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 string');
   $f9_hex = f9_hex($cipher_name, $key, 'data string');
   $f9_b64 = f9_b64($cipher_name, $key, 'data string');

   ### 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

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 string');
 #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.

 $f9_hex = f9($cipher_name, $key, 'data string');
 #or
 $f9_hex = f9($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.

 $f9_b64 = f9($cipher_name, $key, 'data string');
 #or
 $f9_b64 = f9($cipher_name, $key, 'any data', 'more data', 'even more data');

METHODS

The OO interface provides the same set of functions as Crypt::Mac.

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_base64 = $d->b64mac();
