Crypt::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');
