NAME
    Crypt::Digest::SHAKE - Hash functions SHAKE128, SHAKE256 from SHA3 family

SYNOPSIS
       use Crypt::Digest::SHAKE

       $d = Crypt::Digest::SHAKE->new(128);
       $d->add('any data');
       $d->addfile('filename.dat');
       $d->addfile(*FILEHANDLE);
       $part1 = $d->done(100); # 100 raw bytes
       $part2 = $d->done(100); # another 100 raw bytes
       #...

DESCRIPTION
    Provides an interface to the SHA3's sponge function SHAKE.

METHODS
  new
     $d = Crypt::Digest::SHA3-SHAKE->new($num);
     # $num ... 128 or 256

  clone
     $d->clone();

  reset
     $d->reset();

  add
     $d->add('any data');
     #or

  addfile
     $d->addfile('filename.dat');
     #or

  done
     $result_raw = $d->done($len);
     # can be called multiple times
