NAME
    Crypt::Digest::Whirlpool - Hash function Whirlpool [size: 512 bits]

SYNOPSIS
       ### Functional interface:
       use Crypt::Digest::Whirlpool qw( whirlpool whirlpool_hex whirlpool_b64 whirlpool_b64u
                                    whirlpool_file whirlpool_file_hex whirlpool_file_b64 whirlpool_file_b64u );

       # calculate digest from string/buffer
       $whirlpool_raw  = whirlpool('data string');
       $whirlpool_hex  = whirlpool_hex('data string');
       $whirlpool_b64  = whirlpool_b64('data string');
       $whirlpool_b64u = whirlpool_b64u('data string');
       # calculate digest from file
       $whirlpool_raw  = whirlpool_file('filename.dat');
       $whirlpool_hex  = whirlpool_file_hex('filename.dat');
       $whirlpool_b64  = whirlpool_file_b64('filename.dat');
       $whirlpool_b64u = whirlpool_file_b64u('filename.dat');
       # calculate digest from filehandle
       $whirlpool_raw  = whirlpool_file(*FILEHANDLE);
       $whirlpool_hex  = whirlpool_file_hex(*FILEHANDLE);
       $whirlpool_b64  = whirlpool_file_b64(*FILEHANDLE);
       $whirlpool_b64u = whirlpool_file_b64u(*FILEHANDLE);

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

       $d = Crypt::Digest::Whirlpool->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 Whirlpool digest algorithm.

EXPORT
    Nothing is exported by default.

    You can export selected functions:

      use Crypt::Digest::Whirlpool qw(whirlpool whirlpool_hex whirlpool_b64 whirlpool_b64u
                                          whirlpool_file whirlpool_file_hex whirlpool_file_b64 whirlpool_file_b64u);

    Or all of them at once:

      use Crypt::Digest::Whirlpool ':all';

FUNCTIONS
  whirlpool
    Logically joins all arguments into a single string, and returns its
    Whirlpool digest encoded as a binary string.

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

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

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

  whirlpool_b64
    Logically joins all arguments into a single string, and returns its
    Whirlpool digest encoded as a Base64 string, with trailing '=' padding.

     $whirlpool_b64 = whirlpool_b64('data string');
     #or
     $whirlpool_b64 = whirlpool_b64('any data', 'more data', 'even more data');

  whirlpool_b64u
    Logically joins all arguments into a single string, and returns its
    Whirlpool digest encoded as a Base64 URL Safe string (see RFC 4648
    section 5).

     $whirlpool_b64url = whirlpool_b64u('data string');
     #or
     $whirlpool_b64url = whirlpool_b64u('any data', 'more data', 'even more data');

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

     $whirlpool_raw = whirlpool_file('filename.dat');
     #or
     $whirlpool_raw = whirlpool_file(*FILEHANDLE);

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

     $whirlpool_hex = whirlpool_file_hex('filename.dat');
     #or
     $whirlpool_hex = whirlpool_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.

  whirlpool_file_b64
    Reads file (defined by filename or filehandle) content, and returns its
    Whirlpool digest encoded as a Base64 string, with trailing '=' padding.

     $whirlpool_b64 = whirlpool_file_b64('filename.dat');
     #or
     $whirlpool_b64 = whirlpool_file_b64(*FILEHANDLE);

  whirlpool_file_b64u
    Reads file (defined by filename or filehandle) content, and returns its
    Whirlpool digest encoded as a Base64 URL Safe string (see RFC 4648
    section 5).

     $whirlpool_b64url = whirlpool_file_b64u('filename.dat');
     #or
     $whirlpool_b64url = whirlpool_file_b64u(*FILEHANDLE);

METHODS
    The OO interface provides the same set of functions as Crypt::Digest.

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

  clone
     $d->clone();

  reset
     $d->reset();

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

  addfile
     $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::Whirlpool->hashsize();
     #or
     Crypt::Digest::Whirlpool::hashsize();

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

  hexdigest
     $result_hex = $d->hexdigest();

  b64digest
     $result_b64 = $d->b64digest();

  b64udigest
     $result_b64url = $d->b64udigest();
