NAME

Crypt::Mac::PMAC - Message authentication code PMAC

SYNOPSIS

   ### Functional interface:
   use Crypt::Mac::PMAC qw( pmac pmac_hex );

   # calculate MAC from string/buffer
   $pmac_raw = pmac($cipher_name, $key, 'data buffer');
   $pmac_hex = pmac_hex($cipher_name, $key, 'data buffer');
   $pmac_b64 = pmac_b64($cipher_name, $key, 'data buffer');

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

   $d = Crypt::Mac::PMAC->new($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 PMAC message authentication code (MAC) algorithm.

EXPORT

Nothing is exported by default.

You can export selected functions:

  use Crypt::Mac::PMAC qw(pmac pmac_hex );

Or all of them at once:

  use Crypt::Mac::PMAC ':all';

FUNCTIONS

pmac

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

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

pmac_hex

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

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

pmac_b64

Logically joins all arguments into a single string, and returns its PMAC message authentication code encoded as a BASE64 string.

 $pmac_b64 = pmac_b64($cipher_name, $key, 'data buffer');
 #or
 $pmac_b64 = pmac_b64($cipher_name, $key, 'any data', 'more data', 'even more data');

METHODS

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

new

 $d = Crypt::Mac::PMAC->new($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();
