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
new
$stream = Crypt::Stream::Rabbit->new($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, "")
crypt
$ciphertext = $stream->crypt($plaintext);
#or
$plaintext = $stream->crypt($ciphertext);
keystream
$random_key = $stream->keystream($length);
clone
$stream->clone();
