   # calculate digest from string/buffer
   $sha3_512_raw  = sha3_512('data string');
   $sha3_512_hex  = sha3_512_hex('data string');
   $sha3_512_b64  = sha3_512_b64('data string');
   $sha3_512_b64u = sha3_512_b64u('data string');
   # calculate digest from file
   $sha3_512_raw  = sha3_512_file('filename.dat');
   $sha3_512_hex  = sha3_512_file_hex('filename.dat');
   $sha3_512_b64  = sha3_512_file_b64('filename.dat');
   $sha3_512_b64u = sha3_512_file_b64u('filename.dat');
   # calculate digest from filehandle
   $sha3_512_raw  = sha3_512_file(*FILEHANDLE);
   $sha3_512_hex  = sha3_512_file_hex(*FILEHANDLE);
   $sha3_512_b64  = sha3_512_file_b64(*FILEHANDLE);
   $sha3_512_b64u = sha3_512_file_b64u(*FILEHANDLE);

   ### OO interface:
   use Crypt::Digest::SHA3_512;

   $d = Crypt::Digest::SHA3_512->new;
   $d->add('any data');
   $d->addfile('filename.dat');
   $d->addfile(*FILEHANDLE);
   $result_raw  = $d->digest;     # raw bytes
   $result_hex  = $d->hexdigest;  # hexadecimal form
   $result_b64  = $d->b64digest;  # Base64 form
   $result_b64u = $d->b64udigest; # Base64 URL Safe form

DESCRIPTION
Provides an interface to the SHA3_512 digest algorithm.

EXPORT
Nothing is exported by default.

You can export selected functions:

  use Crypt::Digest::SHA3_512 qw(sha3_512 sha3_512_hex sha3_512_b64 sha3_512_b64u
                                      sha3_512_file sha3_512_file_hex sha3_512_file_b64 sha3_512_file_b64u);

Or all of them at once:

  use Crypt::Digest::SHA3_512 ':all';

FUNCTIONS

  sha3_512
Logically joins all arguments into a single string, and returns its SHA3_512 digest encoded as a binary string.

 $sha3_512_raw = sha3_512('data string');
 #or
 $sha3_512_raw = sha3_512('any data', 'more data', 'even more data');

  sha3_512_hex
Logically joins all arguments into a single string, and returns its SHA3_512 digest encoded as a hexadecimal string.

 $sha3_512_hex = sha3_512_hex('data string');
 #or
 $sha3_512_hex = sha3_512_hex('any data', 'more data', 'even more data');

  sha3_512_b64
Logically joins all arguments into a single string, and returns its SHA3_512 digest encoded as a Base64 string, with trailing '=' padding.

 $sha3_512_b64 = sha3_512_b64('data string');
 #or
 $sha3_512_b64 = sha3_512_b64('any data', 'more data', 'even more data');

  sha3_512_b64u
Logically joins all arguments into a single string, and returns its SHA3_512 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

 $sha3_512_b64url = sha3_512_b64u('data string');
 #or
 $sha3_512_b64url = sha3_512_b64u('any data', 'more data', 'even more data');

  sha3_512_file
Reads file (defined by filename or filehandle) content, and returns its SHA3_512 digest encoded as a binary string.

 $sha3_512_raw = sha3_512_file('filename.dat');
 #or
 $sha3_512_raw = sha3_512_file(*FILEHANDLE);

  sha3_512_file_hex
Reads file (defined by filename or filehandle) content, and returns its SHA3_512 digest encoded as a hexadecimal string.

 $sha3_512_hex = sha3_512_file_hex('filename.dat');
 #or
 $sha3_512_hex = sha3_512_file_hex(*FILEHANDLE);

BEWARE: You have to make sure that the filehandle is in binary mode before you pass it as argument to the addfile() method.

  sha3_512_file_b64
Reads file (defined by filename or filehandle) content, and returns its SHA3_512 digest encoded as a Base64 string, with trailing '=' padding.

 $sha3_512_b64 = sha3_512_file_b64('filename.dat');
 #or
 $sha3_512_b64 = sha3_512_file_b64(*FILEHANDLE);

  sha3_512_file_b64u
Reads file (defined by filename or filehandle) content, and returns its SHA3_512 digest encoded as a Base64 URL Safe string (see RFC 4648 section 5).

 $sha3_512_b64url = sha3_512_file_b64u('filename.dat');
 #or
 $sha3_512_b64url = sha3_512_file_b64u(*FILEHANDLE);

 $d = Crypt::Digest::SHA3_512->new();

  clone
 $d->clone();

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

  add_bits
 $d->add_bits($bit_string);   # e.g. $d->add_bits("111100001010");
 #or
 $d->add_bits($data, $nbits); # e.g. $d->add_bits("\xF0\xA0", 16);

  hashsize
 $d->hashsize;
 #or
 Crypt::Digest::SHA3_512->hashsize();
 #or
 Crypt::Digest::SHA3_512::hashsize();

  digest
 $result_raw = $d->digest();
