=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');
