Crypt::Mac::BLAKE2s(3)User Contributed Perl DocumentatioCrypt::Mac::BLAKE2s(3)

NAME
       Crypt::Mac::BLAKE2s - Message authentication code BLAKE2s MAC (RFC
       7693)

SYNOPSIS
	  ### Functional interface:
	  use Crypt::Mac::BLAKE2s qw( blake2s blake2s_hex );

	  # calculate MAC from string/buffer
	  $blake2s_raw	= blake2s($size, $key, 'data buffer');
	  $blake2s_hex	= blake2s_hex($size, $key, 'data buffer');
	  $blake2s_b64	= blake2s_b64($size, $key, 'data buffer');
	  $blake2s_b64u	= blake2s_b64u($size, $key, 'data buffer');

	  ### OO interface:
	  use Crypt::Mac::BLAKE2s;

	  $d = Crypt::Mac::BLAKE2s->new($size, $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 BLAKE2s message authentication code	(MAC)
       algorithm.

EXPORT
       Nothing is exported by default.

       You can export selected functions:

	 use Crypt::Mac::BLAKE2s qw(blake2s blake2s_hex	);

       Or all of them at once:

	 use Crypt::Mac::BLAKE2s ':all';

FUNCTIONS
   blake2s
       Logically joins all arguments into a single string, and returns its
       BLAKE2s message authentication code encoded as a	binary string.

	$blake2s_raw = blake2s($size, $key, 'data buffer');
	#or
	$blake2s_raw = blake2s($size, $key, 'any data',	'more data', 'even more	data');

   blake2s_hex
       Logically joins all arguments into a single string, and returns its
       BLAKE2s message authentication code encoded as a	hexadecimal string.

	$blake2s_hex = blake2s_hex($size, $key,	'data buffer');
	#or
	$blake2s_hex = blake2s_hex($size, $key,	'any data', 'more data', 'even more data');

   blake2s_b64
       Logically joins all arguments into a single string, and returns its
       BLAKE2s message authentication code encoded as a	Base64 string.

	$blake2s_b64 = blake2s_b64($size, $key,	'data buffer');
	#or
	$blake2s_b64 = blake2s_b64($size, $key,	'any data', 'more data', 'even more data');

   blake2s_b64u
       Logically joins all arguments into a single string, and returns its
       BLAKE2s message authentication code encoded as a	Base64 URL Safe	string
       (see RFC	4648 section 5).

	$blake2s_b64url	= blake2s_b64u($size, $key, 'data buffer');
	#or
	$blake2s_b64url	= blake2s_b64u($size, $key, 'any data',	'more data', 'even more	data');

METHODS
   new
	$d = Crypt::Mac::BLAKE2s->new($size, $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();
