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();

SEE ALSO

Crypt::Stream::RC4, Crypt::Stream::ChaCha, Crypt::Stream::Salsa20, Crypt::Stream::Sober128
