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');
   $pmac_b64u = pmac_b64u($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
   $result_b64u = $d->b64umac; # Base64 URL Safe 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');
pmac_b64u¶
Logically joins all arguments into a single string, and returns its PMAC message authentication code encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$pmac_b64url = pmac_b64u($cipher_name, $key, 'data buffer'); #or $pmac_b64url = pmac_b64u($cipher_name, $key, 'any data', 'more data', 'even more data');
METHODS¶
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();
b64umac¶
$result_b64url = $d->b64umac();
