Crypt::Digest::WhirlpoUser)Contributed Perl DocumenCrypt::Digest::Whirlpool(3)

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();
