Crypt::Mac::F9(3)

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

 #or
 $d->add('any data', 'more data', 'even more data');

  addfile
 $d->addfile('filename.dat');
