Crypt::Mac::Pelican − Message authentication code Pelican (AES based MAC)
### Functional
interface:
use Crypt::Mac::Pelican qw( pelican pelican_hex );
# calculate MAC from string/buffer
$pelican_raw = pelican($key, 'data buffer');
$pelican_hex = pelican_hex($key, 'data buffer');
$pelican_b64 = pelican_b64($key, 'data buffer');
$pelican_b64u = pelican_b64u($key, 'data buffer');
### OO interface:
use Crypt::Mac::Pelican;
$d = Crypt::Mac::Pelican−>new($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 Pelican message authentication code (MAC) algorithm.
Nothing is exported by default.
You can export selected functions:
use Crypt::Mac::Pelican qw(pelican pelican_hex );
Or all of them at once:
use Crypt::Mac::Pelican ':all';
Logically joins all arguments into a single string, and returns its Pelican message authentication code encoded as a binary string.
$pelican_raw =
pelican($key, 'data buffer');
#or
$pelican_raw = pelican($key, 'any data', 'more data', 'even
more data');
Logically joins all arguments into a single string, and returns its Pelican message authentication code encoded as a hexadecimal string.
$pelican_hex =
pelican_hex($key, 'data buffer');
#or
$pelican_hex = pelican_hex($key, 'any data', 'more data',
'even more data');
Logically joins all arguments into a single string, and returns its Pelican message authentication code encoded as a Base64 string.
$pelican_b64 =
pelican_b64($key, 'data buffer');
#or
$pelican_b64 = pelican_b64($key, 'any data', 'more data',
'even more data');
Logically joins all arguments into a single string, and returns its Pelican message authentication code encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$pelican_b64url
= pelican_b64u($key, 'data buffer');
#or
$pelican_b64url = pelican_b64u($key, 'any data', 'more
data', 'even more data');
$d = Crypt::Mac::Pelican−>new($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();
