#NAME

Crypt::Mac::F9 - Message authentication code F9

#SYNOPSIS

### Functional interface:
use Crypt::Mac::F9 qw( f9 f9_hex );

# calculate MAC from string/buffer
$f9_raw  = f9($cipher_name, $key, 'data buffer');
$f9_hex  = f9_hex($cipher_name, $key, 'data buffer');
$f9_b64  = f9_b64($cipher_name, $key, 'data buffer');
$f9_b64u = f9_b64u($cipher_name, $key, 'data buffer');

### OO interface:
use Crypt::Mac::F9;

$d = Crypt::Mac::F9->new($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

#DESCRIPTION

Provides an interface to the F9 message authentication code (MAC) algorithm.

#EXPORT

Nothing is exported by default.

You can export selected functions:

use Crypt::Mac::F9 qw(f9 f9_hex );

Or all of them at once:

use Crypt::Mac::F9 ':all';

#FUNCTIONS

#f9

Logically joins all arguments into a single string, and returns its F9 message authentication code encoded as a binary string.

$f9_raw = f9($cipher_name, $key, 'data buffer');
#or
$f9_raw = f9($cipher_name, $key, 'any data', 'more data', 'even more data');

#f9_hex

Logically joins all arguments into a single string, and returns its F9 message authentication code encoded as a hexadecimal string.

$f9_hex = f9_hex($cipher_name, $key, 'data buffer');
#or
$f9_hex = f9_hex($cipher_name, $key, 'any data', 'more data', 'even more data');

#f9_b64

Logically joins all arguments into a single string, and returns its F9 message authentication code encoded as a Base64 string.

$f9_b64 = f9_b64($cipher_name, $key, 'data buffer');
#or
$f9_b64 = f9_b64($cipher_name, $key, 'any data', 'more data', 'even more data');

#f9_b64u

Logically joins all arguments into a single string, and returns its F9 message authentication code encoded as a Base64 URL Safe string (see RFC 4648 section 5).

$f9_b64url = f9_b64u($cipher_name, $key, 'data buffer');
#or
$f9_b64url = f9_b64u($cipher_name, $key, 'any data', 'more data', 'even more data');

#METHODS

#new

$d = Crypt::Mac::F9->new($cipher_name, $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();
