perl-Digest-SHA3

Digest::SHA3 is written in C for speed. If your platform lacks a C
compiler, perhaps you can find the module in a binary form compatible with
your particular processor and operating system.
The programming interface is easy to use: it's the same one found in CPAN's
Digest module. So, if your applications currently use Digest::SHA and you'd
prefer the newer flavor of the NIST standard, it's a simple matter to
convert them.
The interface provides two ways to calculate digests: all-at-once, or in
stages. To illustrate, the following short program computes the SHA3-256
digest of "hello world" using each approach:
use Digest::SHA3 qw(sha3_256_hex);

$data = "hello world";
@frags = split(//, $data);


$digest1 = sha3_256_hex($data);
$state = Digest::SHA3->new(256);
    for (@frags) { $state->add($_) }
    $digest2 = $state->hexdigest;
print $digest1 eq $digest2 ?
	"that's the ticket!\n" : "oops!\n";


To calculate the digest of an n-bit message where n is not a multiple of
8, use the add_bits() method. For example, consider the 446-bit message
consisting of the bit-string "110" repeated 148 times, followed by "11".
Here's how to display its SHA3-512 digest:
use Digest::SHA3;
$bits = "110" x 148 . "11";
$sha3 = Digest::SHA3->new(512)->add_bits($bits);
print $sha3->hexdigest, "\n";


Note that for larger bit-strings, it's more efficient to use the
two-argument version add_bits($data, $nbits), where $data is in the
customary packed binary format used for Perl strings.
