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();
