NAME

Crypt::Stream::Rabbit - Stream cipher Rabbit

SYNOPSIS

use Crypt::Stream::Rabbit;
# encrypt
$key = "1234567890123456";
$iv  = "12345678";
$stream = Crypt::Stream::Rabbit->new($key, $iv);
$ct = $stream->crypt("plain message");
# decrypt
$key = "1234567890123456";
$iv  = "12345678";
$stream = Crypt::Stream::Rabbit->new($key, $iv);
$pt = $stream->crypt($ct);

DESCRIPTION

Provides an interface to the Rabbit stream cipher.

METHODS

$stream = Crypt::Stream::Rabbit->new($key, $iv);
# $key .. keylen must be up to 16 bytes
# $iv  .. ivlen must be up to 8 bytes
$stream = Crypt::Stream::Rabbit->new($key);
#BEWARE: this is different from new($key, "")

$ciphertext = $stream->crypt($plaintext);
#or
$plaintext = $stream->crypt($ciphertext);

$random_key = $stream->keystream($length);

$stream->clone();
