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');
