|
|
Crypt::Mac::PMAC - Message authentication code PMAC
|
|
|
|
=head1 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
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Provides an interface to the PMAC message authentication code (MAC) algorithm.
|
|
|
|
=head1 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';
|
|
|
|
=head1 FUNCTIONS
|
|
|
|
=head2 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');
|
|
|
|
=head2 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');
|
|
|
|
=head2 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');
|
|
|
|
=head2 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');
