Crypt::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);
