📛 NAME

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

🚀 Quick Reference

Use Case	Command	Description
Compute Whirlpool hash from string (raw)	whirlpool('data')	Binary output, functional interface
Compute Whirlpool hash from string (hex)	whirlpool_hex('data')	Hexadecimal output, functional interface
Compute Whirlpool hash from string (Base64)	whirlpool_b64('data')	Base64 with padding, functional interface
Compute Whirlpool hash from file	whirlpool_file('file.dat')	Binary output from file, functional interface
OO: create object, add data, get digest	$d->add('data'); $d->digest;	Object-oriented interface

📖 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);
