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();
