $key, 'any data', 'more data', 'even more data');
