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 string');
$pmac_hex = pmac_hex($cipher_name, $key, 'data string');
$pmac_b64 = pmac_b64($cipher_name, $key, 'data string');
### 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 formDESCRIPTION
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 string');
#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.
$pmac_hex = pmac($cipher_name, $key, 'data string');
#or
$pmac_hex = pmac($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.
$pmac_b64 = pmac($cipher_name, $key, 'data string');
#or
$pmac_b64 = pmac($cipher_name, $key, 'any data', 'more data', 'even more data');METHODS
The OO interface provides the same set of functions as Crypt::Mac.
