Crypt::Mac::PMAC(3) User Contributed Perl Documentation Crypt::Mac::PMAC(3)

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();
