NAME

Crypt::SaltedHash - Perl interface to functions that will assist in working with salted hashes.

SYNOPSIS

use Crypt::SaltedHash;

my $csh = Crypt::SaltedHash->new(algorithm => 'SHA-1');
$csh->add('secret');

my $salted = $csh->generate;
my $valid = Crypt::SaltedHash->validate($salted, 'secret');

DESCRIPTION

The Crypt::SaltedHash module provides an object oriented interface to create salted (or seeded) hashed of clear text data. The original formalization of this concept comes from RFC-3112 and is extended by the use of different digital agorithms.

METHODS

new([%options])

Returns a new Crypt::SaltedHash object. Possible keys for %options are:

- algorithm: It's also possible to use common string representations of the algorithm (e.g. "sha256", "SHA-384"). If the argument is missing, SHA-1 will be used by default.

obj()

add($data, ...)

Logically joins the arguments into a single string, and uses it to update the current digest state. For more details see Digest.

generate()

validate($hasheddata, $cleardata)

FUNCTIONS

none yet.
