NAME

Crypt::Stream::Sosemanuk - Stream cipher Sosemanuk

SYNOPSIS

   use Crypt::Stream::Sosemanuk;

   # encrypt
   $key = "1234567890123456";
   $iv  = "123456789012";
   $stream = Crypt::Stream::Sosemanuk->new($key, $iv);
   $ct = $stream->crypt("plain message");

   # decrypt
   $key = "1234567890123456";
   $iv  = "123456789012";
   $stream = Crypt::Stream::Sosemanuk->new($key, $iv);
   $pt = $stream->crypt($ct);

DESCRIPTION

Provides an interface to the Sosemanuk stream cipher.

METHODS

new

 $stream = Crypt::Stream::Sosemanuk->new($key, $iv);
 # $key .. keylen must be multiple of 4 bytes
 # $iv  .. ivlen must be multiple of 4 bytes (OPTIONAL)

crypt

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

keystream

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

clone

 $stream->clone();
