NAME
Crypt::Mac::BLAKE2b - Message authentication code BLAKE2b MAC (RFC 7693)
SYNOPSIS
### Functional interface: use Crypt::Mac::BLAKE2b qw( blake2b blake2b_hex ); # calculate MAC from string/buffer $blake2b_raw = blake2b($size, $key, 'data buffer'); $blake2b_hex = blake2b_hex($size, $key, 'data buffer'); $blake2b_b64 = blake2b_b64($size, $key, 'data buffer'); $blake2b_b64u = blake2b_b64u($size, $key, 'data buffer'); ### OO interface: use Crypt::Mac::BLAKE2b; $d = Crypt::Mac::BLAKE2b->new($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 BLAKE2b message authentication code (MAC) algorithm.
EXPORT
Nothing is exported by default.
You can export selected functions:
use Crypt::Mac::BLAKE2b qw(blake2b blake2b_hex );
Or all of them at once:
use Crypt::Mac::BLAKE2b ':all';
FUNCTIONS
blake2b
Logically joins all arguments into a single string, and returns its BLAKE2b message authentication code encoded as a binary string.
$blake2b_raw = blake2b($size, $key, 'data buffer'); #or $blake2b_raw = blake2b($size, $key, 'any data', 'more data', 'even more data');
blake2b_hex
Logically joins all arguments into a single string, and returns its BLAKE2b message authentication code encoded as a hexadecimal string.
$blake2b_hex = blake2b_hex($size, $key, 'data buffer'); #or $blake2b_hex = blake2b_hex($size, $key, 'any data', 'more data', 'even more data');
blake2b_b64
Logically joins all arguments into a single string, and returns its BLAKE2b message authentication code encoded as a Base64 string.
$blake2b_b64 = blake2b_b64($size, $key, 'data buffer'); #or $blake2b_b64 = blake2b_b64($size, $key, 'any data', 'more data', 'even more data');
blake2b_b64u
Logically joins all arguments into a single string, and returns its BLAKE2b message authentication code encoded as a Base64 URL Safe string (see RFC 4648 section 5).
$blake2b_b64url = blake2b_b64u($size, $key, 'data buffer'); #or $blake2b_b64url = blake2b_b64u($size, $key, 'any data', 'more data', 'even more data');
