Crypt::Mac::PMAC - Message authentication code PMAC
### 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
Provides an interface to the PMAC message authentication code (MAC) algorithm.
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';
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');
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');
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');
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');
$d = Crypt::Mac::PMAC->new($cipher_name, $key);
$d->clone();
$d->reset();
$d->add('any data'); #or $d->add('any data', 'more data', 'even more data');
$d->addfile('filename.dat'); #or $d->addfile(*FILEHANDLE);
$result_raw = $d->mac();
$result_hex = $d->hexmac();
$result_b64 = $d->b64mac();
$result_b64url = $d->b64umac();
