NAME

Digest::Groestl - Perl interface to the Groestl digest algorithm

SYNOPSIS

# Functional interface
use Digest::Groestl qw(groestl_256 groestl_256_hex groestl_256_base64);

$digest = groestl_256($data);
$digest = groestl_256_hex($data);
$digest = groestl_256_base64($data);

# Object-oriented interface
use Digest::Groestl;

$ctx = Digest::Groestl->new(256);

$ctx->add($data);
$ctx->addfile(*FILE);

$digest = $ctx->digest;
$digest = $ctx->hexdigest;
$digest = $ctx->b64digest;

DESCRIPTION

The Digest::Groestl module provides an interface to the Groestl message digest algorithm. Groestl is a candidate in the NIST SHA-3 competition.

This interface follows the conventions set forth by the Digest module.

FUNCTIONS

The following functions are provided by the Digest::Groestl module. None of these functions are exported by default.

groestl_224($data, ...)

groestl_256($data, ...)

groestl_384($data, ...)

groestl_512($data, ...)

Logically joins the arguments into a single string, and returns its Groestl digest encoded as a binary string.

groestl_224_hex($data, ...)

groestl_256_hex($data, ...)

groestl_384_hex($data, ...)

groestl_512_hex($data, ...)

Logically joins the arguments into a single string, and returns its Groestl digest encoded as a hexadecimal string.

groestl_224_base64($data, ...)

groestl_256_base64($data, ...)

groestl_384_base64($data, ...)

groestl_512_base64($data, ...)

Logically joins the arguments into a single string, and returns its Groestl digest encoded as a Base64 string, without any trailing padding.

METHODS

The object-oriented interface to Digest::Groestl is identical to that described by Digest, except for the following:

new

$groestl = Digest::Groestl->new(256)

The constructor requires the algorithm to be specified. It must be one of: 224, 256, 384, 512.

algorithm

hashsize

Returns the algorithm used by the object.
