Description :
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\";
AATTfrags = split(//, $data);
$digest1 = sha3_256_hex($data);
$state = Digest::SHA3->new(256);
for (AATTfrags) { $state->add($_) }
$digest2 = $state->hexdigest;
print $digest1 eq $digest2 ?
\"that\'s the ticket!\
\" : \"oops!\
\";
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 $sha3->hexdigest, \"\
\";
Note that for larger bit-strings, it\'s more efficient to use the
two-argument version _add_bits($data, $nbits)_, where _$data_ is in the
customary packed binary format used for Perl strings.
